About

Chords Weaver

Features
Read full description

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 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.
