Don't see any MIDI inputs so at the moment the Pressure Points is your only controller. You might want to add a Brains to automate it. For half the price (new) of a Braids, you could get a Synth Tech E330 multi-timbral VCO. Or you could go with a much cheaper bread and butter analog VCO, like a TipTop z3000 or a Intellijel Dixie. Research the Rosie - Makenoise makes great stuff in general, but IIRC not everybody is happy about it. Sure would be nice to have some kind of LFO
Overall, seems a good rack for a start - once you start making music it should be obvious what you need next.
