The pitchfactor is a tremendous tool for me. I'm a huge pitch-shifting guy and the PF others lots of it plus a lot of other cool effects.
Only thing I really wish it did better was hand chords or multiple notes better. I have some presets with just an octave down or up, or sometimes both and I really wish it could have polyphonic playing a little better.
Is it possible to address this in future updates or is the PF already pushed to the limits of its polyphonic abilities via hardware and or other software limitations?
