My minibrute, upon start up will make no sound. The octave light blinks green and pulsates and that is the only sign of "life" in the thing. It started doing this behavior about a month ago periodically, in which case I would power off and on a few times until it worked. I would even hold down the octave switches while powering on, and that would work sometimes, but now its to he point that it never works, and the Minibrute is 100% non functional. I tried to update and the the updater said please connect minibrute. Everything was connected. Please help!
