Polychord turns your iPad into a chord instrument — a full band at your fingertips. Nine chord circles hold every chord in your key — arranged so the right one is always under your fingers. Tap a circle to hear it, and the ring around it offers the colors: sevenths, sixths, suspensions. Strum across the keys like a harp. You can't hit a wrong note, and you never have to stop and think. Flip on Auto Accompany and a rhythm section falls in behind you: bass and drums that follow every chord change you make, in styles from folk to funk to krautrock. One finger becomes a band. When something good happens, hit record. Loop, layer, and bounce it to audio, or export multi-track MIDI with chords, strum, bass, arpeggiator, and drums on separate tracks, ready for your DAW. In the studio, Polychord comes with you. The AUv3 MIDI-effect plugin puts the chord grid inside DAWs like Logic Pro that support MIDI effects, and MIDI in and out means it can play — or be played by — everything else you own. Whether you've played for twenty years or never learned an instrument, Polychord closes the gap between imagining music and making it. FEATURES • Nine chord circles covering the full harmony of any major or minor key • Chord palettes for folk, jazz, gospel, bossa nova, soul, cinematic, and more • Strum keys with pitch bend • Auto Accompany: bass lines and drum patterns that follow your chords • Arpeggiator with adjustable direction, rate, and octave span • Built-in wavetable synth with ADSR envelopes, filter, delay, and bitcrusher • Record performances and bounce to audio • Multi-track MIDI export: chords, strum, bass, arpeggiator, and drums on separate tracks • MIDI out to any app or hardware; MIDI in to trigger chords from a keyboard • You can even split your MIDI output to trigger multiple instruments at once in DAWs like Logic • AUv3 MIDI-effect plugin: play the chord grid inside your favorite host • AUv3 works in DAWs like Logic Pro that support MIDI effect plug-ins Polychord is a one-time purchase. No subscription, no in-app purchases, no account. Your music stays yours.
