Seriously, this musicthing site is amazing. Worth a sniff around.

Three treadles...cool. I envision a three pedal controller/multi effects unit in my future...I can't count the times I've thought...if I had that parameter controllable with my foot life with electric guitar would be enhanced.

Blend mixer control

Amazing, creativity!
