I don’t know how many people are reading this now and how many might start following it later, but I find writing for other people helps me get my own thoughts in order. So, thanks for being my rubber duck.
I started writing out a much longer and more boring post but then killed it off as things congealed. In a condensed form, here are my hopes for “version 1.5” of my setup in the next few months:
A Sound Of Thunder goes. The space is reserved against other uses.
Field Kit FX and its reverb tanks go — replaced functionally by Chase Bliss Dark World (shipping at the new year) and u‑he Twangström (currently in beta and f**king brilliant).
The fate of EarthQuaker Afterneath depends on how I feel with Dark World on the board and if I think something else would be more useful/fun.
Reclaimed pedalboard space goes partly to a 16n Fader Bank, which is an open-source controller that works with MIDI, CV and i2c (used by Teletype). This should be amazing for sequencing in Teletype and controlling everything else. There’s no current ETA on a production run for it.
The rest of the space could go to a 4ms Pod or lunchbox case, giving me 32-60 more HP for Eurorack modules. This is contigent on other module vacancies/replacements — if I don’t do it I’m likely approximately cost-neutral with all these changes. Strong contenders for space include the successor to Mutable Instruments Clouds or a Qu-Bit Nebulae V2.
Of course another pedal or two could make it to the pedalboard, depending on space. But there are no really strong candidates at the moment given what Dark World is likely to do for me.
Mimetic Digitalis and/or Maze get replaced. (Maze is about to receive an update adding a feature I asked for which may be a game changer.) But I’m expecting great things out of u-he CVilization, which is the size of MD and is a 4×4 matrix mixer with several sequencer-friendly features, plus three other modes that may make it indispensible. It’s possible I’ll replace my A-138m with one also.
If CVilization or the 16n don’t come to fruition or I find them lacking, there are several other options. For sequencing: Befaco Muxlicer or Pittsburgh Micro Sequence. For control, Noise Engineering Lapsus Os or Michigan Synth Works Plancks II. For matrix mixing, the 4ms VCA Matrix or Rebel Tech Mix 04.
If Cvil and 16n and “Clouds 2” are all utterly brilliant, I see myself with about 19HP of free space with no claim on it, without adding a small case. That’s my hope.
Since I don’t love the 2hp Trim for pedal conversion, it’d be nice to put in something better suited; it wouldn’t take much more space anyhow.
I have no plans to add more VCOs even if space becomes available. If I want to change anything there, something’s got to go. Double Helix or Hertz Donut perhaps, but I like both of those so it’s not highly likely.
All but one in this final row are by Mutable Instruments, and all but three are 2018 releases. Three songs on the upcoming album were done on this row alone.
Starting at left, Mutable Instruments Marbles is a humdinger. The left half generates three trigger streams, from a steady clock to a jittery one to drum patterns and random variations; it can use its own timing or follow an incoming clock or learn rhythmic patterns. The right half generates random CVs synchronized to the left half or an external clock; it uses a clever quantizer that filters notes by probability, which you can train by playing pitch CVs into it. It can also sample CVs from an input and distribute them according to its clock timing and shift register logic. For each side, you can engage “Deja Vu” which plays the rhythms and/or CVs in a loop, with an adjustable probability of altering that loop each time it plays through. There’s also another random CV generator just for kicks. It may sound like a lot of complex stuff, but it’s mostly easy to use and the results are fantastic — it made me change my mind about modules that generate random signals. To me it’s a great partner for Teletype. 5/5.
A shift register passes a value along a chain each time it is triggered, in “Row, Row, Row, Your Boat” fashion. Some variations on shift registers feed back into themselves in order to generate repeating or chaotic patterns; linear-feedback shift registers (LFSR) were used in the 80s to generate noise for arcade games.
Sporting six sliders, Stages is a very versatile modulation source. Each segment can be set to ramp, hold, or step behavior, and segments can be grouped together by patching in gate signals. In an intuitive way you can patch simple or complex envelopes, LFOs, sequencers, sequential switches, delays, sample-and-holds, slews, manual sliders, and combinations of those. You can run audio through it to make it a little grungy and/or filter it, or generate chiptune-like audio. You can chain multiple Stages together, or to itself for the “Ouroboros” easter egg mode, a harmonic oscillator (I haven’t tried that yet). Extremely cool and very well designed, especially good for smaller systems but useful everywhere. 5/5.
Plaits is the successor to Braids, the company’s first big hit in the Eurorack world. A digital oscillator with 16 different synthesis models, each with three parameters, and many having cool variants on the secondary output. It also has a built-in decay envelope and LPG, so it’s possible to use it with a minimum of other help. As I’ve said previously, it’s a very good partner for Rings. A very solid module. 4.5/5.
Fourth and fifth from left I have a pair of Rings, the module that got me into all this. I’ve mentioned it before. I would not have it as the only sound source in my system (that would be Plaits for a tiny setup, or E370 for less small) but I do like it a lot. At least for Materials, it was kind of awesome having two — time will tell if I keep them both. 5/5.
With one red knob installed, Shades is a three-channel atteunverter and mixer. Any channel without an input patched generates an offset, and without an output patched, mixes with the next channel. It’s nicely controllable. 4.5/5.
The penultimate module is Tides, 2018 revision. It’s a function generator, but one where you can set the cycle time and shape separately. This is perfect for VCO and LFO use, and unusual but functional for envelopes. Tides also has its own filter/wavefolder combination, and a PLL mode that follows an incoming clock or VCO. The 2018 version, aside from being more accurate and having attenuverters for every input, has four modes that can shift the level, phase or frequency (with harmonic relationships) across its four outputs, which extends it capabilities nicely. 5/5.
On the corner is Livestock Electronics Maze. It’s sort of a combination matrix mixer (like the A-138m) and sequential switch — there are 16 “pages” of matrix settings which can be selected by buttons, stepped through with a trigger or selected by CV, and it can jump or fade smoothly between them. It’s a thrilling concept, but in practice I don’t find myself using it as much as I thought. I often consider whether I should replace it, but then I come up with scenarios where it was exactly what I needed, and nothing else its size would do. 4/5.
This is the current state of my pedalboard, or really, a shelf hanging over the Mantis at a 45 degree angle. Guitar FX pedals offer some neat alternatives to software-based effects or Eurorack effects, but they run at lower voltage levels generally, thus the need for attenuation before and boosting after to work with them.
In the upper left are a pair of spring reverb tanks. I use those with the Koma Elektronik Field Kit FX, in the lower right. The FKFX has a Eurorack panel option, but it’s pretty wide. Aside from the spring reverb driver, it has a PT2399-based digital delay (cheap and gets weird and crunchy at long delay times, which can be great), a frequency shifter, a 4-input VCA mixer with tone control on 3 channel and overdrive on the fourth, a little modulation source that can be a 4-step sequencer or an ADSR envelope, and four assignable CVs. I’ve used it particularly with the Dynamo for setting up feedback loops with the reverb and frequency shifter. Spring reverb is kind of fun to mess with, but also very touchy to work with. 3.5/5.
In the upper right is a Rochambeau Musical Apparatus Monobius, custom 6-knob variant. This is a combination ring modulator and fuzz with bandpass filter. It’s very noisy and odd, and was one of those trades I did on a whim rather than a plan, but it adds some neat flavor. 3.5/5.
Left of the FKFX (because on pedals, the signal flow usually goes right-to-left) is WMD Geiger Counter, in a rare distressed black colorway (they are normally screaming yellow). It’s an 8-bit waveshaper, distortion and sample/bit reduction device. With precise enough control over input levels, it is a nice alternative to more traditional wavefolders. 3.5/5.
Next is Red Panda Tensor, a sort of quasi-tape looper, pitch shifter, time shifter, reverser, randomizer thing. It is cleverly set up; it listens even when “off” so you can instantly get a reversed repeat of what you were playing; it can judge when to (smoothly) reset its buffer to prevent overflows when you’re playing back repeats more slowly than they came in, and so on. Sometimes it feels like a human playing counterpoint to me; other times it just makes a neat background wash of stuff, or a sweet chorused sound. Its stomp switches are the non-clicky type (and can be switched between momentary and latching), which I prefer since I don’t use it with my feet. 5/5.
Then there’s EarthQuaker Devices Afterneath. It lives somewhere between delay and reverb. with a little chain of echoes that can be diffused. It’s very easy to get infinite feedback going with it and keep it under control. The minimum pre-delay time is longer than I would prefer, which limits the flexibility a little. A nice non-clicky stomp switch on it. 4/5.
And finally there’s the Zoom MultiStomp MS-70CDR. It’s a multi-effect with several classic and modern versions of chorus, delay, reverb, and other modulation and a few utilities like EQ, noise gate and compressor. With three push encoders and an LCD screen it’s a little friendlier for my purposes than some multi-effect pedals, but it’s still occasionally just a little bit tedious to set up. The processing is pretty great, the sound quality can be a bit noisy at times (as guitar pedals sometimes are) but not terribly so, and the price was fantastic for something this flexible. 4/5.
I have a Chase Bliss Dark World on preorder, which should ship around the start of the year. It provides three reverb algorithms on the “world” side, and three effects on the “dark” side to add gloom or shimmer or the infinite void. You can run the two sides in either order or in parallel and there’s a master tone control to darken it more if need be. The demos have been impressive, and I may see this replacing the FKFX (thanks to a spring reverb model) and maybe the Afterneath too. Hopefully a 5/5…?
Since writing that last post, I had a bee in my bonnet about replacing the Tyme Sefari + A Sound Of Thunder, and spent the weekend researching the alternatives.
Long story short: I have decided to keep the Tyme Sefari. Sure it’s lo-fi, but I had occasionally thought about getting a Doepfer BBD (analog bucket-brigade delay) precisely because it is lo-fi, in kind of a similar-ish way. Durrr… anyway, running Tyme Sefari’s main output through a filter and turning it down a bit dark actually sounds really lovely.
And I like the logic of how Tyme Sefari works, which is unique. Only one other module I’ve found can do everything it can — SDS Reflex Liveloop — but that one works through a bunch of different modes instead of a unified, fluid design.
I’ll probably ditch the A Sound Of Thunder expander though. The only feature on it I really like is the slightly awkward extra channel for stereo, and I can let go of that. Most of my hardware stuff runs in mono channels anyway, or else mid/side encoding.
Mono (monoaural) vs. stereo is probably familiar — either one audio channel, or two related channels. Stereo typically uses “LR” encoding — left and right, predictably enough. “MS” or mid/side stereo, instead treats one channel as the middle of the sound field, and the other as the differences that happen on the edges.
Mid/side is not very intuitive to think about, but it’s pretty simple to convert from LR. Just add the two channels together to get the mid signal, and subtract them from each other to get the side signal. Some attenuation might be needed to avoid distortion if the inputs are already loud.
With mid/side encoding, you can’t make distinct left/right movements — But it’s very handy for getting a balanced yet wide and dramatic sound by processing the mid and side differently or even using different sources, and I like working with it especially in modular.
There are a couple of mid/side encoder modules available, but I usually do the conversion with a plugin.
With that wrapped up, it’s time to look at the top row of the Mantis!
At left is the second half of the Doepfer A-180-9 Multicore mentioned previously. Plugged into the top are the stereo outputs from one of my FX pedals, sent onward to my audio interface without really being processed by any of my modular gear.
The next module, with the amber-on-black screen, is Monome Teletype. This module lets you write short snippets of code with a computer keyboard (wireless in my case) which run whenever triggers are received or its internal metronome ticks. It has a single CV input, and can output gates/triggers and control voltages — so you can use it to manipulate gates, play stored sequences or generate them algorithmically, record CVs as a new sequence, generate envelopes or LFOs, and so on. It’s extremely flexible, it just requires thinking a bit like a programmer — which I am. Mine’s mounted upside-down with a firmware-flipped display, to keep the jacks out of the way of the screen. 5/5.
Algorithmic sequencing or algorithmic composition is the practice of using some relatively simple math and logic to determine rhythms and/or pitches, rather than explicitly composing them. Algorithms may include some stored patterns, but these are the basis of further logical or mathematical operations.
Generative patches are those where the interaction of electronic circuits drives the music. The Krell patch is an iconic example.
Sometimes the lines between the two are blurred or erased, with digital algorithms feeding analog processors and vice versa.
Circuit Abbey G8 is on its right. It’s a clock divider or clock distributor, which is something Teletype can do very easily. But unlike the Teletype, it runs fast enough to send audio through it and get back squarewave audio in lower octaves. Sometimes I keep the Teletype busy with other things anyway. It’s useful enough to justify keeping it around. 4/5.
And then there’s Noise Engineering Mimetic Digitalis. It’s a 4-channel sequencer laid out on a 4×4 grid, which can be navigated via triggers or CV in two dimensions or linearly or randomly, all at the same time. I really like this one in theory; the problem is I don’t often find myself using it that much in practice. I can imitate most of its behavior in Teletype and in another module later in this row. I still feel like I should give it more of a chance, though. 3/5.
Next, with some cables plugged in and sent overhead, is ALM Busy Circuits S.B.G It attenuates an audio signal from Eurorack levels down to the levels expected by guitar FX pedals, and raises a pedal-level signal back to Eurorack levels. It offers a dry/wet knob, and a further converter from Eurorack CV to 3V or 5V “expression pedal” inputs for FX pedals. It does the job, though I feel like the knob response/ranges are a little odd and the layout could have been friendlier (I should at least turn it upside-down). 4/5.
Dry/wet or simply “mix” is a common control on FX. The “dry” signal is the input of any FX unit or chain, while its output is “wet.” Blending them is a nice way to avoid overwhelming your audio with too much of a good thing, e.g. reverb.
So slim you might miss it, 2hp Trim is next. It’s a dual passive attenuator. Along with the S.B.G I’m using it to lower Eurorack signals to guitar FX levels, since I’ve got a few FX I want to use separately. It’s actually not calibrated for this purpose, with the right range being somewhere in the lowest 1/10 or so of the knob. 2/5.
To its right is Circuit Abbey Gozinta. It’s an amplifier to give a clean boost to, you guessed it, signals coming in from FX pedals. Or any other source where the voltage might be lower than you want, or where you want to overdrive a signal to distort it. It does its job admirably. 4.5/5.
The wide module after that is Pittsburgh Lifeforms Double Helix. It’s got a West Coast vibe overall, with a pair of oscillators, an LFO, a wavefolder, an LPG, and a dual modulation bus that makes it easy to assign things to modulate other things. It’s also haunted by crosstalk and weird interactions within the module, which can annoy or please in equal measure. The oscillators are kind of “chewy” and well suited to the character of the folder and LPG (which is a simplified Dynamic Impulse Filter). It sounds great, and whenever I consider dropping it, its unique character grabs me and changes my mind. 4/5.
Next, with the big knob backlit in blue-green, is a DIY build (by someone else) of Mutable Instruments Warps. The general idea behind this one is it combines and mangles two audio signals in various ways — though it also has its own VCO which does rather nice phase modulation. I sold my first one, and months later, traded for this because I missed it. I don’t actually use it a lot, but it’s occasionally welcome. 3.5/5.
Mutable Instruments is one of the popular Eurorack module brands. Its founder started with open-source, DIY desktop synths and chose to continue using that model upon entering the Eurorack market. This has its pros and cons; parts of Mutable Instruments code live on in many other open-source projects and people have made alternate firmware to add new functions to the modules. People have also independently done DIY builds of the modules, or smaller redesigned versions, for themselves or others.
The black module with the blue display is uO_C, or micro Ornament & Crime. This is part of an open-source hardware and software project, which is itself partly based on Mutable Instruments code. I have Hemisphere Suite installed on mine, which is a set of dozens of utility apps, ranging from envelope generators to Euclidean generators to quantizers to quixotic sequencers. There’s almost always something useful for it to do. 4.5/5.
The narrower black module to its right is Erica Synths Pico A Logic. Given two inputs, it returns the sum, difference, maximum and minimum voltages. Hemisphere Suite can do that too, but this is better suited to audio signals since it’s not limited by rate. I don’t use it a lot, but it fills an awkwardly small space for which I don’t have a better use at the moment. 3.5/5.
The neighbor with the red buttons is Ladik P-075 Dual Switch. It’s a simple, passive module where you can connect or disconnect any signal via a manual toggle switch and button combination. The button inverts the state of the switch, which is clever. It’s handy to run constant voltages through just to use as a gate source, or to mute parts of a patch. 4/5.
The wood panel on the right side end is a Bastl Dynamo. It’s a busy module, where the top part combines an envelope follower, comparator and some inverters and rectifiers to create a control source for a VCA for compression — lowering the level when it gets too high. Of course it can be patched in other ways as well. The bottom section is an inverter and a very fast A/B switch, and I don’t fully understand the intention of including it rather than a VCA, but it can do some cool stuff once in a while. Again, I don’t like the wood panel and was supposed to have received an aluminum one. 3.5/5.
One more row to cover, plus some FX and mentions of favorite software and maybe a couple other things!
While writing this post, I started patching up a generative piece using two LFOs ANDed and XORed together, inverted, fed to the G8… all those gates clocked Mimetic Digitalis, some envelope generation, delay syncing and so on. By the time I finished it was quite a busy patch, the kind that uses up most of my cables. If I still think well enough of it tomorrow, I’ll be submitting it to the Ambient Online Fire compilation.
Onward to the second and third rows, where we’ll actually get to stuff that directly makes noises! And has orange knobs!
But first: on the left we see a Pittsburgh Modular Lifeforms Dynamic Impulse Filter. This is a modern non-vactrol LPG with a classic design, with a mode switch that lets you select whether it’s going to act as a VCA, an LPG, or a lowpass filter. Its response to triggers is not to my liking, but it works well controlled manually or via CV. It has a uniquely woody tone, and controls that make it handy in any mode. 4/5.
Filters, particularly VCFs (voltage-controlled filters) are important building blocks in synthesizers. (Subtractive synthesis, the most common technique, is performed by pairing a harmonically rich simple oscillator with a filter.)
Filters reduce frequencies in part of the spectrum, while optionally emphasizing it in others (called resonance).
A lowpass filter allows lower frequencies to pass through while quieting higher ones; a highpass filter does the opposite. A bandpass filter allows only a narrow band of frequencies to pass through freely, while a notch filter reduces only a narrow band of frequencies. A multimode filter typically will either switch between these or provide all of them simultaneously.
Different circuit designs have widely different characteristics in terms of slope, resonance, stability, phase characteristics and so on. Many designs will self-oscillate when the resonance is high enough, producing very pure tones even without input.
Equalizers (EQ) and tone controls are an especially gentle type of gentle filter.
Next is the Doepfer A-196 PLL (phase-locked loop). This is a strange beast! Given incoming signal (audio rate or slower), it attempts to match the frequency and create its own set of pulses. It does this by constantly measuring whether it’s ahead or behind, and feeding back a signal to itself to make adjustments… but depending on settings, the material it’s tracking, and how much you intentionally confuse it, it can be joyfully terrible at its job. The open nature of this module lets you do all kinds of bizarre tricks with it. One of my favorites is patching in a different oscillator instead of its own — perhaps one that’s trying to modulate itself and therefore can’t properly track pitch without extra help. 4/5 (it’s pretty situational, and there’s sometimes a razor-thin margin of error between good tracking and garbage).
The leftmost orange-knobbed module is the Hertz Donut mk2 by The Harvestman (now called Industrial Music Electronics). It’s a proudly digital take on the Buchla 259-style complex oscillator. It’s not a very clean sound to start with, and includes phase feedback as an option on its modulation bus, a harsh “discontinuity” control rather than a typical waveshaper, as well as an XOR output which is a rough sort of ring modulation. But FM with it is super-easy and the thing really can be beautiful, especially through an LPG. 4.9/5! (If it remembered its state when powered down that’d be perfect.)
An oscillator generates a signal that repeatedly fluctuates between positive and negative voltages. This is the most important building block in any synthesizer. (Cue people arguing that the filter is more important, but I say, not without something to filter!)
A VCO is a voltage-controlled oscillator, which is the kind most relevant to us in modular synths. VCOs use the 1V/octave standard for frequency control and typically work at audio rates (20 to 20,000 cycles per second, or Hertz (Hz)) just like sound waves.
If it’s slower than that, it’s an LFO — low frequency oscillator — and rather than making sound, it will control or modulate something else. Some LFOs can synchronize to a clock signal to stay on rhythm; many VCOs also can synchronize, which can have interesting effects on the sound. (It’s rare for VCOs to be much faster than audio rate, but there are specialized uses for it.)
The shape (or waveform) produced by the oscillator determines the sound (or timbre, which annoyingly is pronounced “tam-ber”). There are a few common ones in synthesis because they’re easy for analog circuits or very simple code to produce — triangle, sawtooth, pulse/square, and sine — but some oscillators can create extremely complex shapes.
Complex oscillator is a term for a specific configuration as used in the Buchla 259 and many imitators. It consists of a pair of oscillators that can track together and modulate each other through FM and in other ways, frequently using a “mod bus” to assign and control the amounts. The “primary” oscillator also includes a waveshaper or wavefolder which further increases the harmonic complexity. This is the quintessential West Coast design, rarely seen outside of modular synthesizers. (Some people use “complex oscillator” in a more generic adjectival sense, but this is discouraged.)
Generally, analog oscillators are prized for a sort of mythic “warmth” and other subtle qualities, while digital oscillators are much more diverse in terms of shapes they can generate as well as potentially more precise (or imprecise in specific ways). A common type of digital oscillator is the wavetable, which keeps shapes in memory and can smoothly change between them. Other digital oscillators are based on mathematical models and algorithms computed in real time.
FM, frequency modulation, is a synthesis method where the output of one oscillator modifies the frequency of another oscillator. Slow FM is just vibrato, but at audio rates the result is instead a change in timbre, which can be brassy or bell-like or incredibly noisy depending on the frequency ratio between the two oscillators. Many non-modular synths like the famous Yamaha DX7 actually use phase modulation (PM) which is similar but simpler in some ways. In the modular world, one deals with exponential vs. linear FM, thru-zero and other complexities having mostly to do with keeping things in tune while being able to shift the timbre at will.
There’s also AM or amplitude modulation, which is simply controlling a VCA with a second oscillator harmonically related to the first but has somewhat similar timbral effects; RM or ring modulation, and filter FM which modulates the cutoff frequency of a filter at audio rates, producing a combination of amplitude and phase modulation.
(An aside about my aside: some people love to “debate” analog vs. digital audio. This is less common among modular synth types, probably because we know it’s like arguing whether a wrench is better than a screwdriver. If you use the most practical and appropriate technology for the function at hand, you’re probably going to have both.)
The next orange knobbo is The Harvestman Kermit, after Kermit Washington, the One Punch Man of basketball. It was designed as a dual LFO based on a small wavetable, but it will also run at VCO rates, where it’s very noisy and fizzy and unstable in a beautifully disastrous way. Something about it makes it especially well suited to amplitude modulation. It would benefit from fine-tuning knobs, normal-sized knobs for the modulation inputs, and remembering button states on shutdown. The clock/pitch following mode is a sloppy mess. But the sound is unbeatable, and it works very nicely for LFO purposes. 4/5.
Then we have The Harvestman Tyme Sefari, named for a time travel company in a Ray Bradbury story. It’s a lo-fi digital audio buffer that can capture and play back audio — a very flexible sampler or a delay/echo depending on how you configure it. Like Chronoblob, it has an open feedback loop that adds flexibility. But unlike Chronoblob, the sound just can’t avoid being grungy and that doesn’t always suit. It’s also pretty large, especially with its expander module. There’s a firmware update supposed to be coming soon which should make it less glitchy, and I’m pretty much waiting to see what I think of that before letting it go for something else. 3.5/5.
To its right is its expansion module, A Sound Of Thunder (which is the title of that Bradbury tale). This adds a second channel to the TS which can be used for stereo or other nefarious purposes. There’s no mix control though. It also adds some marginally useful options to make the sound even worse or to shift the pitch. It’s overly large for what it does. 2.5/5.
Getting back to white knobs again, we have the Antimatter Audio Crossfold. This is a nice wavefolder with two inputs, which lets you crossfade between the two, control the folding amount two different ways, and fade between the original (or mixed) and folded signals. This combination of features gives it some great sonic versatility. 5/5.
Here comes Bastl Cinnamon, a multimode filter. It’s pretty straightforward and sounds good, with some switches to make it rougher. I won it in a charity auction and it was supposed to have been the aluminum panel version, not wood — which is weirdly thick and doesn’t fit well, and makes the text labels hard to read. Still 4/5.
Last are a couple of passive infrastucture bits. The Doepfer A-180-9 Multicore lets me make 14 connections between this rack and the case on the other side of my desk through a pair of Cat-6 network cables and very compact panels. (I am in the habit of keeping two lines to my audio interface, which on the other side are stereo outputs of one of my FX pedals.) Unfortunately I still had to run a separate ground wire between the cases to eliminate hum. If the two network jacks were both at either the top or bottom — and better yet, if they had a rear option — it’d be a little less unwieldy. 3.5/5.
The last tiny module with a row of nothing but jacks is a Bastl Multiple. It passively connects all 9 jacks together, and you can configure it by snipping wires on the back. I divided this one into (2, 2, 2, 3) just to have a handy way to patch into 3 inputs and an output on the back of my audio interface. Cheap and useful, 5/5.
The bottom row of the rack has just 5 modules, but the first one’s a doozy. It’s a beta test version of the Synthesis Technology E370 Quad Morphing VCO. It is the absolute monarch of wavetables, with four independent or coordinated VCOs. Borderline overkill.
My main gripe about it is that dynamic linear FM is quite tricky to set up, compared to the ease of the Hertz Donut. I believe it could be solved with a software tweak (a menu option for a DC blocking filter on the FM input while in linear modes) but can’t convince the DSP guy to try it, so it is what it is. However, all the other audio-rate modulation you can do to the thing is fantastic — the internal 2-Op FM model, exponential FM, PM, AM, wavetable morphing, wavefolding — and you can create FM wavetables in the first place. And the cloud mode is stupefyingly good. So it’s a 5/5 for sure.
The next module with a screen is Dave Jones O’Tool+. It’s a dual-trace oscilloscope, voltmeter, frequency meter, tuner, spectrum analyzer, and metronome. It’s invaluable for learning new modules, setting up tricky patches, solving problems and giving you answers that your ears don’t. 5/5.
A patch is a “program” of modules and connections. It can refer to everything you’ve got set up at any given time or a functional subset; it can be a general term (a bass patch, a Karplus-Strong patch, a feedback patch) or refer to exact settings. The term is sometimes used outside the modular realm it’s also used to refer to a synth program or a configuration of gear. Some people diagram them or photograph them; I sometimes take general notes.
A patch programmable module is one that takes on different behaviors depending on what’s patched into it — like the function generators I mentioned in the last post which can generate envelopes or LFOs, delay a gate signal, filter audio, smooth a stepped signal, and so on. Multifunction modules, on the other hand, require changing between different mode to determine the behavior. Of course, there are modules blur that line.
The plain-looking module with the eight knobs is Epoch Modular’s Twinpeak filter. This has two inputs that can be mixed, and a knob to fade between a single lowpass filter mode and a dual bandpass. At the highest resonance settings it doesn’t continuously self-oscillate, but a trigger into the input will make it ring in a lovely percussive way for a second or two. I am not a big filter connoisseur since I lean more toward non-subtractive synthesis, but this one has proven itself to be pretty cool. 4/5 (a mix CV input would have been nice).
Frap Tools 321 is a three-channel offset and attenuverter, with a pair of mix outputs (one mixes everything, the other mixes only the channels where you haven’t patched the outputs). Very useful for getting signals to the appropriate levels. I’m not in love with the tiny black switches on the black panel with tinier labels, but it does the job. 3.5/5.
Finally there’s the S********k S***r P***r G***n. It’s a power supply module. Some time after I bought it, the owner of the company revealed himself as a misogynist alt-right toolbag and proud trust fund baby who, he says, doesn’t need any of us. So I covered his logo with sparkly star stickers and never did business with him again. The power supply works okay.
More happily, behind the panels I’ve got a Genus Modu Low Impedance Bus Board (LIBB) helping to distribute that power and keep it clean.
And that’s my rack! Part 3 will cover the top row of my TipTop Mantis case, which is full of fun things that need explanation. 😉
And here’s the bit where I get into what’s in my modular synth cases, and what I like and don’t about each bit. I’m going to take it slow, and try to keep things as interesting as I can for people who are new to synths and for more experienced types curious about what I’m using and what I think of it. As a result, this is going to take a few posts.
Let’s start with the rack on the left side of my desk. It’s a desktop 19″ rack stand, of the kind you could fill with servers and backup drives, or with mixers and effects. At the bottom I’ve left one space empty for cable clearance, and then a 1U power switch bank — handy for devices without their own switches, and also for rebooting the router and cable modem without crawling under the desk.
At the top, there’s this:
Left: A “monitor lizard” who lost his natural habitat back when I went from a CRT to LCD.
Middle: CV.OCD by Sixty Four Pixels — a very customizable MIDI converter with 4 CV and 12 gate outputs. With this I can sequence notes, other gates, and synchronize from the computer to modular gear. I have mine set up so MIDI channel 1 outputs pitch, velocity, gate and an extra trigger; channel 2 and 3 each have pitch and gate; channel 10 assigns five specific notes to gate outputs, and there are three clock sync signals at different divisions.
A quick bit about how Eurorack modular synths communicate: they don’t use MIDI, they use analog control voltages (CV). Each patch cable carries one signal. Signals have no intrinsic meaning and are left to modules to interpret, but there are some typical signal types.
Frequency (pitch) has a standard of one volt per octave (“V/OCT“).
Gates, which determine whether a note is held or some other temporary event is active, are either “low” (0V) or “high” (some arbitrary positive voltage).
Triggers are simply short gates and the important part is the rising edge where they jump quickly from low to high.
Clocks are triggers that repeat to define timing.
Audio is a voltage that fluctuates quickly enough to be audible if connected to a speaker.
Everything else is probably modulation of some sort, though a fixed steady voltage is often called a reference or offset.
These signals are mostly interchangeable, with varying standards and consequences — discovering these is part of the fun of modular.
Right: The thing with the eye is a Bleep Labs Thingamagoop 3000. It’s a weird sound generating toy with a “LEDacle” that can blink in different patterns and speeds, and a light-sensing eye that responds to it (or other changes in light and shadow). Good for drones and weird warbly noises, I don’t use it often but it’s fun to play with. It can generate and respond to CVs too, but it’s much easier to just use it standalone and only tap its audio output.
Bottom: Focusrite Saffire Pro 40. This is how I get audio in and out of my computer. 8 analog input channels, some output channels, plus digital I/O that I’m not using, with easily accessible level and monitoring controls on the front. Perfect for my needs, except it’s Firewire rather than USB and initial setup was kind of a fight.
My top row of modules starts with Manhattan Analog DTA on left. This one was a prototype unit I bought directly from the maker. It’s two single channel VCAs in series, plus an extra drive stage to add some saturation and weight. Not the controls I expected (which would have been a manual bias as well as CV level) but still useful. Shame it’s AC-coupled. I’d rate it a 3/5 with no rancor; it’s not exciting but it does its job pretty well.
A VCA, voltage controlled amplifier (or voltage controlled attenuator) controls the level of one signal using another signal — an automated volume control. Typically you use this to shape the dynamics of a note using an envelope (a signal that responds to a gate with a voltage that rises, sustains and falls according to timing you set). But there are dozens of other uses, and a cliche phrase “you can never have too many VCAs.”
An attenuator is just something that brings the voltage closer to zero, but this is vitally important in modular. An attenuverter can also flip it between positive and negative. An amplifier pushes non-zero voltages farther from zero. All of these are multipliers — attenuation is multiplying by a value between 0 and 1, attenuversion multiplies by a value between -1 and 1, and amplification multiplies by a value higher than 1.
This brings up unipolar vs bipolar signals — which is simply whether negative voltages are expected or ignored. Audio is bipolar, but the control input on a VCA is typically unipolar — send it a negative voltage and it remains fully silent.
But there arebipolar VCAs which invert the incoming voltage if the control input is negative. These may be called “four-quadrant multipliers” or “ring modulators” or “balanced modulators” because apparently one term for the same thing wasn’t enough.
AC-coupled means it responds fully only to audio signals; any signal that changes too slowly will fall to zero. There are some technical reasons why one might want this, but usually DC-coupled is preferable since you can manipulate non-audio signals with it.
The second module is Instruo tanh, which has three channels of smooth saturation/limiting of audio or control signals. This can give audio a bit more of a push or “warmth” depending on levels and usage, can be used to keep feedback somewhat under control, or can be used to give extra curvature and interest to control signals. I like running envelopes through it to give them a sort of “sticky” feel (words fail a little). 4/5; those mini knobs are tolerable but not lovable and to really help with feedback control it needs an attenuator afterwards, and I feel like two channels with attenuation would have been nicer than three without.
Next in the line is Rabid Elephant Natural Gate, the holy grail of LPGs. The sound is gorgeous, the panel finish and art are gorgeous, even the box it came in is gorgeous. It’s extremely controllable and playable, with easily tweaked manual “open” sliders as well as decay times and a 3-way response curve switch. It also has a tendency to get louder if you trigger it rapidly, which can intensify the drama. I had the chance to try it at KnobCon Six, and bought one within minutes of the release announcement. Since then the demand has skyrocketed and the price has increased significantly due to the need to switch to a different contract manufacturer. But it’s soooo good. 5/5!
An LPG or lowpass gate is related to VCAs, but as the control signal decreases, the higher frequencies (treble) go quieter more rapidly. This can give more natural dynamics and is favored in West Coast synthesis.
VCAs respond immediately to changes in control voltage, but LPGs close (go quiet) more gradually than they open. A quick trigger to a VCA would let through a “beep”, but the same trigger to an LPG would give a natural, percussive “ping” or “strike.” This is such a common usage that some people forget you can use an envelope with an LPG just as with a VCA.
Classic LPGs use an electronic part called a vactrol, which were originally made using toxic materials. The EU has imposed strict limits on them in recent years. They also vary a lot in behavior and have to be hand-picked for desirable response. It’s possible to make vactrols using greener materials, but overall they seem to be falling out of favor, replaced by other circuits or digital emulation.
Soundmachines LS-1 Lightstrip: a handy touch controller that my spouse bought me last year. It will generate both a gate and a voltage according to where you tap or slide your finger, can hold the last touched level, and it can record and loop a few seconds of movements. Run it through a scale quantizer and you can use it like a micro keyboard! 4/5; sometimes the hold or record modes activate when you don’t expect, or don’t when you do expect.
A quantizer takes a signal and “rounds” it to match the nearest note value. Some round to the nearest 1/12 of a volt, while others let you choose between different scales or define your own. It’s like imposing frets onto a fretless instrument. This is great for random signals or imprecise controllers, and can be fun when sliding between notes.
Make Noise Contour is the aluminum one with the vertical row of four white-capped knobs. It’s a basic ARSR envelope generator similar to Moog designs, with adjustable response curve. The first envelope I tend to reach for when patching the left rack, it’s just so friendly and easy to dial in. 4.5/5.
Envelopes are often described by various types of stages: A for “attack” (onsite or rise), “D” for decay (fall), “S” for sustain (hold steady while the gate is high), “R” for release (a separate final decay after a sustain), and “H” for hold (hold steady for a fixed time).
The most common envelope types are:
D: immediate rapid onset followed by an immediate decay, like a percussion instrument or plucked string, or a vactrol strike. Gate time is irrelevant, this envelope treats its input as a trigger. If another trigger is received while still decaying, behavior can vary from module to module.
AD: rise to maximum, followed immediately by decay to silence. Again, gate time is irrelevant, and the behavior when receiving a second trigger can vary from module to module.
AR (or ASR): rise to maximum, sustain while the gate is high, and release to silence. If the gate is released while still in the attack stage, immediately release.
Many AR envelopes are implemented by slewing an input signal. That is, if the input voltage rises, the output level rises more slowly. If it falls, the output level falls more slowly. If the input happens to be a gate, the result in an AR envelope. If it’s stepped voltage levels, the result is smooth voltage levels. If it’s audio, the result is filtered audio (or silence if your attack and release are too slow). Modules that do this (and also AD, using a separate trigger input) are often referred to as function generators, and typically have EOR (end of rise) and EOC (end of cycle) trigger outputs in order to chain and synchronize other events.
ADSR: rise to maximum, decay to a specified sustain level, hold while the gate is high, and release to silence. With a zero sustain level it can imitate an AD envelope, and with a maximum sustain level it imitates an AR envelope.
ARSR or ADSD: a simplified form of ADSR where the decay and release rates are the same.
Multistage envelopes can have multiple stages of various types, as can vector envelopes which define level over time with a series of X and Y coordinates. Even rare are “spring” and “bouncing ball” envelopes based on physics models.
ADSR is the classic East Coast envelope. AD and AR envelopes, and function generators, are generally associated with “West Coast” synthesis. AD envelopes typically have a loop switch which allows them to rise and fall continuously, taking the place of the LFO (low-frequency oscillator) which is more typically East Coast.
All this East/West stuff is largely an arbitrary historical distinction between how Robert Moog and Don Buchla designed their synths. While there’s some truth that certain design philosophies work together well, the “coast thing” should not be taken too seriously!
To its right is Make Noise Function, a function generator that also has a “hold” function that freezes its current level. Much like Contour, the knob ranges and response just make it super easy and “musical” feeling. 4.5/5.
And then WMD/SSF Mini Slew, another function generator. This one has more CV inputs and a built-in VCA — it’s cleverly arranged as an attenuverter for one of the module’s outputs, with a bipolar CV in jack. You can run audio through that CV in jack, and the module’s envelope will control its volume. But the response of the controls is much more fiddly than Function, the EOR/EOC outputs are a bit flaky, and unless the trigger is above about 6.5 volts, it won’t retrigger during the falling stage — which can be advantageous but it’s an awkward default. And for some reason it requires twice as much current from the power supply as Function. 3.5/5.
Make Noise ModDemix is next. This is a pair of bipolar VCAs with kind of a nonlinear twist right around zero that gives it a little extra spice. There’s also some normalling which straddles the line between confusing and useful. I should use this more because I often forget it’s there — maybe if I stuck it over on the left side between DTA and Natural Gate it wouldn’t sneak away from me. 4/5
Normalled connections are default connections that are interrupted when you plug something into an input. For instance, on the DTA, if you don’t plug anything into a CV input, a constant positive voltage is normalled there instead so you can use the knob as a manual volume control. The same is true of the audio inputs on Natural Gate, so you can use it as a D envelope generator when it’s not processing audio.
The module with the cute pink blob is Alright Devices Chronoblob, a digital delay effect. I have a lot of delays in software, but it’s good to have at least one in the modular system as well. What makes this module special is (A) a sync input which lets you lock delays to the beat, (B) the choice of whether to change delay time with a smooth tape-like pitch shift or a clean crossfade that lets you bounce delays all over the place to create interesting patterns, and (C) send and return jacks for the feedback loop which let you affect the echoes or do some other clever hackery. 4.5/5 (a level input knob would have been swell and a clean feedback limiter would have been ultra).
Ending the first row is a Doepfer A-138m matrix mixer. This has four inputs on rows, four outputs on columns, 16 knobs to assign them, a switch to choose bipolar or unipolar control of each column, and the top row is normalled to a constant voltage. It can act as a manually controlled voltage source, independent attenuverters or mixers, a handy way to mix sources in stereo, control feedback, rearrange the signal flow of other modules patched into it, and even can be used for sequencing by feeding it combinations of gates. 4.5/5 (higher frequencies can leak through just a little even when the knobs are turned down fully).
A sequencer stores sets of voltages and/or gates as discrete steps, and can play them back synchronized to an internal or external clock. Sequencer designs vary widely to cover many different needs and styles of composition; some have multiple channels, are rhythm-oriented, can rearrange the step order, and so on. Since musical pitch is a primary use for sequencers, many have built-in quantizers.
So that’s what’s in my first row. Stayed tuned for the other four and the pedalboard & miscellaneous stuff… and then some words about the logic of module arrangement, why I chose one module over another, (unsponsored) recommendations, various sequencing methods I use, and a lot of other blathering. 🙂
Modular synthesizers look, at first glance, needlessly complicated and difficult. One might wonder: why not just use a computer and plugins, or “normal” keyboard synths? That’s certainly what I thought when I first saw Eurorack gear in YouTube videos a few years ago.
But individually, each piece is relatively simple on its own — if not in function, at least in concept or purpose. All but the most exotic modules can be thought of as a single building block or a group of related building blocks. And we tend to acquire them by ones or twos, giving ourselves time to get familiar with each individually.
System size can vary from just a couple of modules in a “lunchbox” style case or DIY with cardboard, to modest portable rigs, moderate home studios, or intimidating walls of gear. Some people will keep every module they buy or build, while plenty of us trade frequently to keep it fresh or to pursue the perfect setup.
Modular synth types often call this “the journey” — the gradual process of researching, building, learning, and creating with one’s own unique synthesizer(s). You will see the phrase “my modular journey” all over message boards and interviews, and it feels apt.
Here are the highlights of my journey:
70s: I grew up wearing out my dad’s 8-track tapes of Isao Tomita and Wendy Carlos, playing with casette recorders and a Magnus chord organ.
80s: my first synth was a beat-up Micromoog, but like almost everyone else at the time, I soon craved the new wave of digital synths with polyphony, MIDI, cheesy electric piano presets, etc. Also a science teacher gave me his old oscilloscope.
90s: a little bit of messing around with old MIDI gear and computers, but nothing too serious. I have maybe a dozen recordings from this era and they’re generally not good.
early oughts: my brother introduced me to DAWs and VSTs. I loved it. I recorded several albums, first as Lotus Wire and then Falls A Star. (If you really feel the need to check that out, I currently feel like Underlands, Dian Skies and The Signal hold up for the most part, and bits of Diffusion.)
2016-2017: a new band name and a “song a week” project that went a little nuts. I now think of that period as my internship.
Fall 2016. A DIY bamboo box and a few Mutable Instruments modules from a charity auction and holiday sale, to accompany my Arturia MicroBrute. And terrible cables.
Spring 2017. An experimental sound laboratory.
Late summer 2017. I’d started to find a new focus in my music, and chose my gear to favor “West Coast” synthesis and wavetables to suit it.
Winter 2017-2018. I was honored to beta test (and keep) a SynthTech E370 and Mutable Instruments Plaits, Stages and Marbles, so I needed a second case to make room.
At this point I had really “found my sound,” so I dropped the song-a-week thing and started recording much better albums. You’re welcome. （＾ｖ＾）
Summer 2018. Went through several iterations of sequencing modules as well as effects in both Eurorack and pedal format. Some of my albums have used little to no MIDI sequencing, but combinations of algorithmic and simple sequencers as well as manually controlled drones.
Fall 2018. I declared my modular system to be at “version 1.0” with the notion the pace of changes would slow greatly, and I’d soon finish the pedalboard with a couple more pieces of gear.
Winter 2018. Since then I’ve sold/traded 8 modules and a pedal for 6 modules, two pedals and a little sequencer. I’ll call the current state “version 1.1,” and will post a tour of it here soon. I don’t doubt it will mutate a little bit further
I realize I did not yet answer the “why” part of the question at the beginning. For that, I recommend the YouTube series Why To Modular by Knobs. All of Knobs’ videos are just dreamy, but this series does a fine job talking about part of why nerds like me find modular synths so compelling.
For me, it’s been about access to sounds and techniques that I wasn’t getting in software, and the removal of a lot of artificial boundaries and habits that most musicians who only use VST plugins aren’t even aware of. I have learned a ton about synthesis techniques and found immense satisfaction in exploring the possibilities, and as I’ve said, found “my sound” in the process.
And yes, there are modular synthesizers available in software now, including VCV Rack and Softube Modular which not only imitate Eurorack format, but include officially licensed software ports and emulations of real modules. But the experience isn’t the same, and that’s important. These are musical instruments, not scientific instruments, and the feel matters. To paraphrase someone or other, it’s like the difference between playing a video game about mountain climbing, vs. actually doing it.
As of today I’ve been around the sun 47 times. Another year older, another three days wiser. Something like that.
Aside from sipping a free mocha, planning to have a nice dinner, and deleting automated well-wishes from websites I don’t remember ever signing up for, today I’m in the metaphorical cutting room, deciding which tracks I’ve recorded for Materials to throw carelessly on the floor. Over the holiday weekend I recorded 3 songs for it and 3 songs not for it, so that’s probably a sign I’m getting ready to move on to another project.
Art is a frequent conversational topic on the inconveniently-URL’d llllllll forum, aka Lines. What it is or isn’t, how we make it, why we make it, who we make it for, what if anything distinguishes success from failure, and so on — but mostly in a thought-provoking (if occasionally baffling) way rather than a tedious one.
Not for the first time I am contemplating my own music and how it relates to art, craft, entertainment, hobby, intention, expression, statement, experiment, etc.
First, what some other smart artists (smartists?) have said — no doubt taken out of context in many cases:
I don’t have messages in my pictures.
I don’t have anything to say in any picture. My only interest in photography is to see what something looks like as a photograph.
I have nothing to say, and I am saying it.
Value judgments are destructive to our proper business, which is curiosity and awareness.
The best reason to paint is that there is no reason to paint.
The fact I myself do not understand what my paintings mean while I am painting them does not imply that they are meaningless.
Let’s get a little crazy here.
If I paint something, I don’t want to have to explain what it is.
The world always seems brighter when you’ve just made something that wasn’t there before.
In my own words: I make music because I enjoy the process, because I am curious to find out what it will sound like, and because I enjoy the results.
There isn’t really a burning need to express specific ideas, emotions, messages or stories. Nor do I really set out to create a specific effect in the listener. Sometimes I have a theme in advance, sometimes it comes along the way, and sometimes I just reinterpret after the fact — but the theme is almost never the motive for making the music.
My “artist’s statement” for nearly all the music I’ve made in the past several years: I wanted to make music, and so I did it. Some would say that without intent, just creating for the sake of creating, means it’s craft rather than art. My answer:
(And also, I disagree. Not strenuously, but I disagree.)
At the same time, self-expression (as opposed to emotional expression or idea expression) is very much part of the process, affects the creative “experiment”, and determines what the music will sound like. Things that cannot be said, understood or fully recognized, can still be musicked. Failure is when the music doesn’t sound like me.
Failure — of the art, not the experiment — can also be when the music is too boring or meandering. It has to be entertaining, by my standards. To which, again, some people would say that means it’s entertainment, not art. I repeat: ¯\_(ツ)_/¯
While shrugging at people, some object to my use of the word “song” to describe non-vocal music, non-lyrical music, and/or music without formalized structure, or clearly defined Western style melody and harmony. Here you go: ¯\_(ツ)_/¯ I used to use “track,” but that’s an overloaded and technically incorrect word, and to me implies a fear of calling the thing music. So I’m (re)claiming “song.”
I will wrap this up before my arms get tired from shrugging. By the way, over the course of writing this, working at my day job and reviewing those songs, I decided that 11 out of 13 get to stay, for a total runtime of 1:05:46 (before a little more editing work) and I don’t really need to record another song to include on the album. Next comes the mastering and artwork phases!
When I create songs, I do it in a single session whenever possible, or two if necessary. From the point where experimenting/jamming crosses my “I have to make this a song” threshold to when I put the headphones down and walk away, it is rarely more than 4-5 hours.
Usually the first thing I say to myself when I have done so is “I’m not sure about this one.” It’s too boring, it’s too harsh, it’s too weird, it’ll never work with the rest of the album…
The next day when I listen to it? It’s fine!
It’s not that I have some kind of house elf who comes in and fixes my recordings while I’m off sleeping or playing video games, it’s just my perception. (A) I’ve been listening to variations on the same thing for a few hours and am getting pretty jaded, vs. (B) I have fresh ears and am listening to a 4-9 minute song in the context of other things I’ve recorded recently.
Not everything I record gets released. Turning songs into an album usually requires filtering a few things out to make it a stronger whole. Some of them are weaker, some of them just don’t really fit. I currently have 16 songs in a folder called “other unreleased” and another 6 simply called “no.”
This method of working quickly has been really helpful to me. Through 2016-2017 I recorded over 380 songs this way. After several months, I found myself consciously critiquing my overall output and realizing that some things worked and others didn’t. Decades of scattershot music-making — trying to do almost everything that interests me, which is a lot — were brought into focus. After a few more months of refining both my gear and technique, I started recording albums again with this new focus.
Going back to make little tweaks and adjustments and additions to a song dozens of times didn’t really serve me so well. Many changes didn’t necessarily improve anything, just make it different, satisfying my ear fatigue. More importantly, those changes only affected a single song — what I needed was to improve my whole practice. I stopped arranging the pine needles in my forest just so when I realized I preferred oaks anyway.
It would be nice to tell the story that I went to this single-session thing as part of a grand plan. Really, the single-session thing was driven by my transition from 100% software music-making to a mixed approach — and some faulty, unreliable little desktop synths I was trying to work with at the time — and the fact that using these synths meant taking up space on my desk that I needed for other things. It was easier to just get it done and put it away, than to keep it set up and running for multiple days while hoping nothing would crash or get accidentally unplugged!
I stuck with these habits — to me it fits perfectly with the transitory nature of patching a modular synthesizer. About which I’ll just throw out another quote:
“I think the modular sound has less to do with timbre and more to do with the fact that when people are patching a modular, they seem to be less interested in micro-management as a music-making process. The extreme magnification of musical event time and pitch provided by modern DAWs seems to curate what people believe to be perfect music through the aid of a machine.
Music made with the modular system is, in my opinion, a pure and interesting collaboration between human and machine. It displays well the beauty and the blemish in both (human and machine)… it might be less perfect by judgement of mainstream music taste, but perhaps more exciting to those of us seeking a deeper connection to the music.”
My process is this: I set up the entire song: sound design, composition, sequencing and/or performance plan, mixing, effects, all of it. And then I record it “live” to a stereo channel. If I feel it’s a good take, that’s it — it’s committed. I take notes to satisfy my later curiosity, shut it down and unpatch the modular. There’s no multitracking, no going back and making small changes or revisiting mixing decisions. The only editing possible from that point is on the “finished” mix.
Sometimes a lot does happen in that editing, but generally it falls into “mastering” enhancement and cleanup, or bold-stroke creative changes — not revisiting past decisions. Always moving forward, no going back.
Regret that I can’t make those changes is rare and minor at most. For all of the fear that some people have of working with a synthesizer that can’t save presets, this is never a thing that has bothered me about modular synths. Instead of saving and loading sounds with perfect recall, I remember general techniques that will lead to new creations in the future. Always moving forward!
As the sidebar currently says, my current musical project is an album called Materials. It’s the kind of music that I have been making — the dark side of ambient, spooky, unsettling, etc. — but it’s also a study of Mutable Instruments Rings. Rings, a physical modeling resonator, is one of the most popular Eurorack modules (#4 if you can trust ModularGrid) and with good reason.
The easiest way to use Rings is to just send it a pitch and optionally a trigger signal, and it produces a lovely plucked string or struck bar or membrane — sounding like metal, glass, wood, etc. Guitars, xylophones, some types of drums and so on are in easy reach. But its ease of use, popularity and beauty have made it something of a cliche, and there’s a backlash against its easily recognizable sounds.
Like any good backlash, there’s a counter-backlash. The module’s designer and some musicians such as Billy Gomberg point out you can think of it more as a sort of filter/reverb. Feed any audio source into Rings (including itself) and now instead of tapping those strings and plates, you’re bowing them, rubbing them, blowing air over them, vibrating them sympathetically… really it’s entire worlds of realistic and impossible materials for musical manipulation.
Rings was the module that got me into Eurorack in the first place, and I was doing this “fancy” stuff on my first day with it. To me it’s what makes Rings so good.
Early in October I read too many “it always sounds the same” posts and snapped. And by “snapped” I mean “decided to record an album that proves them wrong.”
The challenge has been holding back from centering other stuff that I really like — but coming up with myriad ways to use Rings that don’t “sound like Rings” has been fun and easy. I have a whole list of things I could try that I will probably never get around to. I even wound up trading a couple of less favored modules for a second Rings — they work really well together.
Overall, I feel like the best partner for a Rings is Plaits, Mutable’s versatile “macro oscillator” that incorporates many different synthesis methods. But when you have a whole modular synth to work with, plus field recordings, software synths, samples of acoustic instruments, and so on there is really no limit.
Yesterday’s effort used Rhythmic Robot Hurdy-Gurdy as the sound source for the first Rings, which then fed the second Rings. Strings vibrating strings vibrating strings! The gurdy and both resonators were mixed and run through reverb and a touch of distortion and filtering. Here is the result.
Doesn’t really sound like a guitar or xylophone, does it?
Maybe you’ve never wondered how I come up with song titles, but there is a thread on Ambient Online about that question, and reading it today coincided with an update from one of my favorite sources of name inspiration.
I’m sure I’ll write plenty later about my process(es) for creating music, but this is what happens after. Or during. Or before!
Sometimes, songs name themselves. I’ll be finishing it up and stop to listen through, about to record, and some impression will strike me and lead to a name. Or not, and I might just pick a temporary name so I can save the project file, and get around to a real name later.
Sometimes I have a theme in mind for the album, and that helps me choose a name. Although in the case of Nereus, I already had most of the album done when the theme struck me, and I wound up renaming several songs (some of them, several times.) I had to keep a chart for a while so I wouldn’t lose track.
When all else fails, I consult my list. Whenever I invent or find a turn of phrase that I think has a remote chance of working — or when my spouse suggests it — I put it on my “Song Names” note in Simplenote. Most of the things on this list will never be used, and sometimes I cull the least interesting and least likely. But sometimes going over the list and finding these goofy phrases will trigger a better idea.
Also contributing to this list: the neural network antics featured on AI Weirdness. During my period of prolific exploration in 2016-2017, I leaned on it quite heavily, giving such fantastic titles as “Zuby Glong,” “Crab Water,” and “Corcaunitiol.” I haven’t used it so much on my album releases, but again, sometimes those random strings trigger some ideas.
Here are some great bits from today’s blog post over there:

How could one fail to be inspired by such poetry?
(I really like “Zuby Glong” though.)
Another great source of names, phrases, and inspiration is Botnik Predictive Writer. Being both themed and somewhat human-directed, it tends to make actual coherent phrases.
With Salt On Your Arms Of This Debris is a World Built A Small Change of Wavelength
(I may actually use one or all of these.)
Really though, coming up with names is not the hard part. I feel like, if you’re creative enough to do all of the other stuff then you should have no trouble with…
