- Pixelblaze - an advanced LED pattern development engine and controller. It makes it fast and fun to write new patterns with its web-based live editor and highly optimized expression engine. Pixelblaze can store hundreds of patterns and lets you write new ones by entering mathematical expressions or code that update live as you type. No more time consuming compile, upload, test cycles! Pixelblaze is optimized for speed and can produce hundreds of frames per second for extremely smooth animations. Pixelblaze was designed for APA102 LEDs (aka DotStar). These LEDs are state-of-the-art and provide rock solid updates, faster refresh cycles, and the possibility of a dynamic range well beyond 0-255. Pixelblaze also supports WS2812 (aka NeoPixel) LEDs and WS2801, as well as the compatible clones such as SK9822, and SK6812.

- https://en.wikipedia.org/wiki/0-10_V_lighting_control - one of the earliest and simplest electronic lighting control signaling systems; simply put, the control signal is a DC voltage that varies between zero and ten volts. In production lighting this system was replaced by analog multiplexed systems such as D54 and AMX192, which themselves have been almost completely replaced by DMX512. For dimmable fluorescent lamps (where it operates instead at 1-10 V, where 1 V is minimum and 0 V is off) the system is being replaced by DSI, which itself is in the process of being replaced by DALI.
- https://en.wikipedia.org/wiki/DMX512 - standard for digital communication networks that are commonly used to control stage lighting and effects. It was originally intended as a standardized method for controlling light dimmers, which, prior to DMX512, had employed various incompatible proprietary protocols. It soon became the primary method for linking controllers (such as a lighting console) to dimmers and special effects devices such as fog machines and intelligent lights. DMX has also expanded to uses in non-theatrical interior and architectural lighting, at scales ranging from strings of Christmas lights to electronic billboards. The use of DMX can now be used to control almost anything, reflecting its popularity in theatres and venues.

This site acts as a resource for anyone looking for information about DMX software and the associated control systems, as well as a variety of Open Source and free lighting software.
- https://en.wikipedia.org/wiki/RDM_(lighting) - Remote Device Management or RDM is a protocol enhancement to USITT DMX512 that allows bi-directional communication between a lighting or system controller and attached RDM compliant devices over a standard DMX line. This protocol will allow configuration, status monitoring, and management of these devices in such a way that does not disturb the normal operation of standard DMX512 devices that do not recognize the RDM protocol.
- https://en.wikipedia.org/wiki/Art-Net - a protocol for transmitting the lighting control protocol DMX512-A (with RDM) over the User Datagram Protocol of the Internet Protocol suite. The protocol was developed by Wayne Howell and his company, Artistic Licence Engineering (UK) Ltd, is open for implementation with attribution but without charge, and made available as a software development kit for convenience. It is typically implemented as lighting-control nodes in embedded controllers, driven from a lighting desk or similar software operating as a server. Art-Net compatible products are made available by dozens of companies.
- https://en.wikipedia.org/wiki/Digital_Signal_Interface - a protocol for the controlling of lighting in buildings (initially electrical ballasts). It was created in 1991 by Austrian company Tridonic and is based on Manchester-coded 8-bit protocol, data rate of 1200 baud, 1 start bit, 8 data bits (dimming value), 4 stop bits, and is the basis of the more sophisticated protocol Digital Addressable Lighting Interface (DALI).
- https://en.wikipedia.org/wiki/Digital_Addressable_Lighting_Interface - IEC 60929 and IEC 62386 are technical standards for network-based systems that control lighting in building automation. They were established as a successor for 0-10 V lighting control systems, and as an open standard alternative to Digital Signal Interface (DSI), on which it is based.
- Open Lighting Architecture (OLA) - a framework for lighting control information. It supports a range of protocols and over a dozen USB devices. It can run as a standalone service, which is useful for converting signals between protocols, or alternatively using the OLA API, it can be used as the backend for lighting control software. OLA runs on many different platforms including ARM, which makes it a perfect fit for low cost Ethernet to DMX gateways.

D:Light users can also avail of a standard command-line syntax.
- CHA/V - (CHEAP, HACKY, A/V) is an #open-source, #DIY, #audiovisual, #A/V, #video synthesizer, that has inexplicably been built by civilians around the world, as well as in international workshops and fancy art schools. (ok, got all my impressive-sounding words and hashtags in there, now we can begin communicating like humans). If you are new to video synths, fasten your seatbelt. You just opened up a huge can of wormholes.
- Synkie - a modular open source analog video processor, developed byMichael Egger, Flo Kaufmann and Max Egger. Like the venerable modular Moog synthesizer it lets you toy around with the signal using patch cables – but this time not producing sound but images. It is an instrument for video, a playground, a platform to explore new ways to transform a video signal. Synkie is still in development, we constantly develop new modules – and even the base specifications may still change over time. But right now there’s already enough stuff to have fun playing around and the instrument has already a complexity that gets hard to control…
- QLC+ by Massimo Callegari - a free and cross-platform software to control DMX or analog lighting systems like moving heads, dimmers, scanners etc.
This project is a fork of the great QLC project written by Heikki Junnila that aims to continue the QLC development and to introduce new features. The primary goal is to bring QLC+ at the level of other lighting control commercial softwares. QLC+ runs on Linux, Windows (XP+), macOS (10.7+) and the Raspberry Pi.
- Quantum VJ HD - a simple glitch-style audio visualizer (video generator). It can receive sound from the microphone or from the Line-in port (depends on the system settings). Sound will be converted to the graphic elements byte by byte. The final video can be mixed with the camera stream in real time. Based on the algorithms from the Quantum VJ (pendant). This app is free for all systems, except the Android and iOS.
- https://github.com/revast/dvj - A vj and Dj program by interim_descriptor. original release statement from 2009: "For a decade, I've been working on a DJ + VJ program called "dvj". In short, it gives the user a pair of video-linked turntables: Scratching with a MIDI controller scratches both the audio and video. This is the only program I use at my shows, and I'm quite happy with it."
