The Studio
Choose the paper, the key, the scale, the tempo and the nib, then draw. A mixer sits behind the sheet for the balance between voices. Apple Pencil works, including the squeeze to change ink.
Draw a line. Hear it play.
Cue is a sheet of paper that plays what you draw. Lines are melodies, taps are drums, and every colour is a different instrument. No notation, no grid to fight — just a pen and a page that loops.

Four things to learn, and then you know the whole app.
Draw a line across the paper.
The line becomes a part, and the part loops. Keep drawing on top of it and the arrangement grows underneath your hand.
Higher lines play higher notes.
The page is the pitch. Everything lands in the key and scale you chose, so a shape drawn badly still sounds right.
Tap the paper for a drum beat.
Taps snap to the grid — eighths, sixteenths or thirty-seconds — so a rhythm tapped roughly comes back in time.
Each colour is an instrument.
Eight riso inks: bass, pluck, pad, lead, keys, bell and two drums. Switch ink and the next line you draw is a different sound.
Where lines cross, you hear harmony.
Two inks overprinting on paper make a third colour. Two lines crossing on the sheet make a chord. The drawing and the music are the same object, so you can see what you are about to hear.
What's inside
Sing a photo
Point at a thing in a photo — a hill, a cat, a skyline — and its outline becomes a print you can play and keep drawing on. On supported devices the arrangement is planned by Apple's on-device model. The photo never leaves your iPhone.
Inks you record yourself
Record a few seconds with the microphone, or bring in a file, and it becomes an ink in the strip. Melodic samples play across the page; one-shots land at their own pitch. Give it any colour you like.
Press a video
Every print exports as a square or vertical video: the sheet, the playhead sweeping, and the sound already mixed in. Save it to your camera roll or send it straight to TikTok and Instagram.
Let's make wonderful music together.
