Features

A musician's ear for harmony, inside your DAW.

Chordable Pro listens to what you play and answers with the chords a skilled arranger would choose, voiced and led from one chord to the next.

01 — Live

Play one line. Chordable plays the rest.

Play your MIDI keyboard and choose which voice you are, from soprano down to bass. Chordable hears every note and answers with a full five-part chord, choosing the next harmony as your melody moves.

  • Five input roles, or let Chordable decide
  • Chord changes that follow your melody
  • Voicings that adapt as you play
Live mode: a chord history of Bb7, Dm7b5, Gm7/D, Cm/G, Bb7/F and Ebmaj7, with each chord's five voices drawn as bars on a pitch grid.
02 — Progression

Plan a progression. Keep what you love.

Generate 4 to 32 bars that follow your host's tempo and metre. Lock the chords you like, regenerate the rest, and shape rhythm, texture and modulation in a click.

  • Per-chord locks and replacement
  • Rhythm, voices and modulation controls
  • Edits land on the next bar or beat, without stopping playback
Progression mode: four bars of C, Dm/F, Bdim/D, C/E, Dm, G and C, with the first chord locked and the playhead on C/E.
03 — Harmony

A harmonic vocabulary with real character.

Forty-three profiles, grouped the way musicians think about harmony. Pick triads or sevenths, closed, open or spread spacing, and how much spice to add.

  • Major
  • Dorian
  • Lydian Dominant
  • Harmonic Minor
  • Octatonic
  • Blues & Bebop
  • Songwriter
  • Baroque
  • Classical
  • Romantic
  • Late Romantic
  • Impressionist

04 — Melody & MIDI

Add a melody. Drag it all into your session.

Chordable can write a melody over the progression, then hand everything to your DAW. Drag the chords out as a single MIDI part, or all five voices as separate parts, and carry on with your own instruments.

  • Melody line written over the planned harmony
  • Drag-and-drop MIDI: chords or five voices
  • Built-in orchestral sounds for instant playback

Voice leading

Every voice goes somewhere.

Chordable writes in five real parts, from bass to soprano. Each one moves to the nearest good note, the way a composer would write for a choir or a string section.

Orchestral sounds built in

Sampled strings, winds and brass, balanced like an orchestra, plus lightweight synths for sketching.

Real-time by design

Live harmony is worked out as you play, so chords arrive with your note. Longer plans are prepared in the background without interrupting playback.

Private and offline

Everything runs on your computer. No account, no cloud processing, no internet connection needed.
