Korg ER-1 MKII "Patch from Scratch" Practice #1

I decided to practice "patching from scratch". That is I start with none of the synth drums made, build them as I go, and make a beat. Maybe if I practice enough, I can do a full on improv set with just the ER-1. I think it's plenty capable. Pardon the syncing. I'm not great at video stuff and I still need that Roland Go mixer to combine my line audio with the iPhone camera.
