Note Block Radio

by ImplicitSaber

Note Block Radio lets note block songs travel beyond their own location, using transmitters, radios and minecarts that carry music across the world.

NeoForgeClient and serverMIT LicenseOpen source1.21.1

What it does

Music from nearby note blocks is picked up by transmitters and rebroadcast on a channel, so a song can be heard far from where it was played. Transmitters relay the signal through other radios, with a hop limit that caps how many relays a signal can pass through before it stops.

Minecarts with a transmitter can be activated by an activator rail to broadcast while they move, and a radio jammer can be used to disrupt a channel. Because the mod runs on NeoForge 1.21.1 only and needs the server as well as the players to run it, every participant needs the mod installed. The mod is open source under the MIT License.

Key features

  1. Song broadcasting

    Note block songs played near a transmitter are carried across the world and played back by receiving radios.

  2. Transmitter minecarts

    A minecart carrying a transmitter broadcasts music and can be switched on by an activator rail along a track.

  3. Radio jammer

    A jammer can transmit random note ticks when powered, which disrupts a channel and suits pranks.

  4. Adjustable ranges and channels

    Lossless and lossy ranges, a channel count and a relay hop limit can be set, with shift and right-click used to change a radio's channel.
