Harmonic Transformer Plus
video upload by Randy Piscione
"In this video, I demonstrate the extenders for the Harmonic Transformer Eurorack module from PM Foundations. Each harmonic PCB has an SSI2131 VCO to generate the sine wave. Since this is a full-featured, very stable VCO, PM Foundations designed an easy to populate daughter card that would bring out the other functions."

"SPV-355 pitch-to-voltage synth in in very good condition. This unit allows you to route a control cv to the filter via the front panel inputs which make for more animated sequences. Decay had been modified to act also as release as on a Moog. Vital for sequencing. Otherwise the sound would stop dead when the sequencer gate ends. Cosmetically very good except for a paint flake at the top of the right rack ear."

"PPG Synthesizer 1002 for sale serviced an comes with fligtcase Had this for almost 6 years and serviced by Stefan Hubner who has a deep understanding of PPG systems. Some things to observe, one underside key broken but doesn't affect play..these are originals. Jacks for CV, Gate and filter modulation have been added and adjusted to 1V/oct. 'The mains wiring has been re-done according to current safety expectations (not to say standards) including a 'pig tail' cable with an IEC male plug for easier connection. CV and Gate were never standard on the 1002 so the ones having it were all more or less hacks, especially when it comes to oscillator CV. One would expect 1V/octave with 0 volts at a defined note usually. For the 1002 without my modification this means you set the potentiometer on the back that usually came with CV in to track 1V per octave but then had to add an offset of something around 2 volts to reach the lowest C. My approach disconnects the keyboard instead of adding some external voltage somewhere and simulates exactly what the keyboard delivers starting at 0 volts for the lowest C. The connection is being made by a relay actuated by the contacts in the CV jack. By simulating the keyboard, all panel functions remain active on the external CV (glide, tune, modulation) Trigger/Gate is a voltage input (V-Trig) working from 5V up. The filter input only modulates the filter setting and is not intended to make the filter track, for this purpose you should rather use the panel knob that attaches the cutoff control to the keyboard CV.' No second chance listing on this."

"Original ARP Odyssey MKIII (2821) duophonic synthesiser, with full custom metal flight-case, and Kenton installed MIDI retrofit. Orange-on-black colour scheme. The Mk III features the four-pole '4075' filter, unbalanced XLR output, and PPC buttons. Some of the sliders are a little scratchy, but will use dry film lubricant to clean those up. Amazing cosmetic condition for age - faceplate easily a 9/10, no serious no dinks or chipped keys. That said, the leather sides are scratched in places, as you might expect for her age, but look more prevalent in the pics than with own eyes. Requires C13 female power plug. Collection from NW London near bottom of M1. Free delivery by car within M25. Delivery further afield might be possible by arrangement inc. fuel cost. I will be away until April 20th but everything will be ready to despatch on my return."

"I have this beautiful Vermona ER 9 drum machine for sale. It's in perfect collector's conditions. Case, guarantee, users manual, cable 5 din to jack included.
Pure analog sound. Everything works. One thing is the cowbell sound makes constant high pitch noise. It's quite common in these machines and easily fixable.
All sounds have individual volume control (like a KR-55 or Elka Drummer One), but rhythms can be combined by pressing multiple buttons, and (unlike for example the 60s/70s Roland beat boxes) when you press in one button the others do not pop out – so you can gradually layer up rhythms or remove them one by one from the mix."
