Your lights,
on the beat.

PitchControl! listens to the music and plays your lights with it. Peaks fire the strobo, the room glows in between, and a moving mask spreads it all across your rig. Run it from the keyboard or a MIDI controller, send it over DMX or Art-Net.

For macOS (Apple Silicon) and Windows. Version 1.2.1, released 2026-10-09. What’s new

The General page of PitchControl: 16 macro faders, function buttons, scenes, a scene preview and the audio analysis.

01/How it works

  1. 01

    Audio in

    Your audio interface, a mixer feed or simply a microphone.

  2. 02

    Analysis

    32 frequency bands. An octave-weighted trigger finds the peaks.

  3. 03

    Strobo / idle

    Every peak fires the strobo. In between, the lights fade back to their idle colours.

  4. 04

    Mask

    A moving mask spreads the light across the room.

  5. 05

    Output

    DMX over USB, Art-Net or serial, 40 frames per second.

02/Mask presets

Four ways to move light through a room.

Every fixture has a place in the room, and the mask decides how bright each pixel is. Change the speed and shape from the faders, mirror it with symmetry, and switch presets with a smooth crossfade.

GradientA

A soft fade across the room, vertical or horizontal.

Back & ForthB

A wide band that sweeps from side to side.

Rotating LineC

A line turning around the centre of the rig.

NoiseD

Drifting clouds that jump to a new place on every peak.

03/Features

01

Strobo on the peaks

The audio analysis listens for peaks and fires the strobo with them. Decay, attack and reactivity are on faders, so you can go from a gentle glow to full-on flashes.

02

Two colour groups

Split the rig into groups A and B, each with its own hue and saturation. Let Auto Color pick from a palette, or swap the two with one button.

03

Eight scenes

Store all 16 macros in a scene and recall it with one key. Build the looks before the night, switch between them as the set evolves.

04

MIDI controller ready

Plug in a Novation Launch Control XL and play: faders, knobs and buttons are mapped out of the box. Other controllers are a small JSON file away.

05

DMX and Art-Net

Send to an Enttec DMX USB Pro, to Art-Net nodes on your network and to PitchPlease serial strips, all at once and across up to four universes.

06

Fixtures and rigs

Describe a fixture model once, channel by channel, then place as many as you need in a rig. Keep one rig per venue and load it in a second.

07

Control Desk

Every DMX channel as a fader. Take over any channel by hand, for a house light or a stubborn fixture, without leaving the show.

08

Fog on a timer

Run fog machines on a schedule, “every 60 seconds for 4”, or fire them by hand from the General page or your controller.

09

Made for the booth

A calm monochrome UI that dims down in a dark room. Everything works from the keyboard, and nothing needs an internet connection.

04/A look around

RigThe fixtures of one event: addresses, groups, placement in the room and per-fixture overrides.

The Rig page

Free, open source, ready for tonight.
