What is Moog Sub37 Mcp

moog-sub37-mcp is a Model Context Protocol (MCP) server designed to enable interaction between Claude and other MCP-compatible LLMs with the Moog Sub37/Subsequent37 analog synthesizer via MIDI. This server facilitates AI-assisted sound design and parameter control for this iconic synthesizer.

Use cases

Use cases for moog-sub37-mcp include designing unique sound patches, creating complex sequences, programming arpeggiated patterns, and automating sound parameters in real-time for performances or recordings.

How to use

To use moog-sub37-mcp, ensure you have Python 3.12+, the uv package for management, and a Moog Sub37 or Subsequent37 synthesizer connected via USB. You will also need the Claude Desktop app for full integration. Start prompts with ‘use Moog sub37 MCP to …’ followed by your desired sound design task.

Key features

Key features of moog-sub37-mcp include a complete MIDI control interface for all Sub37/Subsequent37 parameters, support for both synthesizer models, access to all synthesis parameters (oscillator controls, filter controls, envelope generators, LFO settings, modulation routing, arpeggiator/sequencer parameters), preset management, and real-time parameter automation.

Where to use

moog-sub37-mcp can be used in music production, sound design, live performance, and educational contexts where interaction with the Moog Sub37/Subsequent37 synthesizer is desired.

Moog Sub37 MCP

A Model Context Protocol (MCP) server that allows Claude and other MCP-compatible LLMs to interact with and control the Moog Sub37/Subsequent37 analog synthesizer via MIDI. This integration enables AI-assisted sound design and parameter control of this legendary Moog synthesizer.

About the Moog Sub37/Subsequent37

The Moog Sub37/Subsequent37 is a powerful analog synthesizer featuring:

• 2 oscillators with sub oscillators
• Classic Moog ladder filter
• Dual LFOs
• Extensive modulation options
• 256 preset memory
• 37-key keyboard with velocity and aftertouch
• Mono and Duo (paraphonic) modes
• Built-in arpeggiator and step sequencer

Prompt Examples

Prompt should start with “use Moog sub37 MCP to …”

"Design a deep, resonant bass patch using the Moog filter's self-oscillation on midi channel 3"
"Create an evolving pad sound using both oscillators in Duo mode on midi channel 3"
"Program a sequence that showcases the Sub37's classic Moog lead sound on midi channel 3"
"Design a dark atmospheric sound using the Sub37's modulation capabilities on midi channel 3"
"Create a punchy bass sound perfect for techno using the multidrive circuit on midi channel 3"

Installation and Usage

Prerequisites

• Python 3.12+
• uv for package management
• A Moog Sub37 or Subsequent37 synthesizer connected via USB
• Claude Desktop app (for full integration)

Installing Dependencies

uv is mandatory for this project. Start by installing it:

For macOS:

brew install uv

For Windows:

Follow the instructions here

Installing with Claude Desktop

To use with Claude AI, add the MCP server configuration in Claude Desktop:

⚠️ Important: You don’t need to clone the repository or install the packages manually. The MCP server is published on PyPI and can be installed automatically.

Go to Claude > Settings > Developer > Edit Config > claude_desktop_config.json to include the following:

{
  "mcpServers": {
    "Sub37": {
      "command": "uvx",
      "args": [
        "moog-sub37-mcp"
      ]
    }
  }
}

Implementation Details
