MCMidi
by Karasu Lab
Karasu Lab's MCMidi lets a Fabric client play MIDI files inside Minecraft, with a visualization control center for watching playback.
What it does
MCMidi reads standard .mid and .midi files and plays them through the client, with the sound coming from an .sf2 SoundFont. Players can load their own SoundFont files to change how the instruments sound. A dedicated Midi Control Center opens with several tabs, and each one shows a different view of playback: a real-time MIDI message log, BPM, the current playback position, the active MIDI nodes and a virtual piano roll that highlights the notes being played.
The mod is a client mod: only the client needs it, and servers run without it. It requires Cloth Config API, Fabric API and KarasunikiLib, and Mod Menu is optional for opening its settings from the mods list. Settings are adjusted in game through the configuration screen, which integrates with Mod Menu and Cloth Config. Files are published for Fabric only, for 1.21.1 and 1.21.7, with v2.1.2 for 1.21.7 as the latest. The code is open source under the MIT License.
