Well, this is the first time I tried the harmony function on my psr3000.. Lot of clipping and I wasn't over-driving... Covered them up by over-dubbing.. Anyway, not sure I'll use this feature... If you have a moment check it out..
Tune is South of the Boarder.. http://www.soundclick.com/pro/view/01/default.cfm?bandID=313920&content=music

Of course all produced on the PSR..
Thanks
