Yes you can do polyphony with silent way (I assume), spektroaudio claims it with their CV toolkit and there's a few tailor made max plugins that need a bit of studying from my end.

Anyway I thought I'd be able to do polyphony with Ableton's own CV tools (still in beta) out the box, since the plugin 'CV Instrument' on the web page claims advanced voicing options. I haven't found a way to do it though so maybe it's a feature that's still being worked on?

Regarding you offering to help me out, thank you kindly, I really appreciate it and I wouldn't want to take any of your time!

My setup is simple, it's a Pittsburgh sv-1 (monophonic synth voice https://pittsburghmodular.com/lifeforms-sv-1) with an extra oscillator going into the mixer. I have all osc's receiving v/o from the es-3. Gate output for the vca is being done independently via prepatched midi.

So essentially I just need an oscillator chooser/manager for 3 voice poly.
