## Description

MCP MIDI Server creates a virtual MIDI output port that allows LLMs to send MIDI messages to any compatible software or hardware. Built with Python using rtmidi and FastMCP, it provides tools for sending Note On/Off messages, Control Change commands, and precisely timed MIDI sequences with customizable parameters. The server is particularly valuable for AI music generation, controlling synthesizers, digital audio workstations, or any MIDI-compatible application, enabling LLMs to create musical patterns, control parameters, and generate complex sequences with accurate timing.
