MIDI BLadE is a midi controller concept that was derived from the electronic sport of fencing, at once a musical instrument and a playful dueling game that resembles traditional sword fighting. This device draws a powerful interaction for solo play or two+ users to intuitively find fluent musical expression with no training whatsoever and can be leveraged toward meaningful musical composition and choreography. Players require neither musical background nor swordplay experience to enjoy finding harmony through battle with the MIDI Blade.
