I just spent a little time with the PSR2100 sequencer...If you use this keyboard, get your Sonar up and running. It appears the sequencer can record 3 tracks[all 16 channels], it is designed to utilize accomp/styles to record multi channels. It is possible to go into song creator to make edits on any channel, but we can only record in 3recording tracks..I would have to agree with others , this is just a scratch pad sequencer...I am curious, is this the same on the Tyros?
