98 Chapter 4 Setting Up Your System
Using External MIDI Devices
Logic Express recognizes all MIDI devices set up in the Audio MIDI Setup (AMS) utility,
the integrated audio and MIDI configuration tool of Mac OS X. You can find the AMS
utility in the Applications/Utilities folder. For more information on use, see the AMS
Help.
The Library tab displays all MIDI devices found by the AMS utility (separated into MIDI
channels, if multi-channel devices) when an External MIDI track is selected. You can
simply select the desired MIDI device/sub-channel to assign it to the track.
You can configure external MIDI devices in the Inspector. For more information, see
“Standard Instruments” on page 899, “Multi Instruments” on page 901, and “Mapped
Instruments” on page 907.
Using External Audio Effects
If you want to send audio to an external (MIDI controlled) audio effect device, you need
to insert the In/Out plug-in into one of the Insert slots of the audio channel you want
to process. For further information, see “Working With External Audio Effects” on
page 261.
Note: It is only practical to use the In/Out plug-in for external device routing when you
have an audio interface equipped with multiple in and out ports.
