Updated Unity MIDI control

More information and the project code can be found on Github or BitBucket.

UPDATED: This plugin now uses keijiro’s MIDI Jack as a backend, removing the need to run the third-party software MIDI Bridge required by the previous version.

This Unity interface allows you to map MIDI inputs to keyboard buttons - play the mapped input on your instrument to trigger the corresponding key press. The interface currently supports GetKey, GetKeyDown and GetKeyUp events for all keyboard buttons. Direct button presses (i.e., using the keyboard rather than a mapped instrument) will still be detected.

Example Use

The following note mappings trigger:

• the ‘x’ key when note number 36 is played on any MIDI channel
• the ‘d’ key when note number 50 is played on MIDI channel 8
• the ‘a’ key when a control knob on channel 22 has a value between 3 (exclusive) and 75 (inclusive) on any MIDI channel
• the ‘b’ key when a control knob on channel 31 has a value between 50 (exclusive) and 100 (inclusive) on MIDI channel 3

These keypresses may be detected programmatically using the following code:

if (UnityMidiControl.Input.InputManager.GetKeyDown("x")) {
	Debug.Log("'x' down");
}
if (UnityMidiControl.Input.InputManager.GetKeyDown("d")) {
	Debug.Log("'d' down");
}
if (UnityMidiControl.Input.InputManager.GetKeyDown("a")) {
	Debug.Log("'a' down");
}
if (UnityMidiControl.Input.InputManager.GetKeyDown("b")) {
	Debug.Log("'b' down");
}

Using key codes rather than string arguments will also work:

if (UnityMidiControl.Input.InputManager.GetKeyUp(KeyCode.X)) {
	Debug.Log("'x' up");
}
if (UnityMidiControl.Input.InputManager.GetKeyUp(KeyCode.D)) {
	Debug.Log("'d' up");
}
if (UnityMidiControl.Input.InputManager.GetKeyUp(KeyCode.A)) {
	Debug.Log("'a' up");
}
if (UnityMidiControl.Input.InputManager.GetKeyDown(Keycode.B)) {
	Debug.Log("'b' down");
}
