Voltage Modular VM900 Ratcheting
video upload by boxoftextures
"Well, been playing almost nonstop in Voltage Modular with the VM900 module collection, basically a pile of Moog-style modules from Cherry Audio. So what does one do with a Moog modular? For my part I'd head straight for the 960 sequencer. And what does one do once you've gotten that working? Well, ratcheting is the next step, of course. Voltage Modular does have a number of ratcheting modules, and the clocks to drive them, but I wanted to do it analog-style, not any of this new-fangled modern digital stuff (ignoring for the moment that this is all in computer software, of course). Was pretty satisfying to get it working. To be totally transparent the ratcheting aspect of the patch was not my original design. Many years ago Roger Arrick of synthesizers.com did a demo video of his Q960 sequencer module and how to use the 962 switch and an oscillator to make the ratcheting pulses. That video has been in the back of my mind for years, and in my bookmarks, but I don't quite have the Euro hardware for it and there hasn't really been a 960-style sequencer in Voltage Modular. Until now, that is.
So I took Arrick's basic concept, which is pretty ingenious, and adapted it to the slightly different modules in Voltage Modular. Turns out doing ratcheting in the analog realm is a lot more work than using a digital ratcheting module. Surprise! Was incredibly happy to get it working.
In this setup I'm using Row A of the sequencer for the notes and Row B for voltages used to generate the extra triggers. And it's great fun to play with the knobs and change the number of ratchets and which notes in the sequence get them. However, that's a lot of manual labor, and I wanted to take it a step further and make the ratchets happen on their own at random steps. That is not in this video, alas, but fear not, I've been able to patch it up and that's what the next, more in-depth video will be about. Still done entirely in the analog module realm though, for authenticity's sake."

"Fully functional (serviced recently) and cosmetically in very good condition bar some scratches on the top, all the pots and switches feel fantastic. This Lambda has been modified, these modifications substantially improve the depth to programming the lambda and greatly increases the range of sounds you can get out of it, here is a list of all the mods:
- Individual volume control for each preset (the knob under each switch)
- "Tone" controls (terrible 1 pole RC LPF) have been replaced with a resonant AS3350 lowpass & bandpass filter with cutoff and resonance pots (the switch at the end of the row of knobs changes between them)
This new filter sounds really, really fantastic.
- Both the sections (percussion & ensemble) go through the new filter and into the ensemble, as the fake "stereo" on this synth is the percussion through the left and ensemble through the right, this makes the synth mono, and they only go through the ensemble chorus channel (percussion chorus button does nothing).
- Percussion level slider is now dry/wet mix for the chorus, ensemble level slider is master volume.
- L & R Output jacks are now Chorus External input jacks
- Headphone jack is now filter cutoff CV input
- The trigger out has been changed to a positive gate signal (0V normal and goes high when pressing a key, normally it is inverse to this and incompatible with most things as a result)"

"I bought this new in 1996. It has almost never been used. Everything works. However, I have not done any O.S. upgrades on this unit, and I'm pretty sure it could use one. The current O.S. is 3.00. For me, the coolest things about this synth is the arpeggiator (it does arpeggios that I have never seen on any other synth), the real-time knobs (very analog-like control), and the awesome keyboard which is (as far as I remember) the same as the one used in the Roland A-70 controller, which is semi-weighted and feels amazing. The black keys have an almost wood-like feel."
