External Instrument

You can use the External Instrument to route external MIDI sound generators through the Logic Pro Mixer, which you can then process with Logic Pro effects.

You can also use the External Instrument to transmit and receive MIDI information through the instrument channel strip that it is inserted in. This enables you to control an external module—both MIDI and audio—from within one element.

To avoid constant repatching of devices, it is best to use an audio interface that supports multiple inputs and outputs. The External Instrument plug-in is inserted in instrument channel strips in place of a software instrument.
