This is great feedback. Sounds like my only remaining concern is how I can get a keyboard / controller in the mix. Their site says:

" Used in conjunction with a Computer, Master keyboard, Midi accordion or Midiguitar..." The key word there is "OR". I can see how it will work with BB as the sequencer. But what if I want to use a keyboard to "input" MIDI data to a RB track? Like maybe add a track with some percussion or some synth hits.

Looking at the user manual http://www.ketron.com/specs_descrit.asp?mod=SD2&action=download doesn't quite answer my concern. I think the keyboard MIDI out would have to go into the Ketron MIDI thru, but not sure. I am working from a laptop and would have to use one of those MIDI-USB thingies.

The other (more expensive) choice is the Roland Sonic Cell. That seems to solve a lot of issues but it's about 2X the $.

Thanks for the help so far. This is very encouraging...
