PHASELIGHT

Load a scene. Mod everything. Take the look. GPU shaders, 3D dioramas, screen capture and live media — mixed on a clip grid, a page per song, driven by audio, taken live and streamed anywhere.

MON 01 — The desk The Phaselight desk — a set list of pages across the top, ten columns of clips, and a staged-versus-live preview

Columns are looks, rows are layers, pages are songs — the whole desk in one view.

One instrument · every surface

A whole rig on a clip grid

Columns are looks, rows are layers, pages are songs. Six surfaces on one console — patch them together and drive the whole wall from the CUE deck.

CH 01

Six engines

100+ GPU shaders and your own GLSL, 3D dioramas, oscilloscopes, live media, a full text engine and instrument readouts — every one of them a clip you can stage and take.

CH 02

A page per song

Build the grid for one track, add a page, build the next. The pads never move: column 3 is column 3 on every page, so the same MIDI note plays your whole set.

CH 03

Cue / Take

Stage the next look on CUE, then commit with TAKE — instant, crossfaded or A/B. The floor never sees you work.

CH 04

The canvas

Drag a source anywhere on the output, crop it, skew it, corner-pin it onto a surface that is not a rectangle. Feather the edge so it melts into the scene under it.

CH 05

Flights

Place the same source differently in two columns and it travels between them when you take, instead of jumping. Nothing to set up — drag it where you want it and the flight is already armed.

CH 06

Live sources

A game, a browser, a second monitor, a camera — straight into a grid square, with every effect and transition a clip gets. Convert a clip to GPU format and run several video layers at once.

CH 07

The conductor

A segment is a list of steps: wait this long, then do that. Fire a column, take, hit, change page — each step waits from the one above it, so inserting one in the middle costs nothing.

CH 08

Mods

16 LFOs → unlimited targets

Plus audio envelopes, beats and full spectrum. Route-learn any parameter in a click and the whole rig breathes on its own.

CH 09

The timeline

Arrange a whole passage — clips, automation curves, text — then drop it on a grid square. Taking that square plays the arrangement out, once or on a loop.

See it move

Built like an instrument

Not a slideshow — a lighting desk. Every panel is live and hands-on. Click any monitor to zoom in.

MON 02Live output
A live Phaselight output frame — a cyan and magenta kaleidoscope with the words LAST LIGHT typing on in green

One clean master out

The finished frame the room sees — every engine, effect, layer and word composited and rendered at framerate, ready for the wall, a projector or the stream.

MON 03Readout
A Phaselight output frame built from instrument furniture — a tempo and position slate, a column of glyphs, and a corner-placed video panel

Instrument furniture

Counters, clocks, slates and meters that read the desk’s real numbers — not a decorative approximation. Place them anywhere on the frame beside your clips.

MON 04Pages
Three song pages cycling - the clips in every square change while the pad row above them stays put, with column three lit on every page

A page per song. The pads do not move.

Different clips, a different number of columns — the play buttons, MIDI notes and keyboard shortcuts stay exactly where they were. Column 3 is column 3 on every page, so the set you learned still plays.

MON 05Six bands
Six audio bands - sub, low, lo-mid, hi-mid, presence and air - moving on their own rhythms, with the struck band lighting up

Six bands, and each reports its hits

A kick and a bass note are no longer the same thing, and neither are a snare and a hat. A level meter cannot tell a held note from a strike — a hit can, and it is what makes a kick read on screen.

MON 06Flight deck
The Phaselight flight deck — a source map, a hop between two columns, and a grid of placement tiles

See the move before you make it

What a take will actually do: which layers fly and where from, which stay, which enter, which leave. Beside it, every source on the page and the columns that carry it.

MON 07Live Type
The Live Type deck — a message box, cue list, and walls of entrance and exit pads with envelope editors

Type it and it is on screen

Words appear as you type them. Choose how they arrive and how they leave — type on, cascade, decode, shatter, white-out — and keep a set list of lines ready to fire.

MON 08Sequencer
The Phaselight column sequencer with per-row lanes and BPM transport

Put it on a clock

A beat-quantized column sequencer with per-row lanes and BPM transport. Tap tempo, lock to MIDI clock or ride Ableton Link, and let the set run itself.

MON 09Mods rack
The modulation rack — 16 macros with an expanded LFO showing shape, rate and range controls

16 LFOs, unlimited targets

Every macro assignable to any number of parameters, plus audio envelopes and spectrum. Route-learn a control and it breathes on its own.

How a set flows

Three moves, endlessly

01 Load

Cue the next look

Pick engines, dial FX, arm a HITS gesture. It stays private on the CUE deck until you commit — the floor sees nothing.

02 Mod

Make it move

Bind 16 LFOs, audio envelopes and MIDI to any parameter. The look breathes with the music before you ever push it live.

03 Take

Commit on the beat

Hit TAKE to push it live — instant, crossfaded or A/B swap. The sequencer can fire it for you, quantized to tempo.

Get it out of the box

Made for stages & streams

Phaselight shows up as a webcam and streams full-framerate over the network — no capture-card gymnastics. Drop it straight into your broadcast.

Virtual camera

Phaselight appears as a webcam in OBS, Zoom and Discord — one-click install, no capture card.

Pro

NDI output

Full-framerate, GPU-scaled network video to any NDI-ready switcher or machine on your LAN.

Pro

OBS & window split

A clean full-screen output on a second display with a live confidence monitor — straight into OBS or the projector.

Core

Core · Pro · Packs

The instrument is free

Everything you build and play a set with is in Core, and Core is not a trial. Pro adds the ways a set leaves the machine — another app, another computer, a recording, a stream. Packs are a third thing: bought on their own, and they work in Core and Pro alike.

Pro is free during the beta. Every beta key unlocks all of it, on Windows and on the Mac, with no purchase while Phaselight is pre-1.0. Settings › License shows this same comparison marked for the machine you are on.
Packs are separate. A pack is bought on its own and runs in Core and Pro alike — holding Pro does not include it, and buying Pro does not unlock it. Three Schematic packs are on the shelf now; checkout opens shortly.
Phaselight 0.7.3 - The Setlist, over a spectrum of six bands snapping on the beat

Free to download

Run your first set tonight

The Core tier is free, and it is not a trial — the whole instrument, all of the content, and every way of playing it. A beta key unlocks the Pro outputs and is free during the beta. We hand keys to testers one at a time.

v0.7.3 — “The Setlist” · Windows (Pro) · macOS Core and, new, a first-look macOS Pro with NDI and Syphon (Apple Silicon) · both Mac builds unsigned — right-click → Open on first launch · every build from v0.6.2 onward auto-checks for updates and installs them in-app.

Updating starts your desk from defaults. Your media files and your licence key are untouched, but grids, pages, shows and settings are cleared. Screenshot anything you want back before you install.
