"Lovely Roland VP-550 in excellent working condition, you can hear it in almost any live performance by Air, one of my favourite band ever. The aesthetic condition are good for its age with minor signs of use, the only bad thing that I want to point out are the 3 tape signs on the upper right panel, I don't know if they can be removed with a specific product but I don't think so, it looks like the grain of the plastic was damaged. After several bad experiences with customs, I will only ship to EU, UK and Switzerland."

"Roland JX-3P Chromatic + Midi upgrade + DT-200 programmer package
Very special, fun & ultra rare version of the JX-3P. This will get you different results then jamming on an ordinary piano keyboard. Conversation piece & creativity bomb! Can be played over midi too so it does all.
Very good condition. Note the nice wooden sides.
- The midi was upgraded with the kit from Series Circuits (Australia). Now you can use the Programmer AND external midi at the same time. On stock unmodified JX-3P you have to choose between the 2 so you can't have it play a midi sequence and turn the progger knobs at the same time (it was the first Roland device with midi..). This kit works flawless and nice.
- The DT-200 Programmer is new in the box. This really opens up the JX-3P and you can tweak all parameters!
- Original JX-3P manual included (French / German)"

"Godwin string concert fully overhauled by James Walker in 2024, including a full recap of all the board and power supply. A fully polyphonic Italian string machine that sounds superb! Near good condition with slight rust spots on the front panel, otherwise a particularly good example, comes with lid, pick up from South Sheffield or Crich, unless VEMIA can collect and deliver."

Roland SH-7 44-Key Duophonic Synthesizer

"Newly serviced and perfectly working SH-7! A rare synth from the SH-series. All working perfectly and sounding great. All knobs intact and even including the original hardcover. It’s duophonic which is a cool feature, compared to a mono synth.
Ideally pickup, I’m in LA area.
About the SH-7
A very flexible oldie from Roland. Standard SH sound with lots more creative control and tweak-ability! The VCO's are a little different than traditional SH synths, they are syncable! There's also a mixer for all the audio signals which can be distorted for brash techno sounds. It's fun and easy to use but very powerful and perfect for screamin' techno sounds and effects! It features many new functions like an external audio input, a ring modulator, syncable VCO's, more waveform shapes, white/pink noise generators and sample+hold."

Moog Polymoog 203a FULLY FUNCTIONAL with Polypedal 285a and full leg assembly

"Fully operational! Rare and probably the most unique synth ever made. Nothing sounds like a Polymoog. This is the full version, not the slimmed down preset version. It’s not calibrated but all that means is the presets don’t sound right. It still functions and makes awesome sounds like classic Gary Numan. Small chip on corner and a couple keys are not even. This is a classic hammer action keyboard and the keys can be adjusted. I have had one D key stop working but it was just a dirty contact and it’s working fine now. All poly cards work great. This was serviced before I bought it last year but it doesn’t like being shipped so that’s why the presets are a little off. I never liked the presets anyway and you can adjust any preset anyway you want. Poly pedals work great. You can do a lot with these. I use it to control modulation amount and filter cutoff plus trigger mode. I have a few videos on YouTube. No shipping and no returns. It’s a working Polymoog but they don’t like being moved around. Includes all original legs and leg parts. Little demo here but there’s a couple more videos from the same channel. This is the actual Polymoog fo sale. Willing to deliver to Madison area."

"Rare Soviet-era analog drum synthesizer Marsh (Марш) UDS from 80-90's, manufactured in USSR. This listing includes the main analog drum module (requiring repair) and a complete set of 6 working drum pads.
The Pads - Fully Working
The real treasure of this listing is the complete set of 6 FUNCTIONING original Soviet pentagon-shaped drum pads in very good condition. These pads are highly sought after and difficult to find as a complete set. All 6 pads are responsive and in proper working order.
The Module - For Repair/Parts
The main Marsh UDS analog module powers on (produces hum through Line out) and detects pad strikes, but does not produce sounds. The unit responds when striking the pads but no audio output is generated. The module requires professional diagnosis and repair."

"A-V-P Synth RITMOBOX had a broken power supply. AC! So I had no substitute and could finally fix it now. Happy to welcome the pure sound in the studio again!"
