First, I have to remind myself to ABC: Always Bring a Camera. I missed several photo opportunities before and during our rehearsal in San Francisco on Wednesday. There were some great shots on the new Central Freeway terminal ramp. And then the “kitty moments” during the rehearsal with Polly Moller and John Moreira. I did snap this cell-phone pic of John Moreira's cat Crescenda rolling around among our cue sheets and amps. She and her fellow cat Pearl joined us several times during the rehearsal, but Crescenda's little act stole the show.

Musically, I had a minimal setup – a subset of what brought to the Skonkathon two weeks ago – just the MacBook, the E-MU 0202 | USB and a MIDI keyboard. The Mac was running the new script-based Open Sound World to process live guitar input. The processing worked quite well, I think, with several wavetables, ring modulation, and a rather nasty little FM algorithm (it's a lot like those distortion-modulation “sound mangler” pedals). Both the guitar and processing needed to fit within pieces with voice, flute and existing electronic material.

UPDATE: You can read Polly's account of the rehearsal and Crescenda here.

The one concern was the frequent OSW crashes – it wasn't a huge problem during the rehearsal because the system can reset itself very quickly (far more quickly than the older UI-centric version), with only a few seconds of dead time. But still, that's not cool. I suspected something related to the MIDI input handling. Fortunately, last night I was able to track down the crashes last night. They were indeed in the MIDI handling, some issues exposed by the multi-processing with the Core2 Duo. Easily found and fixed by playing the patch with a lot of MIDI control, with the laptop and keyboard on the coffee table. Actually, I made some interesting lo-fi music with the built-in mic and speaker and feedback while testing and debugging. This will probably form the basis of my next piece.
