Re: Ensoniq SQ-80 filter on one voice not reacting

2016-12-20 by alfco@...

I had the same problem it is the black capacitor below the voice. Unfortunately later was discovered that the capacitor from voice 3 (voice 6 was not working) was also the problem. Solution check which voice is not working and remove and measure the capacitor. If still not working check the other capacitors. On that SQ80 I already changed the other logic chips, but in the end these were not the problem.
