Feature Request: Polyphony in Unity Mixer

[FunkybotsEvilTwin]

Summary:
Would like to see Unity Mixer support polyphony.

Use Case:
Was just patching together a MW+Vibrato and Pitchwheel setup where Unity Mixer was the last thing in the chain, merging the various V/OCT signals. Worked great on monophonic signals, but had to go hunting for a polyphonic Unity mixer (landed on Vult's Knobs in Mix mode) for this particular setup to work with polyphony.

Would be great if Unity Mixer supported polyphony in the future.
