594 Chapter 25 Mixing
Master Channel
The master channel strip changes the gain of all output channels. It acts as a separate
attenuator stage; the level relationships between output channels are not affected. This
is very helpful as a proportional output volume control.
In some cases, you might want to prevent individual output channels from being
controlled by the master channel—outputs used as effect sends to external hardware
devices, for example. Simply switch such output channels to Solo Safe mode by
Control-clicking their Solo button, and they won’t be affected by the master channel.
Moving the master channel fader does not affect the position of output channel faders,
but rather, the signal levels directly. These level changes are reflected in the level
meters of each output channel.
∏
Tip: The Transport bar also offers a master fader. This is a remote control for the master
channel strip shown in the Mixer, which allows quick and easy control of the overall
level from the Arrange window.
MIDI Channel Strips
This section deals with the MIDI channel strips of the Mixer, as well as those of the GM
Mixer (see “
GM Mixer ” on page 911).
The MIDI channel strips work as remote controls for the mixing parameters of your
MIDI-controlled sound modules and synthesizers (volume and pan, for example).
Important: The controls send MIDI Control Change messages. They do not control any
audio signal flow within Logic Express.
