For me, it is so invaluable to have the left voice frozen, say on strings, and to be able to change the right voices via OTS.

I am having a great time with the PSR2000. I'm getting a lot of jobs with it, so I'm very very pleased.

I am frustrated about the lack of flash rom because I was hoping that Yamaha would introduce new features with successive updates - not just fix bugs.

I definitely will not update. The ability to freeze just the left voice is too valuable.

Good luck to those who update.
