About Pure Data (aka Pd)

Pure Data (or just Pd) is an open source visual programming language for multimedia. Its main distribution (aka Pd Vanilla) is developed by Miller Puckette. Pd-L2ork/Purr-Data is an alternative distribution (originally based on the now unmaintained, dead and deprecated Pd-Extended project), with a revamped GUI and many included external libraries.

What's New? As of Pd 0.47-0, the Deken library manager is included for easy access to community-developed external libraries that expand the capabilities of Pd such as Cyclone, zexy, and the computer graphics library Gem. For more details on new developments, see the Release notes.

Download Pd-L2ork 2.x (Purr Data)

What's New? Pd-L2ork has a new cross-platform 2.x version nicknamed Purr Data. Pd-L2ork 1.x is still available as well (Linux only), whereas Purr Data is available for Linux/Mac/Windows. More details in the linked download pages.

More about Pure Data

Pure Data is an open source visual programming environment that runs on anything from personal computers to embedded devices (ie Raspberry Pi) and smartphones (via libpd, DroidParty (Android), and PdParty (iOS). It is a major branch of the family of patcher programming languages known as Max (Max/FTS, ISPW Max, Max/MSP, etc), originally developed by Miller Puckette at IRCAM.

Pd enables musicians, visual artists, performers, researchers, and developers to create software graphically without writing lines of code. Pd can be used to process and generate sound, video, 2D/3D graphics, and interface sensors, input devices, and MIDI. Pd can easily work over local and remote networks to integrate wearable technology, motor systems, lighting rigs, and other equipment. It is suitable for learning basic multimedia processing and visual programming methods as well as for realizing complex systems for large-scale projects.

Algorithmic functions are represented in Pd by visual boxes called objects placed within a patching window called a canvas. Data flow between objects are achieved through visual connections called patch cords. Each object performs a specific task, which can vary in complexity from very low-level mathematical operations to complicated audio or video functions such as reverberation, FFT transformations, or video decoding. Objects include core Pd vanilla objects, external objects or externals (Pd objects compiled from C or C++), and abstractions (Pd patches loaded as objects).
