We did not actually use the Lake processor, it was there because I was purchasing it from Bennett. IIRC, it was taken out of the box the "show it off" a bit.
All processing was done in the APB console and EONA boxes, no outboard whatsoever. Bennett and I laughed quite a few times during the evening about the irony of the demo being about losing all of the analog in your signal chain when recording, yet we were playing their electronica through pure analog end to end.
Overall a good day, and yes, it was also fun to blow away the preconceived notions of the average GC customer as to what a rackmount mixer and tiny little powered speakers could do.
