To support Leap controller is not quick task because Leap Motion do not offer SDK for compiler we use for BEYOND. It means that we will need to write/reconstruct SDK by ourself what.. possible but not quick or easy process.
Second detail - IR noise that can cause a "noise" in data that comes from controller.
In any case, you can play yourself with various Leap to OSC, or Leap to MIDI applications and see how much you like it.
