Mission Control

Launch clips and control Ableton Live from any browser. Inspired by the legendary Novation Launchpad. See the User Manual for detailed usage instructions.

Features

• Transport Control — Play, stop, record, tap tempo, punch in/out, loop toggle
• Clip Launching — Fire and stop clips with quantization support (1/32 to 8 bars)
• Scene Launching — Trigger entire scenes with one click
• Track Controls — Mute, solo, and arm per track
• Drag & Drop — Move clips between tracks with automatic type validation
• Real-time Sync — Instant bidirectional updates between Ableton and the UI
• Visual Feedback — Color-coded clips, playback progress indicators, playing states

Quick Start

1. Download

Platform	Download
macOS (Apple Silicon)	Mission.Control.Bridge-aarch64.dmg
macOS (Intel)	Mission.Control.Bridge-x64.dmg
Windows	Mission.Control.Bridge-x64-setup.exe

Or try the edge build for bleeding edge updates on every commit.

2. Install the Remote Script

Launch Mission Control, then click the tray icon → Install Remote Script.

Or manually: download AbletonOSC and copy the AbletonOSC folder to:

• macOS: ~/Music/Ableton/User Library/Remote Scripts/
• Windows: ~\Documents\Ableton\User Library\Remote Scripts\

3. Enable in Ableton

In Ableton Live, go to Preferences → Link, Tempo & MIDI → Control Surface and select AbletonOSC.

4. Connect

Open a Live Set, then click the tray icon:

• Open Mission Control — Opens the UI in a browser on this computer
• Connect on Mobile — Shows a QR code to connect from a phone or tablet on the same network

The connection status indicator will turn green when connected.

Requirements

• Ableton Live 10, 11, or 12
• macOS or Windows

Troubleshooting

"Waiting for Ableton Live"

• Ensure Ableton Live is running with a project open
• Check that AbletonOSC is selected in Preferences → Link, Tempo & MIDI → Control Surface
• Try restarting Ableton after installing the remote script

AbletonOSC not appearing in Control Surface list

• Make sure the folder is named exactly AbletonOSC (no version number)
• Restart Ableton Live completely after copying the folder
• Verify the script is in your User Library's Remote Scripts folder. Find your User Library location in Ableton: Preferences → Library → User Library

Controls not responding

• Check that AbletonOSC is still selected in Control Surface preferences
• Try refreshing the browser page
• Restart Ableton Live

• Protocol: OSC via osc-js

How It Works

Mission Control acts as a bridge between your browser and Ableton Live:

Browser ←—WebSocket—→ Bridge Server ←—OSC—→ Ableton Live (AbletonOSC)

The bridge server translates WebSocket messages to OSC commands and vice versa, enabling real-time control from any modern browser.
