About this Mod

Note Block Radio

A mod that allows you to broadcast note block songs across your Minecraft world.

Features

Radio: Plays music transmitted by nearby transmitters.
Transmitter: Transmits music played by nearby note blocks when powered.
Minecart with Transmitter: Same thing as the transmitter, just in a minecart. Activate it with an activator rail. Great for long note block songs!
Radio Jammer: Used for trolling. Just transmits a random note every tick when powered.
Relay: Relays notes on a specific channel when powered.

Anything with a channel (transmitters, radios, etc.) can have its channel changed by shift+right-clicking it.

Config

Lossless Range: The range at which a transmission is received the same as it was sent. (Default 128)
Lossy Range: The range added onto the lossless range at which a transmission is received, but some notes may be lost. (Default 64)
Channel Count: The amount of channels available to select from. (Default 16)
Relay Hop Limit: The maximum amount of relays a signal can hop between to reach a radio. (Default 8)

Frequently Asked Questions

Note Block Radio server crashes on startup – what to do?

Most common cause: wrong neoforge 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 (1.21.1). You can switch loaders with one click in the panel.

Is Note Block Radio compatible with neoforge?

Note Block Radio officially supports neoforge for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Note Block Radio – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Note Block Radio 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.
