Additional SYNTH CITY Listings
"This workhorse of a synth has been with us from the 80's and well beyond! From Michael Jackson to Gary Numan this iconic synth has been on countless records and sounded excellent throughout all of them. This particular D-50 has a couple screws missing on the bottom cover, but aside from that is in very good condition. The cmos battery has been replaced, and the original back light is still working great!"
Note the SIR (Studio Instrument Rentals) label on bottom.

Vermona DRM / Digital Rhythm Machine

"Programmable analog drum machine from East Germany, often tagged as the "east block TR-808". I think it deserves better than this comparision, since it's a very nice sounding drum machine on its own, with many features for the time (MIDI IN and OUT - sync and trigger, stereo output, optional trigger inputs and individual outputs etc)
Unit was serviced, calibrated and is in fully working order. It has the latest firmware which fix the MIDI timing issue earlier units had.
If you don't know these units check the demo I made with another unit [in the listing and previously posted here], I serviced several of those units through the years.
Cosmetic is in excellent condition with only very little wear and scuff."

"This is a short video of my 1984 Rhodes Chroma. I am the original owner.
This shows me creating a scratch patch using the CC+ Split 39 function , which shows the instrument functioning as it should"
via this Reverb listing
"It is registered on the Chroma Website 0660
Is it fully functional , has the CC+ and midi interface , and a new power supply installed by the best Chroma tech on the east coast.
It is cosmetically beautiful. The black metal top shows a few scratches from having a Rhodes Chroma Polaris on it years ago, hence the 'excellent' vs ' mint ' condition
It has a new flight case to original specs, all original manuals , all needed pedals , although those are not original"
