Ask Cursor: "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 Cursor
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

Installation Problems

Symptoms: Cursor fails to install, Application won't start

Cause: System requirements not met or corrupted download

Solution:

• Check minimum system requirements
• Re-download installer from official website
• Run installer as administrator (Windows)
• Check available disk space and permissions

MCP Settings Not Found

Symptoms: No MCP option in settings, Missing configuration section

Cause: Feature not available in current Cursor version

Solution:

• Update Cursor to latest version
• Check if MCP support is enabled in your subscription
• Look for "Extensions" or "Integrations" section instead
• Contact Cursor support for feature availability

Server Configuration Fails

Symptoms: Settings not saving, Configuration errors

Cause: Invalid server path or configuration parameters

Solution:

• Verify server executable path is correct
• Check server installation and permissions
• Use absolute paths instead of relative paths
• Test server command from system terminal first

AI Assistant Not Using MCP Tools

Symptoms: Tools available but AI not using them, Limited functionality

Cause: AI assistant not properly configured for MCP integration

Solution:

• Restart Cursor after configuration changes
• Check AI assistant settings for tool permissions
• Verify MCP server is running and responding
• Try explicitly asking AI to use specific tools

Ableton Live not appearing in Cursor

Symptoms: Server not listed, Tools not available

Cause: Configuration or installation issue

Solution:

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