Two keyboards at a gig is no more preposterous than a different ONE every month or so

I have always said that if the damn manufacturers would pull their heads out of their arses, and make it so two different arrangers could communicate easily over MIDI (start/stop, variation and fill changes, Intro/Endings and breaks at the VERY least) I would already be gigging with two... probably my G70 and an S900 (for the guitar strums, etc.).

Mind you, if you don't really play them a whole lot, I guess one makes more sense...
