MIDI is a note and melody workstation for the browser. You draw MIDI for several instruments. Then you export one `.mid` file for each instrument to your DAW. The [app walkthrough](https://www.youtube.com/watch?v=4g8Wd1woGKY) shows the workstation in three minutes.

Every instrument stays on screen at once, as overlaid ghost notes or as stacked lanes. An 88-key view lights the notes at the playhead and names the current chord.

A harmony lane holds the chords, and those chords drive the rest of the app. As the pencil moves over the grid, the app ranks possible notes and gives a reason for each. The key panel has 26 scales and modes, key detection, and a circle of fifths.

Generators write chord progressions, melodies, and basslines in the current key. An arpeggiator has 13 patterns with a live preview.

The app imports `.mid`, `.midi`, and `.zip` files and splits multi-track files into one instrument each. It exports separate files, a ZIP bundle, one multi-track file, or files directly into a folder.

Workspaces save automatically in the browser. In Chromium browsers, Web MIDI connects a controller keyboard and sends any track live to another app.

MIDI installs as a PWA and works offline after the first load.
