+ 1 for a polyphonic pitch shifting algorithm (or updated tracking on some existing algorithms if that was possible). The flexibility of the H9/pitchfactor algorithms with multiple voices, delays, feedback etc is unrivalled, but a number of companies (EHX, digitech, morpheus, earthquaker devices, Zcat) seem to be getting some pretty good results with polyphonic tracking and it would be awesome if the H9 could get on board with that too!
