MineFantasia
Players who want to perform music with friends in Minecraft can use MineFantasia, a NeoForge instrument mod with a multiplayer ensemble system.
What it does
Holding an instrument in the main hand and right-clicking a placed instrument opens its performance interface. The interface has a Performance Area of 21 blocks around a middle block, each tied to a keyboard key from Q to U, A to J or Z to M, with the note name shown on it. The mod provides a wide variety of instruments, and the ensemble system lets several players play together in one world.
A Settings Area sits in the lower corners and holds five function buttons. Three stacked buttons on the lower left raise or lower the Current Center Octave Number, and two on the lower right raise or lower the Number of Raised Semitones. The arrow keys can be bound to these buttons. Center octave changes stop at the instrument's recorded highest and lowest octave, and semitone changes widen the note coverage one octave group at a time.
MineFantasia requires Geckolib. It runs on client and server, so the server and every player need it, and it is published for NeoForge only, for 1.21.5 – 26.2 across 8 release versions. The code is not open source; the mod is licensed under All rights reserved, and public links exist for the source code and the issue tracker.
