Chords under your thumb. maxChord turns chord progressions into something you play with one hand. The pads are laid out in whatever key you choose, so everything you touch is already in tune. Tap one to play it. Hold it and drag, and the chord morphs — sevenths, sus, diminished, extensions — each one a direction rather than a menu. Common notes keep ringing while the rest move, so a progression bends instead of jumping. Then build the song. PLAY • Eight chord pads, in key, labelled with roman numerals • Drag any pad in eight directions to morph it live • Chord Lock keeps a variation as the pad's new resting chord • Inversions, slash chords, and automatic voice leading • Three modes: Chords, Arpeggiator, and Lead SEQUENCE • Multi-track sequencer built from chord tiles, not a note grid • Split, resize, and drag tiles to build rhythm by feel • Sixteen patterns, chained into sections to arrange a whole song • Per-track instrument, octave, volume, arpeggiator rate, and effects • Record from the pads or from a MIDI controller in real time SOUND • Sampled instruments: grand piano, upright, Rhodes, Wurlitzer, vibraphone, harp, strings, brass, nylon guitar, church organ, and choir • A fifteen-voice analogue synth bank with real filter envelopes and oscillator detune • Eight effects — drive, filter, chorus, flanger, phaser, tremolo, delay, reverb — per track and across the whole mix, each swept with a single thumb CONNECT • MIDI in and out, including per-track output • Clock sync in both directions • Play maxChord from a controller, or drive Logic, Ableton, or GarageBand from it maxChord has no account, no ads, and no analytics. It does not collect your data, and it works entirely offline. Your songs live on your device and can be exported to a single file whenever you want them somewhere else. Made for people who hear the chord before they can name it. — maxChord Pro unlocks everything after a 3-day free trial: €1.99/month, €9.99/year, or €22.99 once for lifetime access.
