About
Chords Weaver is a hands-on chord instrument you play by ear.
Pick a note on the keyboard and it filters to the chords that fit. Choose one, and two pads open up: one shapes its voicing (spread, inversion, octave) while the other suggests where to go next, the right side resolving, the left adding tension. Build a progression on the timeline, and a live piano roll shows exactly what will play.
Press play and the progression comes alive with arpeggios, block grooves and strums, each chord ringing in time. Turn on Drift and the voicings slowly wander on their own, so the loop keeps evolving.
MORE
- Rich arpeggios: ascent/descent, ternary grooves (waltz, shuffle, jig 6/8), a lilting 7/4, and sparse syncopated patterns (charleston, tresillo, offbeat, push).
- MIDI Out to your synths, DAW or hardware, with a 24 PPQN clock.
- Four scenes, copy and paste, and a "roll a matching bridge" helper.
- Optional cloud save: sign in with email, Google or Apple and your progressions follow you to every device. The app works fully offline.
- Five languages: English, Français, Español, Русский, 日本語.
Free to download. Weaving, voicings, playback and saving are all free. A one-time Pro unlock adds MIDI/WAV/text export and live MIDI-out. No ads, no subscriptions. Signing in is only for optional cloud sync.

What's New in Chords Weaver
1.7.8
October 4, 2026
• Roll starts from the ghost chord: the notes you hold on the keyboard, or the chord picked in the grid, open the progression instead of a random chord. • New drift mode under the drift speed: each chord drifts on its own, or the whole progression shares one drifting voicing. • New installs open in your device's language (English, French, Spanish, Russian or Japanese), and I translated much more of the app, down to tooltips and error messages.
