Logic Pro studio instruments section MIDI
channels
In section presets, each instrument uses a dedicated MIDI channel. This enables you
to play specific instruments in a section by sending MIDI messages on their respective
channels. Similarly, if you create a region for a section instrument, you can assign
each MIDI event a specific MIDI channel to ensure that it is played only by a particular
instrument within the section.
• MIDI channel 1 is always the “section” channel, meaning that it is used to play the entire
section, either via Auto Voice Split, or as a Layer/Key Split, depending on the plug-in
setting.
• MIDI channel 2 and above are used to access the different instruments of a section
directly.
Note: When the Inst via MIDI Channel checkbox in the Extended parameters is turned off,
the full section is played on any incoming MIDI channel. Active Unison / Auto Voice Split /
MIDI Split settings apply. Full section playback is also triggered by incoming MIDI channel
data that is not used in the section.
