Hi I have a prophet 5 rev3.3. I am having a problem with oscA being out of tune with oscB
ie sound like one is detuned with the other. Its hard to tell which osc is at fault, maybe both

I have changed the osc VCA's but with no resolution of the problem.
It only affects voices 2,4 & 5

Any help appreciated
thanks
Alan

We used that keyboard alot in the early 80's, and the tuning was ALWAYS a problem. I have a friend who had a small timer on stage to turn the kb on about an hour BEFORE he got to work, because it seems to settle down as it gets warm. Did you notice the same thing? Maybe it'll work for you too.
