Note: MidiJack is superseded by a new MIDI plugin Minis. Although you can still use MidiJack with the latest Unity version, it’s recommended to migrate to Minis for further updates.
MIDI Jack is a MIDI input plugin for Unity.
- Unity 5
- Windows or Mac OS X
Download and import MidiJack.unitypackage into your project. That’s it!
See the troubleshooting topics if you encounter any problems.
The basic functions of MIDI Jack are provided in the MidiMaster class.
The channel arguments in the following functions can be omitted. In that case, the functions return the values in the All-Channel slot, which stores mixed status of all active channels.
MidiMaster.GetKey (channel, noteNumber)
Returns the velocity value while the key is pressed, or zero while the key is released. The value ranges from 0.0 (note-off) to 1.0 (maximum velocity).
MidiMaster.GetKeyDown (channel, noteNumber)
Returns true during the frame the user starts pressing down the key.
MidiMaster.GetKeyUp (channel, noteNumber)
Returns true during the frame the user releases the key.
MidiMaster.GetKnob (channel, knobNumber, defaultValue)
Returns the controller value (CC). The value ranges from 0.0 to 1.0.
Returns the list of active controllers.
There are also delegates for the each type of MIDI event.
- MidiMaster.noteOnDelegate (channel, noteNumber, velocity)
- MidiMaster.noteOffDelegate (channel, noteNumber)
- MidiMaster.knobDelegate (channel, knobNumber, konbValue)
MIDI Monitor Window
MIDI Jack provides the MIDI Monitor window, which shows the list of active devices and incoming MIDI messages.
The MIDI Monitor window is available from the menu
- Currently MIDI Jack only supports Windows and OS X. No iOS support yet.
- Only supports note and CC messages. No support for program changes nor SysEx.
- The MIDI Jack plugin always tries to capture all available MIDI devices. On Windows this behavior may conflict with other MIDI applications.
