Processing the original signal into something synth-like is attractive to me.I don't believe that uses polyphonic pitch detection. I believe those products use waveform morphing.
No delay or tracking issues, inherently polyphonic, and most importantly, keeps your touch inflections, where an actual synth needs some other back-channel controller setup to allow even that "artificial" one-dimensional level of difference between notes.
