Circuit Overview:
Another 'synth on a chip' based synth but with 8 voices that can be allocated or stacked to 2 or 4/voice. No velocity however.
Service Tips:
Many similarities in construction to Multi-Trak. While keys have the same design the keyboards have a different interconnect. The one I got has some tears in the panel membrane switches. I've developed a technique for repairing these. Use a contact adhesive that stays flexible and douse some THIN slices of polyfoam or like that with it too and lay it over at the appropriate moment of dryness. You can strategically build and mend breaks and tears in that stuff.
By this time manufacturing was pretty good and power draw low so you probably won't see many power supply problems or chips dying aside from the CEM3394 possibly being the most congested analog component. But I'm yet to see one fail in the synths I've done. By the way this synth DOES NOT share the lovely 'bug' in the Multi-Trak where you have to load patches when the battery dies before it will even allow you to program patches and get a real sound out.
Parts:
I have lots of parts for these synths save the CEM3394's unless I scrap out a multi...
