ローファイの楽器 A lo-fi instrument

Matcha.

A pocket instrument for lo-fi producers.

Eight moods, chords that lead themselves, and a four-bar loop you can turn into a video. Made to be played, not configured.

Matcha's playing screen — an Am7 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 — and a one-octave keyboard lights the notes as they sound.

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.

03Record

Four bars, then a video

Play the loop, catch four bars with a single tap, and export a video where the ink blooms with every chord. Save it to Photos or send it on.

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.

Eight 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.
