Builds chord progressions from any key and writes the result as a MIDI clip, with two distinct harmony modes for different musical styles.

Features

• Progression II — Functional jazz grid ordered for common progressions (I–vi–IV–ii–V–iii–vii), showing secondary dominants, diatonic chords, and borrowed chords per column
• Dark Harmony — Chromatic grid built around the natural minor scale with augmented, diminished, and Neapolitan colors
• Queue and write — Click chords to build a progression queue, then write the result as a MIDI clip
• Smart placement — Clip is placed in the first empty slot on the right-clicked track

How to use

1. Right-click any MIDI Track and choose Create Chord Progression….
2. Select a key and harmony mode.
3. Click chords in the grid to add them to the progression queue.
4. Click Write to MIDI Clip to create a new MIDI clip.

Each chord is written as four simultaneous notes (close voicing, whole-note duration, velocity 80) with one bar per chord. The clip is named with the chord symbols joined by " – " (e.g. Cm7 – F7 – Bbmaj7).
