Redstone Automation

Redstone and Automation

Mixer can start a jukebox playlist from a barrel or shulker box. Playlist items are read from the container's inventory order and can mix custom discs with writable-book text-to-speech entries.

Setup

1. Place a jukebox.
2. Put a barrel or shulker box directly above it.
3. Place a redstone repeater adjacent to and pointing into the jukebox.
4. Fill the container with custom Mixer discs and/or writable books.

Trigger behavior

Mixer reacts when the repeater becomes unpowered. It applies a one-second cooldown per jukebox, scans the container, and starts a new playlist if at least one valid entry is found. Any existing Mixer player for that jukebox is reused; otherwise one is created.

Playlist entries

• A custom disc contributes its stored Mixer source.
• A WRITABLE_BOOK contributes all of its pages as one text-to-speech entry.
• Other items are ignored.

Entries remain in the same order as their inventory slots.

Example

For a station announcement, put a writable book in the first slot and a burned sound effect disc in the second. When the repeater loses power, Mixer reads the announcement and then plays the sound effect.

Text-to-speech uses an online Google Translate endpoint, so the server needs outbound network access and availability is not guaranteed. Avoid putting sensitive text in books used for TTS.

Redstone output command

The /mixer redstone command is unrelated to this playlist trigger. In Mixer 2.3.0 it stores experimental output-point metadata, but playback does not yet consume that data. See Commands.
