Leeboy, in my posts I have made that quite clear (and I think Russ may think the same as we have the same view) that for someone using the Tyros at home (the Yamaha MAIN market - home users) this would be a wonderful and fun device for those who cannot sing or who sing poorly. It would encourage more active participation in adding vocals to their playing.

I re-state that for someone professing to be a pro singer/player finding they HAD to use it, they should retire.
