Soundless joyMIDI

I made a portable MIDI controller, there are 4 operating modes in it, Keyboard(MIDI), DrumPad(MIDI), DJ(MIDI) and GamePad(HID-joystick).
The DJ mode is for Mixxx. I have done the mapping files and test it. Currently my job is add this mapping to Mixxx repo to native support it.

If there is any suggestions, plz let me know.
