Working with MIDI Channel Strips in the Mixer
This section deals with the MIDI channel strips of the Mixer, as well as those of the
GM Mixer (see
GM Mixer Objects ).
The MIDI channel strips work as remote controls for the mixing parameters of your
MIDI-controlled sound modules and synthesizers, such as volume and pan.
Note: The controls send MIDI control change messages. They do not control any audio
signal flow within Logic Express.
