Instrument++ Reborn

by MarzMan232

Instrument++ Reborn adds custom noteblock instruments to Minecraft, and it is a NeoForge rebirth of the original Instrument++ mod.

NeoForgeClient and serverMIT LicenseOpen source1.21.1

What it does

Noteblocks gain a set of extra instruments through the mod, sixteen in all, and the mod also provides an API that other developers can use to register their own noteblock instruments. Custom instruments work on Sable Sublevels, so they keep playing on moving structures built with Sable Aeronautics.

The project is a fork of the original Instrument++ by Viola-Siemens, aimed at porting the mod to other Minecraft versions and fixing bugs in the original, which may also restore compatibility with certain other mods. Work listed for later includes a JEI fix, ports to other 1.21.x versions, versions for 26.x, a backport to earlier releases, and a Fabric port. New features are planned for later releases.

Installation needs NeoForge. Files exist for 1.21.1 only. The mod is released under the MIT License and is open source, and its source code and issue tracker are public. Because the environment is client and server, both the server and every player need the mod.
