Hi there,
I have a Crumar Orchestrator that I’m trying to repair. It is all working well after replacing some sliders except that the keys are triggering multiple voices on some keys. So you press one key and get a dissonant cluster of notes. I’m thinking it’s either a power issue or an issue with the frequency divider IC’s. Thought they all look like they may have been replaced in the past. Does anyone have advice on what I should be testing?
The schematic is not the best and I’m not even seeing the board P-392 with the TOS and frequency divider ICs on it…
