WIDI AU is compatible with many application supporting Audio Units.
To use WIDI AU, you need to set up an Audio Track. Audio Unit technology does not support direct MIDI output to the host, and you have to use either virtual or hardware MIDI loopback to output MIDI from WIDI AU to the host's MIDI Track. Connect Audio To MIDI AU to get data from the Audio Track and send MIDI data to a loopback or an output device.
Generic procedure for setting up WIDI Audio To MIDI Audio Unit
1. Open the AU Host application and load Audio data into it.
2. Add WIDI AU to the output of an Audio Track or Audio Player. It may require first adding the WIDI AU to the workspace and then connecting its input to the Audio Track output.
3. In the WIDI AU window choose the option page, turn on midi to midi out option and select IAC Driver Bus as output.
4. Create a MIDI track if possible. Attach WIDI AU IAC Driver Bus output to the input of the track.
5. If no tracks can be created, try to attach IAC Driver Bus output to any MIDI output device.
7. You may also need to tune Recognition Parameters to achieve the best results.
You can also record MIDI events to a MIDI file with a built-in MIDI recorder. See routing MIDI for details.
For more detailed info please refer to the documentation for your particular host .
Note: In this instruction it is supposed that Apple IAC Driver is activated on your system. If it is not true, refer to routing MIDI on how to activate it.
