Channel Strip Types
Channel strips are the building blocks of the Mixer. In the following section, you will
learn about the differences between channel strip types, and how you can use them.
Audio Channel
The audio channel strip is used for playback and recording of the audio signals (in
regions) on Arrange window audio tracks. You can control all sonic elements of audio
tracks with the audio channel strip.
Instrument Channel
The instrument channel strip allows you to use, and control, software instruments in
Logic Pro. Currently, the included Logic Pro and GarageBand software instruments and
Audio Unit compatible instruments, including the QuickTime synthesizer (DLS Music
Device) are supported.
Logic Pro allows the simultaneous use of up to 255 discrete instrument channel strips,
dependent on available CPU resources and system RAM.
The Instrument slot of the instrument channel (just above the Output slot) serves as
the insert point for software instruments. Simply click on the Instrument slot and
choose the name of the instrument plug-in from the menu.
