Note these are from supporting member, Loscha.

The are listed for parts. Note the smokey transparent music stands, that also act as front panel covers when not in use, on each of them.

"Of Note: all of these keyboards have the smoke grey plastic music stands, and they don't have the tabs broken off!!!!! These are quite rare in any condition as they fall off if you carry the keyboard at an awkward angle, and can shatter.

Despite my vague notes here about the keyboards partial functionality, the only one I can be sure of is that the KB-700 actually was making good noise, accompaniment played, voices switched, etc.

Updated to add: the winner of the auction will receive the KB-500 service manual via email. I had to purchase this separately.

NO RETURNS ACCEPTED -- THESE ARE SOLD AS IS, AS STANDING.
JVC KB-500 White Keys - no sound, doesn't power up
JVC KB-500 Black Case Silver Keys - no sound, doesn't power up
JVC KB-700 - this one works except for tempo slider.
Lowrey Micro Genie V-120 "Mach Plus" (rebadged JVC KB-700) only a few keys worked a few times, I think the drums worked however

JVC KB-700 features and demo

Published on Nov 18, 2017 Daniel Arena

"JVC KB700 (also sold as Lowrey Micro Genie V120).

Super weird mid 80's organ:
Solo section (square-wave + discrete VCF)
Poly section (divide-down? but phasey? there's a bunch of mysterious ASICs in there so it could be anything + Paraphonic VCF, subtle stereo spread + ensemble effects)
Analog + discrete drum machine
Bass synth
Bunch of other weird crap.

Sketchy weird beastie of a thing. Does some cool stuff though.

Obvious low-stress (and probably reversible) mods available for drum triggers and some VCF params. Medium-stress mods likely for loads of other stuff.

Some reverb added, no other effects. Apologies for the gross playing, I'm not really a keyboard player."

There was only one other post featuring the KB-700 here.

Vintage Analog Synthesizer RMIF Opus: Sound Demo

Published on Feb 28, 2017 Najvrtson

Here's something most have likely never seen before, a vintage soviet RMIF Opus. I believe this is the first one to be featured here.

"The tune (russian folk song Polyushka Polye - despite the fact, that the instrument was made in Riga, Latvia) was entirely recorded on RMIF Opus, except of drums (JVC KB-700) and some reverb and delay effects. Opus was made cca in 1988, but technically wise it was obsolete at the time. It is based on divide-down technology, but has very nice filter (LPF, BPF and HPF with resonance), excellent chorus unit, ring modulator and some other fine features. Enjoy its sound!"
