Use the Chord Trigger MIDI plug-in in Logic Pro for iPad
Chord Trigger is straightforward to use: choose a mode (single or multi), set a chord trigger range, select a trigger key, then set up a chord. You can also transpose chords and quickly assign multiple chords by playing keys on your MIDI keyboard or the onscreen keyboard.
Define the chord trigger range
The chord trigger range is indicated by the bar between the Range Low and Range High sliders. Incoming MIDI notes that fall within this range are interpreted as trigger keys that play the chord (Single Chord mode) or the chords (Multi Chord mode) assigned to them. Chords can be assigned to keys within the chord trigger range. Incoming MIDI notes that fall outside the defined chord trigger range are passed through Chord Trigger unaffected. This allows you to play a melody with the right hand while triggering/transposing memorized chords with the left, for example.
In Logic Pro, drag the Range Low and Range High handles to define a keyboard range.
In Single Chord mode: Playing a MIDI note within the defined chord trigger range plays and transposes a single memorized chord. The transposition is performed in relation to the trigger key the chord is assigned to. For example, if a chord is assigned to C2, playing a D2 transposes the chord upward by two semitones. Playing a B1 transposes the chord down by a semitone.
In Multi Chord mode: Playing a MIDI note within the defined chord trigger range triggers the chord that is memorized for the played key. Keys that do not have a chord assigned to them are silent when played.
Note: If the chord trigger range is made shorter, memorized chords that fall outside the range become inaccessible but are not deleted. Lengthening the chord trigger range makes assigned chords accessible again.
Transpose chords in the chord trigger range (Multi Chord mode only)
You may want to transpose triggered chords in some circumstances. For example, in Multi Chord mode you can move the entire chord trigger range upward by two semitones to change a chord progression in C-Major (starting with the C trigger key) into a progression that plays in D-Major, starting with the D trigger key.
In Logic Pro, drag the center of the chord trigger range left or right.
All memorized chords are moved with the chord trigger range and are automatically transposed.
Transpose chords by semitones or octaves
In Logic Pro, use the Chord Transpose knob to set a value.
All memorized chords can be transposed up or down by up to four octaves.
Assign a chord to a key
In Logic Pro, tap the Learn button.
Choose a trigger key—within the chord trigger range— from either the Trigger Key pop-up menu or by playing a key on the onscreen keyboard or your MIDI keyboard.
Play the chord you want to assign to the trigger key on the onscreen keyboard or your MIDI keyboard.
To end chord assignment, tap the Learn button.
You can repeat these steps to assign a different chord to each key in the chord trigger range when in Multi Chord mode. In Single Chord mode, only one chord can be learned.
Clear a chord assignment
In Logic Pro, choose the key from the Trigger Key pop-up menu, then tap the Clear button.
Clear all chord assignments
The following applies only to Multi Chord mode.
In Logic Pro, tap the Clear All button.
All chords on all trigger keys are erased.
