Hi Keith,

I can tell you what I've already learned from other members of the 
group, and that should answer most of your questions:

> Pro models:            Much greater sensitivity is added to sensors

That answers your questions about the differences between models.  As 
far as the file format is concerned, I believe they all read the same 
format, and you can convert conventional midi files to this format if 
you want.  Correct me if I'm wrong here guys.  As far as the other 
brands out there, I'm told that they aren't nearly as accurate at 
recording and their playback isn't as sensitive as the Yamahas.

Hope this helps.
