Circuit Overview:
A divide down oscillator synth with VLSI chips that allow it to actually have simple envelope controls for each note independently. 3 oscillators that can be tuned independently for the sections.
Service Tips:
I've seen op amps fail and send DC voltage into a mix that totally offset the brass voltage giving it an early distortion. Other issues? Email me!
Parts:
If you need anything ask. I have a scrap units. Only a few knobs left.. the one biggest one is gone.
Very difficult to find parts for these things. See Sigma page for easy fix on joystick knobs.Contact
