The settings screen opens with B by default. Rebind it in Controls if another mod uses the same key.

  1. Press B to open the mixer.
  2. Set broad groups such as hostile, friendly, neutral, player, music, and ambience first.
  3. Open detailed controls only when a specific sound event or mob needs a different level.
  4. Trigger the real sound after editing; the result is combined with Minecraft’s standard master volume.
  5. Reset one category when it becomes difficult to identify which override changed a sound.

Start in a single-player test world or an approved server area. Change one option at a time, reproduce the same action, and keep the previous value in mind. This makes it much easier to identify whether a behavior comes from this mod, Minecraft, or another client mod.

When the screen is provided by Simple GUI API, use tabs to move between feature groups and profiles to keep separate value sets. Save or apply the current page before leaving it. A profile changes settings; it does not replace the installed JAR or create a separate Minecraft instance.

This mod does not override server rules. Features that automate input, reveal client-side information, or change how actions are presented may be restricted by a server. Test with the server owner’s rules in mind, and disable the feature when uncertain.

  • Confirm the feature’s toggle after joining a world.
  • Confirm that the active profile is the intended one.
  • Recheck key conflicts after adding another mod.
  • If behavior changes after an update, compare with default settings before reporting a bug.
