No sampler. And one where the sustain pedal doesn't work hardly qualifies, either...

Main point Donny is just the willingness to TALK about bugs. I have never shirked reporting issues with my G70. Heck, I even RUN the Bug Forum at R-A.com, and have always made my issues with the G70 common knowledge around here. I see little reciprocity, though.
Just be grateful that I haven't yet succumbed to the gorgeous SA sounds and Mega guitars. Because whatever bugs and niggles DO exist on Yamaha's would no longer be the great secret so many have tried to make them! I push arrangers as hard as I can, and I push the manufacturers just as hard when they make boneheaded decisions. And I try to broadcast this knowledge in the hope this prods the manufacturer to make good. Sometimes it works, sometimes it doesn't. But your chances of it happening are less if no-one KNOWS about the bugs save a few 'experts' on a bug forum...
