Bottom line for me is I CANNOT play piano on a 61.

I use my arranger for FAR more than just simple LH chords, RH solo stuff, and prefer to have straight ahead piano and let the Piano Mode derive the chords when I'm playing in solo arranger style. Sure, RH solo LH chords for solos, but comping I prefer to play piano. So, unless Yamaha come out with a 76, I can't gig with it.

I'm tempted to add an S900 to the studio rig, primarily for those guitars and SA voices, but I can't see myself gigging with one...
