So far I haven't had the need to string that many registrations together, but I certainly see the advantage and agree it is the way to go when needed. I have several medleys that require style, key and tempo changes, but so far all fit into the 8 reg. buttons. The PSR2K certainly has raised eyebrows at many of the functions I play. You can make it look so easy they don't believe you are actually playing the thing.
