256 Chapter 10 Working With Instruments and Effects
Adding Program Change, Volume, and Pan Settings to a MIDI Region
The MIDI > Insert Instrument MIDI Settings as Events command allows you to insert the
program change, volume, and pan settings (from the Track Parameter box in the
Inspector) as actual MIDI events into one, or more, selected MIDI regions. The events
are placed a quarter note before the beginning of the relevant MIDI regions. Only the
activated (checked) settings in the Track Parameter box(es) are added as events. If any
events of the same kind already exist in the region(s), they are overwritten.
The values of the Program, Volume, and Pan parameters will not be updated every time
such control change events are played back. These parameters are initial values, when
you load a project, or choose the MIDI > Insert Instrument MIDI Settings as Events
command—before you begin to record mixer automation data.
Processing External MIDI Instruments With Effects
You can route external MIDI sound generators through the Logic Express Mixer,
allowing you to process them with Logic Express effects. This is achieved through use
of the External Instrument plug-in. Ideally, you will use a multi input and output audio
interface, to avoid constant re-patching of devices.
To process external MIDI instruments with effects:
1 Connect the output (or output pair) of your MIDI module with an input (pair) on your
audio interface.
Note: These can be either analog or digital connections if your audio interface and
effects unit are equipped with either, or both.
2 Create an instrument channel.
3 Click the Instrument slot, and choose External Instrument from the pop-up menu.
4 Choose the MIDI Destination from the menu in the External (instrument) plug-in
window.
The MIDI Destination menu will show all sub-channels of all multi instruments in the
Environment.
5 Choose the input (of your audio interface) that the MIDI sound generator is connected
to from the Input pop-up menu.
6 Adjust the Input Volume, if necessary.
7 Insert the desired effects in the Insert slots of the channel.
