MIDI JSON Bridge

An Ableton Live extension that exports/imports MIDI clip notes as JSON. It's designed for workflows where melodies or chord progressions are generated/edited as JSON in a chat with Claude (or similar tools) and then applied to a clip in Live.

Features

Single clip

• Export as JSON: Right-click a MIDI clip → note data (pitch, startTime, duration, velocity, muted) is shown as JSON in a modal dialog, ready to copy to the clipboard.
• Import from JSON: Right-click a MIDI clip → paste JSON and click "Apply" to replace the clip's notes.

Whole track (Session View)

• Export track clips as JSON: Right-click a MIDI track → every clip in its session clip slots is collected into one JSON document.
• Import track clips from JSON: Right-click a MIDI track → paste JSON. For each entry, the clip in the matching slot is overwritten (or created if the slot is empty) with the given name and notes.

JSON format

See docs/json-format.md for the full specification of both the single-clip note array and the whole-track document, including field reference, import/export behavior, and examples.
