The "Sidewinder" show you saw at ILDA was probably not the best version to see. It was a several step process - I recorded the show to ADAT, sent it to Bill Benner, he played the ADAT into his Pangolin ADAT recorder, and then synced it back up to the soundtrack. I was pleased at how well the Pangolin recording worked!
The beams were set to "all white" color because we did this recording for the Orlando LDI 07 ILDA showroom, and the beam lasers were going to be green, I just wanted to make sure all the information was there. Actually the beams have a lot of colors going on.
To see the "real thing" the MIDI sequencer drives the whole system live - MIDI into Lasergraph DSP; DSP output split between scanners and speakers. I always work in two laser channels and mix the audio.
Working process - I turn the laser off, and trigger the laser events/sounds with a MIDI sequencer, work with the images, point counts, sizing, etc. in order to "tune" the sounds and get rhythms going. At this point I am just trying to make music. At any time I can turn on the laser and see a perfectly synced light show with music! It's great fun .... I've done a lot of tunes like this.
Now I am getting into more slow stuff, the faster stuff is starting to all sound the same to me. Gotta go deeper...
Here's a video of my playing the accordion with the scanner music (also triggering a sampler with percussion sounds):
