Chord Trigger MIDI plug-in
Logic Pro Chord Trigger MIDI plug-in overview
The Chord Trigger MIDI plug-in lets you trigger chords by playing a single MIDI key. The
onscreen keyboards have two functions: the display of incoming and outgoing MIDI notes
and the assignment of chords to keys. See Use the Logic Pro Chord Trigger MIDI plug-in.
Chord Trigger parameters
Single button: Assign a single chord to a trigger key. Play up and down the keyboard
to transpose the memorized chord in relation to the trigger key. This mimics the Chord
Memo or Note Stack feature found on many classic synthesizers.
Multi button: Assign a different chord to each key on the keyboard.
Upper keyboard: Shows incoming MIDI notes, represented by orange dots, and the
blue chord trigger range. Drag the handles above the keyboard to set the chord trigger
range. Notes that fall within this range are processed. Notes outside the range are not
processed. You can also click notes in the chord trigger range to trigger chords.
Lower keyboard: Shows the resulting MIDI output—the chords triggered by incoming
MIDI notes. The notes of each chord (in the chord trigger range) are displayed as
blue dots. Chords outside the chord trigger range are displayed as orange dots.
Learn button: Turn on Learn mode. See Use the Logic Pro Chord Trigger MIDI plug-in
for details on using Learn mode.
Clear button: Erase a Trigger Key note and the corresponding chord. See Use the
Logic Pro Chord Trigger MIDI plug-in for details.
Chord Octave pop-up menu: Choose an octave transposition value for chord playback.
