572 Chapter 25 Mixing
To open the Mixer as a separate window:
m Choose Window > Mixer (or use the matching key command, default: Command-2).
The Mixer displays channel strips that correspond with audio and instrument (software
or MIDI) tracks shown in the Arrange area, plus the master channel, auxiliary, and
output channels. Additional channel strip types, such as busses and inputs, can also be
shown, but their inclusion is primarily for compatibility with projects created in earlier
Logic Express versions.
 Audio channel strips control audio tracks. Data on audio tracks (audio regions) is
routed to audio channels.
 Instrument channels control instrument tracks (software instrument plug-ins are
inserted into the Instrument slot of instrument channels). Data on instrument tracks
(MIDI regions) is routed to instrument channels.
 External MIDI channels control “external MIDI” tracks. Data on these tracks (also MIDI
regions) is routed to a MIDI output port and channel, for control of MIDI sound
modules and keyboards. Either the entire instrument or MIDI sub-channels can be
represented and controlled.
 Auxiliary channels act as “send/returns” or output destinations for instrument and
audio channel strips, or other auxiliary channels.
 Output channels represent the physical outputs of your audio interface, and act as a
destination for audio, instrument, and auxiliary channels.
