CDisc Music 1.7

1.6 shipped speaker groups with a caveat: per-speaker channel and volume only did anything on Plasmo Voice. That caveat is gone. Simple Voice Chat now honours both, and a jukebox carried on Simple Voice Chat no longer breaks up while you run.

The second headline is search you can pick from. A query that isn't a link lists what it found in the chat, and you click the track you meant instead of taking whatever came first.

Two things for server owners: API keys move out of config.yml into their own file, and CDisc gains permissions and limits on what a player can make your server fetch.

Simple Voice Chat catches up

Per-speaker channel and volume now work. Simple Voice Chat was handed audio that had already been encoded, so every output of a group received byte-identical sound — the settings saved to the block, showed up in the GUI, and had nothing to act on. Each output is now encoded separately, so a pair of speakers can split a stereo image the way it always could on Plasmo.

Stereo folds to mono there, because Simple Voice Chat has no stereo stream to offer — its encoder is single-channel throughout. Left and right stay genuinely different, which is what splitting an image across two speakers actually needs.

A carried jukebox stays clean. Carrying one used to make the music break up while moving: the audio came from a source sitting on your own ears, and at zero distance the direction from listener to source is undefined, so it swung on every step. The carrier now gets a channel with no position at all — steady in both ears — while everyone else keeps hearing it from where you're standing. The swap overlaps in both directions, so picking a jukebox up and putting it down have no gap and no click.

This costs one Opus encode per playing output where Simple Voice Chat previously had none. It is the price of telling two speakers apart. It also removes an old penalty: a global volume below 100 used to force a full re-encode of every track, and no longer does.

Search you can pick from

/cdisc create yt:daft punk one more time

A query that isn't a link now lists what it found in the chat — number, title, artist, length — and every line is clickable. Click one and it's written to the disc in your hand.

Ask for a specific number of results by putting it on the end:

/cdisc create yt:one more time:10

Five by default, ten at most. A trailing :something is only read as a count when it really is a number, so yt:nightcore: reloaded stays one query, and links aren't parsed for it at all.

The disc records the track's own address, not your query. A disc written from a search keeps playing the track you picked even if the same words return something else next year.

Three rules keep the list honest: it belongs to whoever searched, so someone else clicking it does nothing; choosing consumes it, so one search writes one disc; and it expires after three minutes rather than quietly writing a track you'd forgotten about.

Keys live in their own file

config.yml held Spotify secrets, Yandex tokens and VK credentials in among the ordinary settings — the one file you'd paste into an issue report or hand to somebody helping you debug.

Configuration is now four files:

File	Holds
config.yml	Plugin settings
sources.yml	Which sources are on, and their options
permissions.yml	Rights and limits
tokens.json	Every key and secret

Nothing to do on update. The split happens on first start: the new files are written, then the moved sections are removed, and the original is kept beside them as config-before-split.yml.bak. Nothing is deleted until the replacements are safely on disk.

tokens.json is the one file to keep out of screenshots and bug reports.

Permissions and limits

Every command now sits behind a node, registered with the server at startup so LuckPerms and friends can see them by name:

cdisc.create           cdisc.create.playlist   cdisc.clear
cdisc.player           cdisc.pair              cdisc.portable
cdisc.messages         cdisc.admin

The defaults match how CDisc behaved before it had permissions, so updating changes nothing until you change something.

Then there are limits, and they exist for a specific reason: /cdisc create makes your server fetch a URL that a player chose.

Setting	Default	What it does
create-cooldown-seconds	5	Wait between two creates by the same player
max-track-seconds	0	Longest track allowed on a disc; 0 is unlimited
allow-live	true	Whether live streams may go on a disc
allowed-hosts	empty	Fill it in and only these hosts are permitted
blocked-hosts	empty	Hosts refused outright

A leading www. is ignored and subdomains count, so youtube.com also covers music.youtube.com. Search queries aren't URLs and neither list touches them — they can only ever reach the source they name.

Refusals always say why, in chat. cdisc.admin ignores all of it.

Playback survives a restart

resume-playback: true

Jukeboxes pick up where they left off — same track, same second — instead of going silent until somebody re-triggers them.

Resuming waits for the chunk to load, so a jukebox in an empty corner of the map costs nothing until a player walks over. A jukebox that was paused stays paused, since resuming it would be starting music nobody asked for. Live streams come back at the live edge rather than a stale position.

Sound settings for a jukebox on its own

The channel, volume, name and particle settings introduced in 1.6 were reachable only through the speaker-group screen, which meant a single jukebox couldn't be turned down without pairing it to something first. Sound now opens the same screen from the player GUI on any jukebox.

The update checker actually tells you

Three separate reasons it stayed quiet, all fixed:

• It only checked at startup. A release published while your server was already up was invisible until the next restart. It now re-checks on a timer, every six hours by default (update-checker.interval-hours).
• It hid releases over their version list. A build that didn't name your exact Minecraft version was treated as not existing. Versions are now matched by family, so a server on 26.2.build.56 matches a release listing 26.x.
• Notices are warnings, so they stand out in a console instead of scrolling past among the info lines.

Documentation

CDisc has a documentation site: 19 pages in English and Russian, with search, per-page contents and a dark theme. Everything below the surface of this changelog is written up there properly.

Smaller things

• /cdisc create with a playlist link tells you how many tracks it left behind, and points at create-playlist.
• Source settings moved to sources.yml, so turning YouTube's fallback API on no longer means editing the same file as your speaker-group limits.
• A source with no key is skipped with a line in the console at startup, rather than registering itself and failing later.

Fixes

• An unconfigured Spotify registered itself anyway. The shipped placeholder was the literal text null, which every check treated as a real client ID — so the source came up with null as its credentials and failed on use instead of standing aside.

Compatibility

Minecraft 1.20 through 26.x, on Spigot and Paper.

Per-speaker channel and volume now work on both voice backends, which supersedes the note in 1.6 that they needed Plasmo Voice. The one difference left: a stereo setting folds to mono on Simple Voice Chat, since it has no stereo stream. Left, right and mono behave identically on both.
