Composer - Music player that plays nbs files

This is a discussion topic for the Ore project, Composer. View the full project on Ore for downloads and more information.


This version has been updated to work with Sponge API v7. Original plugin post available at 🎼 Composer v2.0.0 -- Note block music importer and player [MC1.10.2+/API5+]

Composer is a full featured note block music importer and player. Import Note Block Studio files by placing them in the config/composer/tracks/ directory and the plugin will automatically load them on start.

Composer comes with a full music player built in as shown below. There are commands for each action you can perform within this menu as well as the text itself being clickable.

Composer Example


  • Per player music player for loaded tracks.
  • Play, pause, shuffle, skip, back actions.
  • Flexible API to allow developers to create compositions programmatically or import other file formats.


  • Place the composer-x.x.jar file in your mods/ folder.
  • Place your .nbs files in the config/composer/tracks/ directory.
  • Run the server.


As of v4.1.0 Composer support playlists. To use playlists enable the option in default.conf


Creating a playlist

  1. Under config/composer/playlists create a folder with the desired name.
  2. Place your .nbs files in the folder you created.
  3. Run the server.

Set a playlist

Run the /music playlist <playlist> command.

Setting a default playlist

Change the config option to the playlist name.

Hello, I’m a user of mcbbs. Could I reprint your sarhatabaot on the Forum

Sure, have fun :slight_smile:

hi this plugin plays the sound in all the map ? and can we put a sound ourselves and add the sound to the whole map with a command block ?

Bye and good night ^^

The plugin plays for each user independently.
You can add your own tracks by adding a .nbs file to the folder.

Hey! I was wondering if it’s possible to have an option to stop playing after the song finishes? instead of going to the next.

Thanks for this!
We want to use this for an RPG-style map but it plays all of the songs in a list rather than letting us specify which one to play by using the command.
Is there any chance we could get the ability to put the .nbs files in a sub-folder to specify the “playlist” built-in? Or at the very least, an option to put one song on loop rather than go down the entire list.

I’ll take a look :slight_smile:

Thanks! I really appreciate it.
