Thanks for your help, everyone! I haven't had a lot of time to play with the Genos yet, but this coming week I'll really get a chance. (Rank newbie was referring to that) I have a lot of experience with MIDI files, but very little with Yamaha keyboard operating systems, other than the DX7, so I haven't figured out how things like registrations, one touch settings, styles, accompaniments and recorded songs interact with each other. It seems convoluted, so far. Some people like to play more on-the-fly, I guess, and the Genos seems well-suited to that. Once I really learn the instrument, I'm hoping to be able to play a song (less the parts I want to play live) I've recorded from start to finish, without variation and without any button presses whatsoever, having everything (voices, breaks, fills, intros, extros) change automatically at the proper times. That would let me concentrate on live playing and not on manipulating the keyboard. I'd like to be able to play live, both left hand and right hand independently, while the song track is playing back, without having the left hand interfering with or changing any accompaniment previously recorded. I've done this kind of MIDI play-along thing before, but never with a single keyboard. I currently use Cakewalk SONAR as a Computer DAW, which I'll probably be replacing soon, too, since it's been discontinued. Something else to learn, yay! Again, thanks for your help. I'll be trying your suggestions before asking any more (what I hope will be intelligent) questions!
