It turns out I am not interested in performing with software, although I heartily appreciate any and all suggestions at this point. I wasn't totally clear in my initial email, but although I do indeed have some degree of familiarity with computer music, my passion is for hardware.
From what I know about myself, and I pretty much get paralyzed when I have too many options. My best work has always come from the most limited structures.
Simon's suggestion of the EH 2880 gave me pause, though. I am going to have a go at the manual, which I just printed out. I dismissed it a long time ago because I had the RC-50 at that time and there is no BPM readout on the 2880, but as long as it can deal with being a MIDI-clock slave, that should be no problem.
I still have my fantasy, though of some sort of Kaoss Pad MMDCCCLXXX, designed for looping, with a poly-touch screen and a this and a that...
