Notica
by LCLPYT
Notica lets a Minecraft world play Note Block Studio songs, reading the .nbs file format and sounding notes in-game.
What it does
Notica reads songs saved in the .nbs format used by Open Note Block Studio and plays them in-game. Its song playback extends the note range beyond the vanilla octave limits, so compositions made in the studio can sound close to how they were arranged. Songs are sent to clients as packed chunks, which means far fewer packets than sending each note separately.
Playback runs in one of two variants. The individual mode sends each note through Minecraft's own sound system, where a shared pool of 256 simultaneous sounds is used by the game too, so songs with many notes at once can have notes dropped and other game sounds cut off. The streamed mode mixes the whole song into one audio stream, handles dense songs without interfering with other sounds, and supports spatial or equal power stereo mixing. Clients with Notica installed play streamed songs directly through the OpenAL audio engine. The server must run the mod, while players may add it for streamed playback, and it works with vanilla clients on singleplayer and multiplayer servers.
Key features
Note block song playback
Play .nbs songs made in Open Note Block Studio, with note octaves extended beyond the vanilla range.
Packed song transfer
Songs are packed into chunks before they reach players, so the server sends fewer packets.
Two playback variants
Individual playback sends notes through the sound system, while streamed playback mixes the song into one stream.
Looping and stopping
A song can loop indefinitely, and the music stop command ends it in-game.

What the author says
However, if a player has the mod installed, the song notes are packed into chunks and sent in larger, but way less packets. This process is similar to video buffering. Clients with Notica installed do not have these limitations, as notes are played directly via OpenAL, the audio engine used by Minecraft: Java…
