About this Mod

Discord

Notice:

This is my first mod. Do Not Expect Much.

As of now, the mod features are made to replace similar features in Recode as it has been discontinued. I am willing to add non-Diamondfire related features to expand this mod's functionality. You can come suggest some in my Discord server, or contribute to the project through GitHub.

Setup:

[!] This mod uses .nbs files obtained from Noteblock World.

  • Launch game with the mod.
  • Place .nbs files in NBS songs folder. (<Path to Profile>/NBSE/NBS Files/)
  • In Creative Mode, use /nbs gui to view songs.

Features:

  • /nbs load Imports songs using the format on Recode
  • /nbs load_custom Imports songs in a similar format, but the pitch values are raw key + fine pitch values multiplied by 1000
  • /nbs gui Opens an experimental GUI for importing songs
  • /nbs player Obtains a simple nbs player to play nbs songs

Planned Features

  • Gui shows more data about each song file
  • Config Menu
  • (Maybe) Client-Side player for previewing and reducing noteblock ping lag.

You Can Help:

  1. Clone the GitHub Repository.
  2. Make changes to help improve the mod.
  3. Create a Pull Request.

It has only been me and RedVortex working on this, but code suggestions can help further this mod. You can even add your own personal touches to existing parts. (e.g. UI adjustments.)

Frequently Asked Questions

NBS Extensions server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.

Is NBS Extensions compatible with fabric?

NBS Extensions officially supports fabric for Minecraft 1.21.11, 1.21.8, 1.21.4. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with NBS Extensions – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if NBS Extensions consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
