UMC1820 : Useful pedal for live MIDI control if your hands are too busy.

Used this pedal to control various functions like patch/song changes, backing tracks, loopers, channel mutes, and software guitar effect plugins within Apple Mainstage for a gutarist/singer live setup. Lots of pedals and banks. Painful to program manually (like a manic game of Simon Says), but there are a couple of 3rd party software programs that make the mapping more visible and easier to perform. I started simple and then added more controls. I didn't use anywhere near the 100 or so channels available. Physically the unit is quite well built and heavy so it stays where its put on stage. I'm only an occasional performer and I've only had it for a few months so can't vouch for its robustness under heavy use/gigging etc. One feature that slightly annoyed me was the LED on each pedal illuminates when the pedal is pressed but doesn't extinguish if you press again, only when you press another pedal, so if you use it for something on-off it doesn't reflect this.
