// What Chord Spire does

Write the part. Without leaving the studio.

Chord Spire lives on its own Array Studio track, with its own fader, pan, automation and effect inserts. It follows tempo changes and renders sample-for-sample identical every time.

🎹

Every chord on one page

Pick a root and one of 32 chord types on the pads. KEY FILTER marks the ones that leave the key, and FOLLOW KEY moves everything to your session key.

One chord per bar, as blocks

Chords live as 1-bar blocks on the timeline. Move, copy and split them; the melody moves with its chords. Drag chords onto any MIDI track.
