“Sequential Circuits Prophet 600 For Parts or Repair Rare Japanese Memory Mod.
Includes synthesizer, hard case with aluminum trim, original Japanese documentation on modification.
This came from japan, not sure what work this needs, if any. Untested. It has been modified with some custom Japanese circuit dated 1987. I think the circuit added a hundred or 2 memory slots for voice recall during live performance. (Like ymo) That’s all I can really say.
I think this is the mod
“Ver.6E3.1にアップグレードすることで、プリセット・メモリーが2倍になりMIDIチャンネルの指定ができるようになります。
また、音源にノイズが追加されます。
費用は26,250円です。ご購入と同時なら改造費は10%OFFです。
or
pre-set it by upgrading it with Ver.6E3.1, and memory doubles and comes to be able to appoint the MIDI channel.
In addition, a noise is added to a sound source.
The expense is 26,250 yen. The remodeling costs are 10%OFF if simultaneous with the purchase.”
So the mod cost 26k yen at some time it seems.
It is in beautiful condition cosmetically.” Click here to visit listing on eBay
