What Is RenderWave

RenderWave is a real-time, audio-reactive visuals engine for macOS. It runs a deep catalog of GPU shaders that react to your music, and it pushes them straight out to a projector, an LED wall, or the rest of your VJ rig.

You render nothing ahead of time and you keyframe nothing. The sound drives the picture live, while you perform.

Who it’s for

RenderWave is built for VJs, DJs, clubs, and festival production teams who need visuals that respond to a live set instead of looping on a fixed timeline. If you’re driving a screen behind a DJ, mapping projections onto a stage, or running an LED wall at a club night, RenderWave is the engine underneath.

Built on Metal

Most tools in this space still run on OpenGL, a graphics layer Apple deprecated and froze years ago. RenderWave runs on Metal, Apple’s current graphics framework, so it taps everything a modern Mac and Apple Silicon can give it. Put it on a faster Mac and you get a better show. The app scales up with your hardware instead of hitting the ceiling a decade-old framework set.

That foundation is what lets RenderWave hold high frame rates at high resolution and stay locked to the beat, even when a scene is doing a lot of work on screen.

What it does

Reacts to audio. Feed it a signal and the visuals move with bass, hits, and the overall energy of the track. You animate nothing. See How audio reactivity works.
Stays on tempo. RenderWave detects BPM from the music on its own, or you sync it to Ableton Link, tap it in by hand, or set it yourself. See BPM and tap tempo.
Takes MIDI control. Map a controller and drive scenes from hardware. Launchpad and APC pads light up with live feedback. See MIDI controllers.
Outputs a clean feed. Go fullscreen on any display, or send a Syphon feed into Resolume, MadMapper, or OBS. See Syphon and mapping.

Two views: play and build

RenderWave has two views, and you switch between them from the buttons in the top bar.

Performance view is the live surface, and the app opens here. A grid of scene cells sits over a fullscreen preview, and AUTOPILOT can cycle through them on its own. Tap a cell and the whole visual switches at once: shader, parameters, and effects together. You play finished looks here rather than building them.

Creator view is the workshop. The preview shrinks into a framed window and a full parameter panel opens: sliders, the step sequencer, audio routing, and effects. Here you dial a look in and save it. Each look you save shows up on the Performance grid as a new cell.

Build in Creator ahead of the show, then play in Performance when you’re live.
