VCO2 Offset issue on a JP 6

2013-12-05 by <bob@...>

Hi

Just wondering if anyone else has had this issue, and if so, if they have any insight into how to cure it.

With the Tune knob set in its' mid position I have quite a detune on all voices. If I move the knob into a 2 o'clock position I'm roughly in unison.

I've calibrated the synth but the issue persists.
If I measure the voltage on the pot it's as it should be ie. 2.5V at 12 o'clock,
Looking at the output of the multiplexer I can see that the level is consistent with the other controls.

Any constructive input most appreciated.


Bob
