I was also going to say that Korg's Pa2XPRO has micro editing capability. I think the Pa800 has that ability too. Unfortunately Yammie has dropped the ball on the Tyros line. If you want micro editing on a Yammie your only option is their totl workstation line e.g. Motif ES/XS. Maybe the Tyros4 will be different but knowing Yammie I won't hold my breath. Same goes for 76 keys.

All the best,
Mike
