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

Extension Not Loading

Symptoms: Cline extension not appearing, Command palette empty

Cause: Extension installation or VS Code configuration issue

Solution:

• Verify extension is properly installed via Extensions panel
• Check VS Code version compatibility
• Reload VS Code window or restart application
• Check VS Code developer console for error messages

MCP Server Not Found

Symptoms: Server command not found, Tools unavailable in Cline

Cause: Server not installed or not accessible from VS Code

Solution:

• Verify MCP server installation and PATH configuration
• Test server command from VS Code integrated terminal
• Use absolute path to server executable in configuration
• Check server executable permissions

Configuration Not Applied

Symptoms: Settings changes not taking effect, Old configuration persisting

Cause: VS Code settings not reloaded or invalid configuration

Solution:

• Reload VS Code window after configuration changes
• Verify JSON syntax in settings.json is valid
• Check Cline extension settings panel for errors
• Review VS Code developer console for configuration warnings

Tool Execution Fails

Symptoms: MCP tools available but not working, Error during tool execution

Cause: Server configuration or environment issues

Solution:

• Verify environment variables are set correctly
• Check server logs for execution errors
• Test server functionality outside of VS Code
• Ensure all required dependencies are installed
