Protocol 0
the forgotten Ableton key mapper

A better keymapper for Ableton Live 12.

Ctrl + Shift + P
What it does

A super flex keymapper… and more

Persistent hotkey mapping

Your shortcuts survive across sets — set them once, keep them forever.

Modifier support

Build real key combos with Ctrl, Alt and Shift.

Additional smart actions

Beyond basic mappings, use smart actions like loading a device or selecting a track by name — not by counting clicks.

Web UI to configure shortcuts

Map, edit and review everything from a clean browser interface.

HTTP API to control Live

Plug your own tools to trigger actions (Stream Deck, custom scripts)

Free, open source & extensible

MIT-spirited and built to be forked, scripted and extended (See Github repository for details).

Installation

Up and running in minutes

Launch the installer, activate the Protocol 0 remote script in Ableton and configure your shortcuts at http://localhost:9000

How does it work?
