MID PLAYER

by mcjava20

Mid Player lets the Minecraft client play standard MIDI (.mid) files without launching a separate music program alongside the game.

NeoForgeClient-side onlyMIT LicenseOpen source1.21.1

What it does

Once the required files are in place, the client can play .mid files directly inside Minecraft, so no external player has to be open during a session. The mod works only on the client, so servers do not need it and players joining a server do not need to add anything. Builds target NeoForge for 1.21.1 only, with version 1.0.0 published on 2026-08-18 as the first and latest file.

The setup is not install-and-go. The mod depends on a sound bank: FluidR3 GM.sf2 has to be placed inside the midplayer pack folder that lives in the .minecraft directory, and that folder has to be placed inside the version folder for the game build. If the version folder has not been created yet, it must be made first, since files placed outside it are not picked up. The mod is released under the MIT License and its source code is open source.

Key features

  1. Standard MIDI playback

    Standard .mid files can be played by the client itself, without running a separate application at the same time.

  2. Bundled sound bank setup

    The midplayer pack folder holds the FluidR3 GM.sf2 sound bank, which the playback relies on.

  3. Per-build pack folder

    Files are kept in the pack folder inside the version folder of .minecraft, so each game build reads its own copy.

Questions

Does Mid Player need to be installed on the server?

No. It is installed on the player's side alone, so servers need nothing.

Why does playback not start after installing the mod?

The mod needs the FluidR3 GM.sf2 sound bank inside the midplayer pack folder, placed in the version folder for the game build. Without the sound bank and the correct folder structure, playback is not set up.

Which loader and game version does Mid Player support?

It supports NeoForge only, for Minecraft 1.21.1. No other loader or game version is listed for the mod.

What the author says

The mod successfully solved the problem of Minecraft not being able to play MID files, but this mod isn't just install-and-go. Actually, you need to put the files from and into the midplayer_pack folder in your version folder (if it hasn't been created) (you need version isolation, otherwise put it outside the…
