Jerry,

I look at this a bit differently. The Barbetta is an outstanding amp and it has lots of great features. The CM-30 is an overpriced guitar amp that IMO really doesn't cut it. I suspect that you can get all you really need out of the Barbetta by merely tuning the keyboard's Global EQs, and setting the EQs on the Barbetta. One less piece of gear to haul around, less things to cause problems, less setup time. If I were in your shoes this is the way I would go. Fortunately, I'm not in your shoes. The decission is yours.

Gary
