Ok I think i understand now what happened. It seems that the default settings in the Beatstep Pro is different from the Factory Default in MMC. By default the Beatstep Sends out midi to both MIDI & USB in Control Mode but the Default settings in MMC all knobs, buttons and pads only send out to MIDI and not usb. A bit confusing, and annoying to have to go over each knob, fader and pad and make them send to both MIDI & USB again.
