Ableton Live + oterm: Complete MCP Integration

Ableton Live is a MCP server that an MCP server to control Ableton Live..

When integrated with oterm, you can:

• Create, modify, and control audio/MIDI tracks
• Control live performance parameters and session view
• Send and receive OSC messages for real-time control

This guide provides step-by-step instructions to set up Ableton Live in oterm, including configuration, examples, and troubleshooting.

What You'll Achieve

After completing this setup:

• Ableton Live will be fully integrated and operational
• You can use Ableton Live tools directly in oterm
• All Ableton Live capabilities will be available for your workflows
• Access to 4 different tools

Prerequisites

Before starting, ensure you have:

• Python 3.8+
• Git
• Ableton Live installed
• oterm installed and configured
• Compatible operating system (CLI (Terminal))

Installation

Step 1: Install Ableton Live

Manual installation steps:

1. Install Python 3.8 or higher
2. Install uv package manager
3. Clone repository: git clone https://github.com/Simon-Kansara/ableton-live-mcp-server.git
4. Navigate to project: cd mcp_ableton_server
5. Install dependencies: uv sync

Configuration

Step 2: Configure oterm

1. Open oterm settings
2. Navigate to MCP server configuration
3. Add Ableton Live server with appropriate settings
4. Save and restart if needed

Examples

Once configured, you can use Ableton Live in oterm:

Prepare Recording Setup

Set up tracks for recording a rock band

Ask oterm: "Prepare a set to record a rock band with drums, bass, guitar, and vocals"

Expected Result: Multiple audio tracks created with appropriate input routing and naming

Configure Voice Track Routing

Set input routing for vocal tracks

Ask oterm: "Set the input routing channel of all tracks that have "voice" in their name to Ext. In 2"

Expected Result: All vocal tracks configured to receive input from external input 2

Live Performance Setup

Configure session view for live performance

Ask oterm: "Set up a live performance session with 8 tracks and 16 scenes for electronic music"

Expected Result: Session view configured with tracks and scenes ready for live triggering

Transport Control

Control playback and recording

Ask oterm: "Start recording on track 3 and set tempo to 120 BPM"

Expected Result: Recording initiated on specified track with tempo adjusted

Testing Your Setup

1. Launch oterm
2. Verify Ableton Live is available in the tools list
3. Test basic Ableton Live functionality

Troubleshooting

Common Issues

Ableton Live Not Responding

Symptoms: OSC messages not received, No communication with Live

Cause: OSC control surface not enabled or incorrect port configuration

Solution:

• Enable AbletonOSC control surface in Live preferences
• Verify OSC ports match configuration (11000/11001)
• Restart Ableton Live after configuration changes
• Check firewall settings allow OSC communication

Port Already in Use

Symptoms: Socket binding errors, Port conflict messages

Cause: Another application using configured ports

Solution:

• Check which process is using the port: netstat -tulpn | grep :65432
• Kill conflicting process or change port in osc_daemon.py
• Use alternative ports (e.g., 65433, 11002, 11003)
• Restart both server and Ableton Live

Python Dependencies Missing

Symptoms: Import errors, Module not found errors

Cause: Required packages not installed properly

Solution:

• Run uv sync to install all dependencies
• Verify Python 3.8+ is installed: python --version
• Check virtual environment is activated
• Install missing packages manually: pip install python-osc fastmcp

OSC Messages Not Routing

Symptoms: Commands not affecting Live, No response from controls

Cause: Incorrect OSC routing or message format

Solution:

• Verify OSC address patterns match Live expectations
• Check OSC message format and data types
• Test basic OSC connectivity with simple messages
• Review osc_daemon.py configuration for routing rules

Connection Refused

Symptoms: Failed to connect to Ollama

Cause: Ollama service is not running

Solution:

• Start Ollama with ollama serve
• Check if Ollama is running on the default port (11434)

Tool Not Found

Symptoms: Model does not use the tool, Tool execution failed

Cause: MCP server not configured correctly or crashed

Solution:

• Check the config.json for syntax errors
• Verify the MCP server command works independently in the terminal
• Ensure the model supports tool calling (e.g., llama3.1)

Ableton Live not appearing in oterm

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

• Verify configuration syntax
• Check Ableton Live installation
• Restart oterm
• Check logs for error messages
