InkbeatDraw a line.
Hear it.
Inkbeat is a visual instrument. A line's height is its pitch, its width is the time. You draw on paper, and the loop plays it back.

What it is
A sequencer you play with a pencil: nine instruments, a real key, a timeline of pages — and the paper is the score.
Nine voices
Keys, pluck, bell, marimba, flute, strings, chime, bass, 8-bit. Every colour is one of them, each with its own wave, filter and envelope.
A real key
Twelve keys, thirteen scales, one to three octaves, octave shift and tuning in cents. The rows of the paper are the notes of the key.
Quantize and swing
Snap to 1/4, 1/8 or triplets. Move the second of each pair with swing. Shorten notes with the length control, or let them ring.
Beats underneath
Bass, drums and an arpeggio follow the key and the tempo, so a drawing becomes a track without leaving the paper.
Pages
One to eight bars a page, pages strung into a timeline. Page turns land on the downbeat, so nothing bleeds.
Play by hand
A two- or three-octave keyboard on screen, and MIDI in from a real piano. Notes snap to the key and can be drawn into the loop.
Trace a picture
Import a photo or an SVG. The app removes the background, finds the outlines and lays them on the paper as playable ink.
Exports
WAV of the loop, MIDI of the notes, the piece as a .pmt file, and a 1080 × 1920 video take with the loop's own audio.
Nothing leaves
No account, no analytics, no ads, no tracking, and no network requests. The instrument works offline.
How it works
Three things to know, and then you are playing.
Draw
Draw with a finger, or start from a drawing in the library. Higher is higher, further right is later. Chords are wide shapes; a single dot is a single note.
Choose the sound
Pick one of the nine inks. Change the key and the paper re-rules itself. Add bass, drums and an arpeggio when the line needs a floor.
Keep it
Play the loop, turn the page, or take it out: WAV, MIDI, a video, or the piece itself to open again later.

Questions
What is Inkbeat?
A visual instrument for iPhone and iPad. You draw a line on the paper, its height sets the pitch and its width sets the time, and the app loops what you drew as music.
How much does it cost?
It is a paid app: $1.99 in the United States, with the local equivalent shown on the App Store in each country. One purchase, no subscription and no in-app purchases.
Does it need an internet connection?
