This is a minimal implementation of MIDI receiver plug-in for Unity. It can only handle incoming messages from MIDI devices which is connected to the host computer.
- Mac OS X 10.6 or later
- Unity 4 Pro
- Universal binary (runs on both x86 and x64)
The Windows version is [here] (https://github.com/keijiro/unity-midi-receiver-windows).
- In Update function, call UnityMIDIReceiver_DequeueIncomingData until it returns zero.
- Extract MIDI messages from incoming data, and use it for something interesting.
For the detailed usage, see [a sample program] (https://github.com/keijiro/unity-midi-receiver-test).
Counts the number of endpoints (MIDI sources).
Returns the ID of the endpoint at a given index.
Retrieves the display name of the endpoint. It returns a reference pointer to the name as a IntPtr value, and you can use Marshal.PtrToStringAnsi to convert it into C# string.
Removes and return the oldest incoming message on the message queue. Message data is encoded in 64-bit integer value.
Incoming data is encoded in 64-bit integer value. You can extract the information about the source endpoint and a MIDI message.
| 63 - 56 | 55 - 48 | 47 - 40 | 39 - 32 | 31 - 0 |
|---|---|---|---|---|
| (zero) | MIDI data (2) | MIDI data (1) | MIDI status | Endpoint ID |
