We made an audio effects controller for DJs using the Myo armband. Moving their arm instead of twisting a knob helps DJs multitask, be more performative, and have fun without sacrificing precise control--aspects of the experience which were important to our users. Through several iterations, we tested using Leap Motion or Myo for the best possible user experience.
Using C++, the application converts Myo input to MIDI output. The MIDI output goes to the GUI, written in Processing, and to whatever audio software the DJ prefers, such as Serato or Traktor.
