I have never been a fan of internal keyboard sequencers though I know many are... I always prefer computer sequencers which give far better results. Unfortunately, the Tyros does not come with a computer sequencer program. However, it does come with voice editing and file management programs that can be used alone or as OPT panels. OPT panels are sub-programs that can be opened within compatible sequencer programs like Cakewalk Sonar 2.0, which is a very popular pro-level audio/MIDI recording program. I think this is a very sensible idea. Yamaha has OPT panels out for the Motif and I hope they will come out with an OPT-based XG voice editor soon.
