OneMoreAudioController

The mod lets a player add audio controllers that are not part of the vanilla set. Each controller is a slider on the Music Sounds screen that sets the volume of only the sounds assigned to it, leaving Master, Players and the other vanilla controls untouched. Which sounds belong to which controller is decided in data files, so the controllers and their order can be changed without writing code.

Two JSON files, controllers.json and orders.json, define what controllers exist, the order they appear in and which sounds each one affects. Anyone building a modpack or resource pack can edit them. Assigning sounds to controllers in code is handled by the OneMoreAudioControllerApi Java API, which does not read from JSON, and the mod ships with no dependencies beyond Forge. Changes apply without restarting the game, and both files reload each time the Music Sounds screen is opened, including from the Mods menu's Config button, which works like the one in Catalogue.

The code is released under All rights reserved and is not open source, though its source code is publicly available. Usage details for the API are listed on the project's GitHub page. The mod is published for Forge only, for Minecraft 1.20.1, and the latest file is 1.2, dated 2026-08-01.
