Overview

What is Flstudio?

Flstudio is an MCP server that connects Claude (an AI assistant) to FL Studio, enabling Claude to generate and send MIDI data to FL Studio via virtual MIDI ports. It uses a custom MIDI controller script (device_test.py) and a Python server (trigger.py) to communicate.

How to use Flstudio?

Download the server files, place the Test Controller folder in FL Studio's Hardware settings directory, configure Claude Desktop with the trigger.py as an MCP server, install LoopMIDI (Windows) or use auto-setup (Mac), create a virtual MIDI port, set FL Studio's MIDI input to that port with controller type "Test Controller", install required Python packages (httpx, mido, python-rtmidi, etc.) via uv pip install, and then tell Claude to get available MIDI ports. After verifying the connection, Claude can send notes to the active FL Studio instrument.

Key features of Flstudio

  • Connects Claude AI to FL Studio via MCP.
  • Uses virtual MIDI ports for real-time communication.
  • Live records MIDI notes to the piano roll of the selected instrument.
  • Encodes note data in multiple 7-bit MIDI messages.
  • Open‑source, community‑driven development on Discord.

Use cases of Flstudio

  • Composing melodies, chords, and drum patterns using natural language prompts.
  • Generating MIDI sequences and sending them directly to FL Studio.
  • Experimenting with AI‑assisted music production without manual MIDI programming.

Frequently asked questions

1

What does the Flstudio MCP server do?

It allows Claude (or any MCP client) to send MIDI notes, velocity, length, and position data to FL Studio, which then live records them to the active instrument's piano roll.

2

What dependencies are required to run Flstudio?

On Windows you need LoopMIDI (for virtual MIDI ports) and Python packages: `httpx`, `mido`, `python-rtmidi`, `typing`, `fastmcp`, and `FL-Studio-API-Stubs`. You also need `uv` and a conda environment.

3

Where does the MIDI data live?

Data is sent as real‑time MIDI messages through a virtual port. No persistent storage is used; notes are directly recorded into FL Studio.

4

What known limitations does Flstudio have?

MIDI communication is limited to 7‑bit values (0–127), so note positions and lengths must be encoded across multiple MIDI messages. The server relies on FL Studio's controller API, which may restrict deeper DAW integration.

5

How is the Flstudio server connected to Claude?

You set up the `trigger.py` file as an MCP server in your Claude Desktop configuration (`claude_desktop_config.json`) following the standard MCP quickstart guide.
