Chapter 13: CoreMIDI and Apple DLS Synth
254
Specific details of your Audio MIDI Setup screen will differ from this example, depending on your MIDI interface
and your connected external MIDI devices. This is a relatively complicated example, with an eight port MIDI
interface and four different synthesizers.
If your MIDI Interface has been properly installed, the picture of your MIDI Interface will automatically appear in
the Audio MIDI Setup window, showing input/output “pins” for each MIDI input and output socket on your MIDI
Interface.
You need to inform Audio MIDI Setup about your external devices (keyboards, synthesizers, drum machines,
mixers, etc.). Click the [Add Device] button for each of your external devices, and then double-click each new
device to set Manufacturer, Model, number of Send/Receive MIDI channels, and other relevant information.
After your external devices have been created and configured, the last step is to “wire them up” to the picture of
your MIDI interface. For instance, in the above illustration, the KX-88 keyboard controller is connected to MIDI
input/output pair #8 on the MTPII MIDI Interface. Click on an input/output “pin” on the picture of your MIDI
Interface, and drag to an output/input “pin” of the picture of an external device.
After supplying this information, CoreMIDI will know what devices are “on the other side” of your MIDI
interface(s).
