I agree with Al (kbrkr). Micco's anger and frustration towards Yamaha here is unwarranted.

Except for Yamaha, I don't believe there's ANY keyboard manufacterer out there (except possibly Technics) who offer downloadable 'user initiated' OS updates other than via floppy diskettes. Yamaha should be commended for being ahead of the game in offering both direct 'PC to Keyboard via USB' and floppy diskette 'user initiated' OS upgrade options. - Scott
