MDCommander (MegaDrum Commander) is an app to control a MegaDrum module over USB, MIDI or wireless MIDI.
MegaDrum is a Trigger-to-MIDI module/controller which can be used with many varieties of Edrum kits/pads/cymbals and outputs MIDI signals which can be fed to a computer with drum sampling software,e.g. Garageband, BFD, Toontrack, Addictive Drums, or to a MIDI aware sampling app on an iPad.
