As you said Tom the recordings are stored on 'Floppy' or you can store them to the User Memory Area. They've doubled the User Memory on the PSR 2100 compared to the PSR 2000 which is now (discontinued). So you have roughly the size of "1" floppy disk to store your songs on the User drive, approx. 1500kb. Floppy storage is unlimited of course as long as you keep shelling out for Floppies and don't mind loading them back into the Keyboard when you want to pull up a song.

I think the PSR 2100 has improved the Song 'loop' function but I'm not positive. The Tyros as a more sophisticated song playback 'loop' "repeat" function on it, (if I'm understanding you correctly when you say "loop sections".

Best regards,
