MPC to control Elektron machines (Digitakt 2, Digitone 2)
License: MIT
Requires Python: >=3.12

# Elektron MCP

A Model Context Protocol (MCP) server that allows Claude and other MCP-compatible LLMs to interact with and control Elektron synthesizers via MIDI.

#### If you have a Moog Sub37/Subsequent37, check out our dedicated MCP server for it at [moog-sub37-mcp](https://github.com/zerubeus/moog-sub37-mcp).

#### A web-based version of this MCP server can be found at [senthgenie.com](https://www.synthgenie.com/). (You can ask for API key for free on discord)

#### If you want help or would like to contribute to development, please join our [Discord community](https://discord.gg/ZFuSuegBMS).

# Prompt examples

```
"Use Digitone MCP to design an evolving dark pad using the Wavetone machine on track 1."
"Use Digitone MPC to design a Dark thick pad using Wavetone machine on track 1."
```

Only Wavetone machine is supported for now, other machines will be added soon, stay tuned!

## Installation and Usage

### Prerequisites

- Python 3.10+
- [uv](https://github.com/astral-sh/uv) for package management
- An Elektron Digitone connected via USB
- Claude Desktop app (for full integration)

### Installing Dependencies

uv is mandatory for this project so start by installing it:

#### For macOS:

```bash
brew install uv
```

#### For Windows:

Follow the instructions [here](https://docs.astral.sh/uv/getting-started/installation/)

### 3. 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, all you need is to add the MCP server configuration to your claude_desktop_config.json file the MPC server is already published on pypi.

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

```json
{
  "mcpServers": {
    "Digitone 2": {
      "command": "uvx",
      "args": ["elektron-mcp"]
    }
  }
}
```

## Architecture

- **Base Controllers**: Common functionality abstracted into base classes
- **Specialized Controllers**: Dedicated controllers for each synth engine and module
- **MCP Tools**: Direct interface between LLMs and the synth's parameters
- **MIDI Interface**: Reliable communication with Digitone hardware

## Implementation Details

This library uses:

- **FastMCP**: For exposing synth controls to LLMs
- **Pydantic models**: For data validation, serialization, and type safety
- **mido**: For MIDI communication

## Use Cases

- Allow Claude and other LLMs to create and modify sounds on the Digitone
- Programmatically control Digitone parameters for automated sound design
- Bridge between AI-generated music and hardware synthesis

## Future Extensions

- Support for additional Elektron devices (Analog Four, Octatrack, etc.)
- Pattern sequencing and automation
- Sound preset management
- Additional synthesis parameters
