NBS Extensions
by mudkip989
NBS Extensions, a Fabric utility, lets players import songs from Diamondfire and other note block formats into a Minecraft world.
What it does
The mod reads NBS song files and imports them from Diamondfire, with support for the Recode format and for pitch values stored in the raw format. An experimental import screen is available for trying out new file handling, and a simple NBS player can play imported songs through note blocks.
Each song file can be inspected in a panel that lists its details before it is loaded, and a configuration menu lets players adjust options. The mod works only in the client, so single-player and multiplayer clients run it alone while the server does not need anything installed. It is open source under the GNU Lesser General Public License v3.0 only, and its source code and issue tracker are public. Files are published for Fabric only, with 1.21.11-0.1.5-fabric as the latest build.
