Yes, a breakdown of how you brought each element in and out, whether you used factory Registrations, or custom ones, factory Multipads or custom ones etc., would help enormously in understanding how you pulled this off.

It reminds me a lot about how you can use the K2500's Performances to do quite elaborate things orchestrally with a combination of pedals, and switches in realtime. I'd VERY much like to understand how this was done...
