MCP MIDI Bridge
Overview
MCP MIDI Bridge is an Electron-based desktop application that acts as a bridge between LLM-driven music generation (via the Model Context Protocol, MCP) and any DAW (Digital Audio Workstation) that accepts MIDI input. It enables AI-generated or AI-edited musical content (in Magenta NoteSequence JSON format) to be easily played, recorded, and manipulated in a DAW via a virtual MIDI device.
This project has been recently refactored to use a modern technology stack, including Next.js for the user interface and TypeScript for the entire codebase.

Features
MCP API Server: An Express-based server that receives and updates musical content (NoteSequence JSON) from LLMs via HTTP.
Virtual MIDI Output: Creates a virtual MIDI device that any DAW can connect to, powered by
easymidi.Multi-Channel Support: Full support for all 16 MIDI channels with General MIDI instruments.
Configurable Port: Run multiple instances on different ports for parallel workflows.
Song Cache: Stores song data for persistence between sessions.
User Dashboard: A modern, responsive UI built with Next.js and React, for viewing and playing songs.
MIDI Import/Export: Support for importing and exporting MIDI files (coming soon).
TypeScript Codebase: The entire project is written in TypeScript for improved type safety and maintainability.
Technology Stack
Electron: Cross-platform desktop application framework.
Next.js: React framework for building the user interface.
TypeScript: Superset of JavaScript that adds static types.
Express: Web framework for creating the MCP API server.
EasyMIDI: Library for creating virtual MIDI devices.
