Set the channel strip output format in Logic Pro
Logic Pro can automatically determine the output format of specific channel strip types.
You can override the automatic choices by manually setting the output; otherwise, the
channel strip output formats follow these rules:
Audio channel strips: The channel strip of an empty audio track is automatically set to
the format of the first audio file added to it. If you add an audio file to a track assigned
to a different output format (adding a stereo file to a track routed to a surround output,
for example), the audio file is automatically upmixed or downmixed to match the output
format of the channel strip.
Note: The highest possible surround format is determined by the project surround
format. See Set the surround format for a Logic Pro project.
Instrument channel strips: Instrument channel strips automatically adopt the channel
format of the inserted instrument.
If you insert a stereo instrument, the channel strip output will be stereo.
If you insert a surround instance of a software instrument (ES2 or Sculpture, for
example), the channel strip output will match the project surround format.
Aux channel strips: Automatically created aux channel strips adopt the format of their
input source (if a stereo channel is routed to an aux channel strip, the aux will be
stereo). If you manually change the output format of an aux channel strip, LogicPro
automatically:
Inserts a Surround Balancer or a mono/stereo to surround panner, if you are
changing the output of an aux from mono to stereo or mono/stereo to surround. See
Logic Pro Surround Panner overview.
Downmixes the signal to the required format.
If you don’t want to work with the automatic settings, you can manually set the output of all
audio, instrument, aux, and output channel strips to the chosen project surround format.
