Sean:
Yes, I used the PSR2000 exclusively and the help (for editing and vocals) of Cakewalk Pro9, great program with lots of features and a great interface. It works "flawlessly" with a PC with a big HD and a fast CPU. You also need an audio USB interface like the Edirol UA-1A ($89)to get your audio(vocals, etc.) "digitalized" into the PC.
Let me know if you need more info, I'll be glad to help you.
reagrds,
Mario
