Ok, no feedback so far but at least I have a personal update on this fantastic voyage: I'm still struggling but have now achieved at least two simultaneous OSC sounds via these connections:
Mthr32 KB Out to Wrksttt VCO Exp FM In
Wrksttt VCO Out to Mthr32 Ext. Audio In
I am not using the Wrksttt's audio out at all.
FWIW, I tried M32 Gate Out to Wrksttt Gate Out (supposedly also an In?), but got nothing.
Both OSC's now sound and the independent knobsets of each device function on each oscillator (which I want), but they don't stay at a set interval as I move up/down the Mthr32 keyboard. Aka, if I tune them together, then raise or lower the pitch using the M32's keyboard (reminder, goal is for the M32 sequencer to run both, as if the M32 already had another OSC) they don't stay in tune when I change the pitch up or down. One drifts (I assume it's the Wrksttt) from the other, and the OSC pitch intervals widen (or narrow) as you play the Mthr.
Am I making sense? Is this thing on? Bueller?
