One thing that Flavi didnt mention is the slowing of the processor when under pressure.

Polophony dropout is one thing but if you have a busy accompaniament going and you are playing a program with the righthand you can't do a glissando up and down as the tempo slows dramatically and then races to catch up.

Try it Flavi - It's scary - but not when you are working otherwise your dancers will freak out.
