ESQ-1 voice problem

Ensoniq ESQ-1 filter chips are all good, but voice two is much lower than the rest. Filter test shows all the others around 141, but voice 2 is around 61. What might be causing this problem?

I have a similar problem. F5 is showing 064 on my ESQ-1. Any help will be appreciated

Actually, mine is showing 64 also

Did you get anywhere with this issue?

Nope. Haven’t heard a peep out of anyone. they may be ignoring us!!
