So I am messing around with settings, and every time I press Function, then Pad Action I can mess with sound/effect settings. If I press any of the lit right-side outside buttons (I have no idea what they do yet, but they seem to limit the length of the note to 32/16/8th etc), there is a good chance that the machine will just flick off and on again, thus losing any unsaved work. Am I messing with things I shouldnt be, or is machine malfunctioning?
