The 9000pro is not degigned for the SOLO pro, really. It's more of a "band" pro because of the size, and lack of speakers.
I mentioned this to Mark yesterday, and stated that the "one nighter" of todays needs a smaller, powered version that is lighter than the 9k.

The 9kpro had EVERYthing you'd need to work as a soloist ...... but the size made it just too cumbersome to deal with, and the lack of speakers just put it out opf range for the smaller jobs. The PSR9k was not a suitable substitute, because of the awkward size and same horrible weight factor.

Face - it ... these two are just too darn heavy to be called portables. I'm an artist, not a piano mover.
