My main wish for the H9 would be polyphonic pitch detection for the pitch shifter so you could play chords. This is what EHX is doing in their latest pedals. Thinking about buying an EHX Pitchfork for this. But it would be great if this could also be done with the H9. It would open up many possibilities for other algos as well. I Think that polyphonic pitch detection is the future for pitch shifting.
