I set it up so I have my snapshots on the bottom row and stomps on top. I set a flanger to switch on and off momentary. Last night, while playing a gig, I pressed down on it to enable it, then lifted my foot up to disable it, but when I started playing the rest of the song, I noticed it was still on. After trying to turn it off, I noticed that it was still momentary, but the on/off was reversed. I played the rest of the song with my foot holding the switch down. I'm not sure if this is a bug or if I'm just hitting the wrong thing with my foot. But this happened to me twice now.
