I, and my previous audiences, absolutely love the sound and quality of the audio styles that Yamaha has introduced in its more recent PSR series of arranger keyboards. The only unfortunate thing I discovered is that you cannot record the audio styles (which use live drums) using the onboard USB recorder. The reason being I believe is because the onboard recorder/player is utilized for the audio style playback and both recording and playback cannot not be done simultaneously using the same device, which makes perfectly good sense. As for the editing, well, I'll leave that to Yamaha, whom seems to do an outstanding job in this respect.
