NINJIX Master Mixer is a 24-channel mixing console for Unreal Engine, written in C++. Mix your game like a studio, inside the editor and for real in your packaged game.

Compatible with Unreal Engine 5.2, 5.3, 5.4, 5.5, 5.6, 5.7 and 5.8 (Windows). Built and tested on every one of these versions.

- 24-channel console + MASTER: faders in real dB, mute, solo and meters on every strip; the MASTER bus is your game's final output. Press PLAY on the mixer to hear your mix in the editor, no Play in the toolbar needed. Channel sounds, light colours and two console skins are remembered per project.

- 31-band equalizer on every channel: built-in presets or drag the bands to shape your own curve, heard instantly. A live frequency screen in three looks (NEON, LED, MIRROR) with your own colours. Your EQ settings save themselves and the game reopens with them.

- Fader automation: all 24 faders, the master and the mutes, with OFF, READ, TOUCH, LATCH and WRITE modes like a hardware desk. Record your moves while the music plays or draw them in the lanes window. Every recorded pass and every edit can be undone (Ctrl+Z). Play the automation back in your game with Blueprint nodes. A demo clip is included to learn from.

- NJX Media Player: play your own video files in the editor with their sound going through a mixer channel (its EQ, fader and the master apply). In your game: create a video player in Blueprints, show it full screen or on your own UI or material, and route its sound to any channel. No videos are included.

- NJX Music Visualizer 3D: drop it in a level and glowing bars dance to the master or to one channel (ring, line or mirrored wall), with peak caps, a Niagara burst on every bass hit and an OnBeat event for your own effects. Uses engine assets only.

- Export your mix: save a channel's sound WITH its EQ and fader as a new file, into your own mix library outside the project, ready for any project.

- Blueprint nodes: Play NJX Sound 2D (with a channel dropdown), Spawn NJX Sound 2D, Play Sound NJX at Location, Play / Stop Mix Automation, Create NJX Video Player, Set Channel Volume / Mute / Solo / EQ preset and more.

- Works with your own Claude Code (optional, Follow the Leader): ready to use with your own Claude Code and your Claude models, like Claude Opus. Ask it to read your mix, find the loudest channel, set a fader, shape an EQ or write fader automation. It runs on your computer only and is off until you turn it on; changes need your OK and every change can be undone. Requires your own Claude Code installation and Anthropic account. NINJIX and RXINC are not affiliated with or endorsed by Anthropic. Claude is a trademark of Anthropic.

- NJX Wave Splicer (included): waveform and spectrogram editor that cuts sounds into slices with zero-crossing snap, up to 3 windows, sessions and a Sequencer timeline; export slices as new sounds.

Includes full guides in the plugin's Docs folder (Markdown): the Master Mixer guide and the Wave Splicer guide. The mixer guide is also online as a PDF.
