Purchased 2 Atoms to use in live performance with MainStage a couple months ago. Everything was fine. Plugged it in, MainStage found it, worked the first minute I had it. Suddenly, one of the two controllers has two pads, one in Bank 1 and one in Bank 2 that fire at random and trigger their samples either on a loop or every few seconds. Changing banks triggers it; unplugging and replugging triggers it.
Can't figure out how to do a factory reset or get this to stop.
