this is a really good test here. so both the x0xheart and dixie shift up in pitch, but the dixie comes down faster? maybe the x0xheart doesnt completely come down? can you post a picture of your x0xheart (both sides)? also, with your scope tests, what was your V/div settings? if you can set your scope to DC couple, 50mV/div, and then adjust the DC offset so that its at -2V, you should be able to bet a clear view of what the slid CV out is doing. you could put one probe on each side of the 1k, and then youd see how well they track. some scopes limit the DC offset value based on the V/div setting. so if you cant get the -2V offset at 50mV/div, try 100mV/div. again, were expecting 100mV movement at the most.morbank wrote: ↑Sun Dec 20, 2020 8:42 pmIf I set the x0xheart to C2 (VCF output set to INT) and the Dixie to C2 and then apply a constant 5v to the Accent Gate input with a repeating gate from the x0xb0x to the x0xheart’s gate input (the pitch rise only happens when I send gates to the x0xheart’s gate input) the pitch of the x0xheart rises up and is never in tune with the Dixie. But it’s closest in pitch with the Dixie at the end of each gate.
its sounding like there is a bit of extra current flowing into the CV pathway when accents are active, as a result of the envelope circuit. U12 could be the culprit, as it connects to both the accent circuit and the CV input circuit. if there is extra flux in this area, or that switch has internal leakage, then that could cause a shift when accent is engaged.
