Patchable 0007

It is common knowledge that a great number of modular users suffer from Gear Acquisition Syndrome.  Sometimes it is about finding the modules that work for you but often it is driven by a need for the newest, coolest most baddass feature set available.  With the holidays fast approaching, it is a fine time to pause and remember what you have. Sure, there are plenty of Black Friday deals out there, but what if that neglected simple VCO you have could do more?

The Challenge

Get the most from a simple VCO possible.  Create a patch using only a single VCO as the only sound source and create as many voices as you can without multi-tracking.

Many simple VCOs offer multiple simultaneous wave outputs.  In this Patchable, you are encouraged to take full advantage of these.  Create bass, melody, percussion, and/or noise. Gate it all differently.  Mix waves, divide or multiply, filter, delay, frequency shift, chop them up or make them drone.  What you do with the waves after the VCO is entirely up to you and whatever you want to use. The VCO you use should really only have a single oscillator.  For example, STO, Spectrum, Dixie, VCOb

Some restrictions apply to this challenge:

  • The VCO you use should only have a single oscillator.
  • Do not use complex VCOs, this includes but is not limited to:
    • Modeling VCO (Plaits, Braids, Rings, etc)
    • Wavetable VCO (E352, Piston Honda, SWN, etc)
    • Dual, triple, quad or oct VCOs (DPO, Cs-L, Antiphon, etc)
    • Harmonic oscillators (Verbos HO, Stages, Odessa, etc)
    • Drum modules (no trig inputs, BIA, Fracture, etc)
  • Full voice VCOs are discouraged, but if you must, try to only use it in the manner of a single, simple VCO.  M32, 0-Coast are acceptable examples because there are single VCO.

Keep in mind, this is about getting the most from a simple VCO.  It is not meant to exclude those that do not have a simple VCO.  If you would like to participate but do not have a simple VCO, try your best to stick to the rules.  For example, if all you have is a DPO, use only one side of the DPO.



  1. Create an original piece of music following the above challenge.
  2. Include the suffix PATCHABLE-0007 in the track title.  A completed track title would look like this: Spiral Vortex PATCHABLE-0007 (where “Spiral Vortex” is your song name).
  3. Upload your track to soundcloud by end of day, Friday December 6th.
  4. Include a link to your track and patch notes in the comments below.

It isn’t my best work, but its done lol Live, one take, no overdubs… all from a single simple oscillator. For this I used one simple oscillator on the Pittsburgh SV1. For the lead I’m playing the Pittsburgh KB1 and I’m going through the SV1’s normaled connections- various waveforms through the mixer, filter, ADSR’ed VCA through a Mutable Clouds clone to give it some more body then into a mixer module. Various things here and there were modulating stuff on the Clouds. (LFO, Pressure Points, etc) For the “meat ‘n badedas” of the challenge, I took the sine wave… Read more »

chris This track uses only the STO as a voice. The STO is sequenced by the Rene with both the shape out and sub octave out sent to the QPAS. The high pass of the qpas was sent to the Morphagene and the loop is played one octave down. The MATHs is has a slow rise and fall controlling the filter cutoff of the band pass filter on the QPAS. This is then run through the Mimeophon. The sine out and sub out are also run through the 12db and 6db channels of the lxd respectively. The top channel is… Read more »

chris I HAD TO DO 2 😛

This piece is using only the STO as a voice. The pitch is being controlled manually by the keystep. It is run through the Morphagene with time lag accumulation varying between pitched up and octave and no pitch change. It is then run through mimeophon to create additional layers of the sound.

TEMPI is running with two channels shifting to the level of the QPAS which is receiving the sub octave out on the STO.

Singular Madness – G.A.S. – Patchable-0007 – Only a single VCO was used to create this track – the AJH Vintage VCO. All layers recorded simultaneously in real time. The bass is a subharmonic of the triangle waveform, generated via Joranalogue Contour 1 and a voltage controlled switch, routed through an AJH V-Shape to round then distort the resulting subdivided wave, then through the MiniMod VCF & VCA, then mangled by Clouds and Mimeophon both with modulation by Voltage Block and Marbles. Pamela’s New Workout fired this voice’s envelopes via a slow probabilistic Euclidean sequence triggering half of Intellijel… Read more »


After I did the first satellite patch for the STO I decide to do a couple more variations of this. Think of it like in movies or shows where you have a general theme sound and then you hear it done multiple different ways.

I made the set which includes

They all have the same general sounds within them created by the STO but as each track progresses it becomes more distorted and broken which gives the different tracks totally different feelings and brings out different characteristics of the sounds.


*bugchaser* I used the Instruo Ts-L as the main voice (pulse, fold, & square). The sin went to the FM (linear). Envelops were generated from O_c piques (triggers came from Pamels New Workout). Intellijel quad VCA was used on the pulse and fold, the Pittsburgh modular dynamic impulse filter was used on the square. The output of the quad vca was fed into the 4ms DLD, which the feedback loop was sent to the QPAS. The dynamic impluse filter went to clouds. Rene was triggered by PNW, and the unquantized cv was sent to the v/oct in the Ts-L. LFOs… Read more »

Ethan James Startzman This was all done live and in one take with no looping or overdubs. I chose to use the Random Source Serge NTO (which is the simplest oscillator I have) being sequenced by the Stillson Hammer. A lot of control is provided by Tempi sending different clocks to different VCAs, and Tempi makes it very easy to change the clock division. Patch Notes: There are 5 streams of sound running out of the NTO. Stream 1: Variable wave folder output to a Make Noise Optomix. The Strike is being controlled by Maths channel 1 in Cycle Mode. This stream runs through an Eventide… Read more »
