This walkthrough from Mastering.com dives into Logic Pro's Chord Trigger, showing how to rebuild its stock chords into your own voicings instead of settling for the presets.
Using the Learn function, you can click into any chord, strip or add notes, adjust the range, and voice lead between chords to shape a full progression by ear.
Once the chords feel right, record them straight to a MIDI track. From there you can quantize, adjust velocity, lengthen notes, or transpose, treating the generated chords as a normal editable performance.
The real payoff comes in the worked example: taking a pop preset voicing, shifting it to minor, and thickening it with an added octave and a seventh. That one move turns a decent preset into a full, spectrum-filling chord bed and an instant song idea.
