First of all, thanks everyone for the helpful post.
Fran - I will check tomorrow to see if I can find out how to switch on the output midi channel on the Tyros. Since channel five transmits to the internal harmonizer I thought it would be transmitting to the outpout midi too but apparently not.

Mike - I glanced at the manual but I didn't see any info on it. Probably just overlooked. I'll try again.

Donny - I always seem to have distortion when I run with the internal harmonizer. I've tried all of the suggestions that I have read on the forum but to no avail. I finally broke down and purchased a TC Helicon awhile ago and I'm trying to get it up and running.
Just curious are you going back to the Tyros 2? I'm pretty happy with mine, but I can certainly understand your desire to try and keep getting better and more efficient system(s). Good luck with whatever way you go.
