Matcha's playing screen — an Am9 chord above a lit keyboard, ink blooming behind it

Matcha began with a small wish: to make a lo-fi loop feel like sitting down and playing, not opening a session. No timeline, no plugins, no theory. A few chords that fall into place, and an ink that moves when you do.

The instrument

Play by feel.

01Play

Chords that lead themselves

Tap a quality, drag the voicing open or closed. Every change is voice-led, so a progression holds together without you thinking about it. The keyboard lights the notes as they sound: one octave on iPhone, two on iPad.

02Sound

Shape the tone

Rhodes, pads, bells and organ, plus a sampler. Bass that walks or holds the root, drums with real swing, reverb and chorus to soften the edges.

03Share

A loop, then a video

Export a video where the ink blooms with every chord, and save it to Photos or send it on. Recording your own four bars is part of Studio.

04Quiet

Calm on purpose

A reactive ink-wash background that moves with the music, a dark room that stays out of the way, and a Live Activity on the Lock Screen and Dynamic Island.

Twelve packs

A whole kit in one tap.

Each pack fixes the synth, bass, drums, swing, tempo, chord palette and colour. Choose a mood and begin — change it whenever you like. Eight to start with; four Signature Packs come with Studio.

Matcha Studio

From a good loop to a finished piece.

One purchase, yours forever — no subscription and no account. Try it before you buy: the app plays a built-in demo song, and Matcha Magic will arrange your own four bars into a whole track as many times as you like. Studio is for keeping it.

01Magic

Four bars in, a song out

Pick a mood and Matcha lays out an intro, verses that build, a lift and an outro — drums, bass and ink all following the energy of each section. Listen to as many takes as you like; Studio saves the one you want.

02Song Mode

Build the whole track

Reorder, duplicate and rename sections, set how hard each one hits, and swap the loop underneath. Playback crosses section boundaries without a gap.

03Journey

Never guess the next chord

Three directions from wherever you are — stay chill, add tension, or take me home. Pick a feeling instead of a chord name.

04Packs

Four more worlds

Rainy Taipei, Dusty Cassette, Bedroom R&B and Night Train — each a complete kit with its own curated progressions. You can hear any of them before you buy.

05Export

Take it with you

Record your own four bars, then export a MIDI file (chords, bass and GM drums on their own channels), audio stems, or the whole song. Matcha also installs as an AUv3 instrument — Matcha: Chord Synth — so you can play the same voices inside GarageBand, Logic, AUM or Cubasis.
