Cass, I assume you mean performing rig (as opposed to studio). I currently use just the Nord C1 but plan to add the Roland Sonic Cell as extra voices once it starts shipping. In the studio I have scaled back to Tyros 2 and PA1x Pro for fun and as compositional sketchpads, plus Motif ES, Triton, Roland VP550, and a Roland A70 w/expansion board controlling a bunch of softsynths (which I rarely use) for serious recording.
I'm picking up a digital piano (Behringer EuroGrand) for the rec room but that's just for fun and for the grandkids to bang on (at least that's what I told my wife). It has pretty stiff action and should hopefully help me regain some finger strength and stave off arthritis (plus, they're really cheap
). It also has a two-track sequencer, good for quick-and-dirty solo piano recordings.
I've got a bunch of other keyboards and modules back in the storage room but they'll likely stay there 'till I die and my wife tosses them into a dumpster (and possibly me along with them). There's an acoustic piano in the living room but my wife is the only one that plays it. Uh, have I gone WAY past answering your question, yet?
