PB single note in a chord?

[trogluddite]

I agree with tulamide's assessment. The MIDI gadgets that I've tinkered with could probably be adapted quite easily to identify which note(s) should respond, but getting that info out to the correct poly voices might be more tricky. Packing flags into an array/mem with an index for each note number is the only idea that immediately springs to mind.

Having read around a little bit, I rather like the sound of another of the DX-series PB options - PB for notes held on the keyboard, but not for notes held by the sustain pedal. I can't quite imagine how the hi-note and lo-note versions would work when there are spaces in the "soloing" which would make the priority note change to another one (unless it's a keyboard split kind of affair).
