Diki, that's why they have a hold feature on the left hand so the player can lift his or her hand and use the pitch bend, push buttons, etc... Guys like Don Mason are a treat to watch perform, mainly because his left hand only touches the left hand chord for a fraction of a second, then it quickly goes to the pitch bend device for his guitar emulations, which are absolutely incredible.

Gary,
I'm sure you get Diki's point about how a lot of bends seem to occur at chord changes. It's not that big a deal, as evidenced by DonM's guitar emulations, but it's an issue for some.
With me, I've been dealing with that for years, and it's never a bother. I just do the best I can with the hand I've been dealt. The Tyros4 doesn't have a chord sequencer, which would make it easier, but I wouldn't buy another brand just for that feature, and give up the sounds I love on my Yamaha.
I'm not that much of a perfectionist...I just want the listener to be at least able to identify the instrument I'm emulating at the time. That's good enough for me.
