OK - Three replies:

AJ - It seems, in a round-a-bout way - you are telling me the polyphony DOES shut off the harmonizer, right? That's the way I see it. I think it's a bad way to allocate tasks.

DanO - The harmonizer on the PA80 is also unacceptable to me because it's always in vocoder mode. That means it ONLY plays the notes I Hold doen with my hand. 1 note = 1 harmony, etc. I want CHORD recognition. I dopn't know about the instant on or not, because i won't use it.

Frankie - Nope - You MUST use the huge multi pedal for the on/off of the harmonizer. There is NO assignable jack. I found that to be a cheezy omission too.
