What is the EP-133 K.O. II MCP Controller?

This is an intelligent interface that controls the EP-133 K.O. II music device through natural language interaction with Claude AI. You can describe your musical ideas in everyday language, and the system will automatically convert them into MIDI instructions and send them to the device.

How to use this controller?

Simply connect the device to your computer and enter musical instructions in the Claude chat interface. For example, 'Play a C major scale' or 'Create a 1-3-5 drum rhythm'.

Applicable scenarios

Suitable for quick inspiration testing during music creation, on - site performance control, music teaching demonstrations, and remote control scenarios when it is inconvenient to directly operate the device.

Main features

Intelligent device connection

Automatically identify connected EP-133 devices and support multi - device switching

Natural language control

Describe your musical ideas in everyday English, and they will be automatically converted into professional MIDI instructions

Intelligent drum kit programming

Supports four ways of sound reference and rich rhythm syntax, and can create complex rhythm patterns

Sound browser

Browse the device's preset sound library and find the desired sounds by category

Advantages

No need to learn complex MIDI protocols, and you can create music using natural language

Support simultaneous control of multiple sound voices

Provide intelligent retrieval function for the device's sound library

Seamlessly cooperate with other creative functions of Claude AI

Limitations

Requires USB connection to a physical device

Complex rhythms may require adjusting BPM parameters

Some advanced MIDI functions still need to be implemented by professional DAWs

How to use

Install software

Ensure that Python 3.8+ is installed, and then install the required dependencies via pip

Connect the device

Connect the EP-133 K.O. II to your computer using a USB cable and turn on the device's power

Start the service

Run the MCP server in the project directory. It is recommended to use the development mode for easy debugging

Start creating

Enter musical instructions in the Claude chat window, such as 'Create a drum rhythm with syncopation'

Usage examples

Basic scale practice

Quickly test the device's scales and sounds

Drum kit creation

Create complex multi - voice drum rhythms

Sound exploration

Discover the special sound effects built into the device

Frequently asked questions

🚀 MCP Interface for Teenage Engineering EP-133 K.O. II

This project is a Model Context Protocol (MCP) server designed to control the Teenage Engineering EP-133 K.O. II sampler via MIDI.

🚀 Quick Start

The MCP server in this project enables users to control the Teenage Engineering EP-133 K.O. II sampler through MIDI, offering a convenient way to play music and create drum patterns.

✨ Features

Connect to your EP-133 K.O. II device via MIDI.
Play notes and patterns using text commands.
View the default pad configuration to understand sound mappings.
Create and play drum patterns using a simple text-based syntax.
Support multiple instrument reference methods (pad labels, MIDI pitches, instrument names, sound names).
Play drum patterns of multiple instruments simultaneously.
Integrate with Claude via MCP.

📦 Installation

Prerequisites

Python 3.8 or higher.
mido (for MIDI processing).
mcp (Model Context Protocol SDK).

Quick Installation

# Install the required packages
pip install mido "mcp[cli]"

# Clone the repository
git clone https://github.com/benjaminr/mcp-koii.git
cd mcp-koii

# Install the MCP server
mcp install koii_server.py:server -e .

💻 Usage Examples

Using with Claude Desktop

Ensure your EP-133 K.O. II is connected to your computer via USB.
Launch Claude Desktop with MCP support.
Control your EP-133 K.O. II by asking natural language questions to Claude:
- "List available MIDI ports."
- "Connect to the EP-133 device."
- "Play a C major scale."
- "Play a drum pattern with bass on beats 1 and 3, snare on 2 and 4, and hi-hat on every eighth note."

Running in Development Mode

You can run the MCP server in development mode for testing without Claude Desktop:

# Run with the inspector UI
mcp dev koii_server.py:server -e .
