General

  • Pure Data (aka Pd) is an open source visual programming language. Pd enables musicians, visual artists, performers, researchers, and developers to create software graphically, without writing lines of code. Pd is 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. Pd is suitable for learning basic multimedia processing and visual programming methods as well as for realizing complex systems for large-scale projects.



Builds / implementations

pd

pd-extended

  • pd-extended has two main goals: provide a standard collection of libraries and distribute core modifications to Pd itself. Providing a package that includes many libraries not only means that they are easy to use, but also acts as a standard platform so that patches can be used across many computers easily. Pd-extended includes most of the libraries from the pure-data source code repository. It is generally the most complete assembly of all available libraries, extensions, and documentation.

not updated anymore, uses pd 0.43.4

pd-l2Ork

Linux Laptop Orchestra's pd-l2ork offers a slew of usability improvements and a large collection of 3rd party externals. This is likely the last major release before transitioning from tkpath onto node-webkit renderer. Please note pd-l2ork continues to be developed on a regular basis with over dozen minor releases since the last major release posted on puredata.info. Once again, tons of new updates, most notably expanded K12 module including Raspberry PI GPIO with comprehensive PWM and I2S support, bunch of small improvements and bug fixes (e.g. comments with endlines or iemgui labels with spaces), documentation improvements, and comprehensive Wiimote support using a custom libcwiid fork (included in the source, also available as a separately downloadable tarball) offering interleaved motion plus and expansion data retrieval, as well as recently added support for the new version of MotionPlus Inside wiimotes. Pd-L2Ork is a monolithic release that includes most of the pd-extended libraries in one convenient package with a growing number of externals having their own standardized help files. In this latest version, pd-l2ork can be installed alongside other pd variants and there are no lingering conflicts between various packages.

libpd

  • libpd is Pure Data. It is not a fork of Pure Data, not a different flavor of Pure Data. It is simply a way of using Pd in a new way that can be more convenient and allows compatibility with mobile app development, game development, embedding into sophisticated 3D visualization tools, and lots of other applications. As such, it adds to Pd, without taking away anything from Pd Vanilla’s DSP core.

ZenGarden

  • https://github.com/mhroth/ZenGarden - a runtime for the Pure Data (Pd) audio programming language. It is implemented as an extensible audio library allowing full control over signal processing, message passing, and graph manipulation. ZenGarden does not have a GUI, but easily allows one to be built on top of it.

PdDroidParty

  • PdDroidParty - Run your Pure Data patches on Android with native GUIs emulated.

WebPD

  • https://github.com/sebpiq/WebPd - a 100% JavaScript Pure Data runtime using Web Audio API to play audio in the browser. It aims at allowing a subset of Pure Data programming language to run in the browser without plugins and with best possible performance. WebPd should be supported by all browsers supporting Web Audio API.


purr-data

  • purr-data - Pure Data Visual Programming Environment ported to an HTML5 GUI

pd-nw

Camomile

  • https://github.com/pierreguillot/Camomile - a plugin with Pure Data embedded that offers to load and to control patches inside a digital audio workstation. The plugin is available as VST, VST3 and Audio Unit for Windows, Linux and MacOS.

MobMuPlat

  • MobMuPlat - a standalone iOS+Android app which hosts and loads from a list of available works. Creating your own work consists of two parts. First, creating a graphical user interface (GUI) with the MobMuPlat Editor (OSX and Java versions available); second, creating the audio engine using the graphical programming language Pure Data (PD). With both of these applications open, and data sent between the two, you can simulate the app behavior on your laptop/desktop. Once development is complete, just drag the two saved files into the "Documents" folder of iTunes, and they are uploaded to your iOS device and can be opened in the MobMuPlat app. (For android, get the files onto your device storage folder anyway you like, then open them in the MobMuPlat app).

hvcc

empd

  • empd - Pure-data compiled with Emscripten. Run Pd patches (without GUI) in a web browser. There is also WebPd with a limited subset of Pd functionality. empd is full Pd vanilla -nogui. Emscripten compiles C to HTML, Javascript and Web Assembly. A small stub program written in C interfaces between libpd and SDL2 Audio API (which is implemented by Emscripten). The patch files are preloaded into Emscripten's virtual filesystem at compile time.

Data structures

"Pd is designed to offer an extremely unstructured environment for describing data structures and their graphical appearance. The underlying idea is to allow the user to display any kind of data he or she wants to, associating it in any way with the display. To accomplish this Pd introduces a graphical data structure, somewhat like a data structure out of the C programming language, but with a facility for attaching shapes and colors to the data, so that the user can visualize and/or edit it. The data itself can be edited from scratch or can be imported from files, generated algorithmically, or derived from analyses of incoming sounds or other data streams."





  • PDcontainer - C++ STL (Standard Template Library) Containers in PD



Serialization


Patches


  • mbass - a feature rich analogue modeled bass drum synthesizer, with exponential envelopes, distortion, a trigger synced LFO, and many other cool features.

https://github.com/noizhardware/Pure-bAo - PureData Abstractions Library



  • https://github.com/gusano/extended-vanilla - Some pd-extended objects ported as pure-data vanilla abstractions. pd-extended users often tend to become lazy :mouse: and use some externals which only come with pd-extended although the same result can often be achieved with pure-data (vanilla). I find that trying to work with pure-data (vanilla) as much as possible is good for the following reasons: that's an amazing brain exercise (think puzzles); that's a great teaching base to show to beginners and intermediate users; 100% compatible with standard pure-data out-of-the-box


  • Metastudio 5 - Over the past 12 years I have been generating a set of abstractions for working with Pd-Extended. This has gradually exploded into a large library of objects for synthesis, audio processing, sequencing, live sampling and audio file manipulation.


  • https://github.com/aalex/pdmtl - Pure Data Montreal Abstractions. The main concept in this library of abstractions is to group the abstractions by their function rather than their author. It is an answer to the disorder in the large amount of abstractions and externals for Pure Data. The library also proposes methods for unifying the usage of GOP (graph-on-parent), audio samples and much more. It is also intended as a wrapper for very useful externals for Pd that are often named badly or not well know.



  • https://github.com/brbrofsvl/array-abs - Array Abstraction Library for Pure Data (version >= 0.45)This collection of abstractions uses the new [array] objects in Pd version 0.45 and higher to create flexible, familiar, and reliable tools for manipulating arrays, in the vein of the list-abs library. A list of all current abstractions may be found in the file 000-array-abstraction-library.pd in the main directory.


  • https://github.com/ericlyon/pd-fftease - a collection of objects designed to facilitate spectral sound processing in Max. The collection was designed by Eric Lyon and Christopher Penrose in 1999, and has been maintained by Eric Lyon since 2003.


  • polywavesynth - a ready-to-use, CPU-cycle-stingy, OSC-addressable polyphonic "wave" synthesizer for Pd. The tag "wave" is used for want of a better (short) descriptor for the somewhat unusual mix of synthesis technologies employed, which is table-driven subtractive synthesis with a dash of FM. polywavesynth is a front end/UI which directs control messages to multiple instances of polywavevoice~, which is the synthesizer engine for each voice. It is theoretically possible to use a polywavevoice~ on its own, but it would just be a mono synth with a somewhat cumbersome method of parameter addressing. Its real power comes from being invoked and managed by Frank Barknecht's polypoly object (see below), as is done by polywavesynth.
  • polygrainsynth - a ready-to-use, OSC-addressable polyphonic granular synthesizer for Pd. Its engine is a modified version of [a_grain], an abstraction by Jamie Bullock. polygrainsynth is the younger sibling of polywavesynth. Its implementation of polyphony, using Frank Barknecht's polypoly object, is identical to that of polywavesynth.
  • granita - Minimalist granular synthesis for tables (aka arrays) - files or live loop recording. Granita is Pd Vanilla compatible
  • Swirler - an interactive, spatialized soundscape that is generated purely from the noises in the room.
  • Beatmangle - using a single audio loop, produces persistently changing audio by randomly moving the play head and loop settings. This is a particularly effective technique for generating Squarepusher style beats.


  • Particlechamber is a 32-voice asynchronous granular synthesizer for real-time transformation of a soundfile. It is loosely based on the famous Travelizer instrument from Reaktor 3, however I think it’s much better because it is FREE!


  • http://grrrr.org/research/software/upp
    • https://github.com/grrrr/upp Universal Polyphonic Player (short UPP) is an infrastructure for all kinds of polyphonic events – be it note-like events, other generated sounds or short grains in granular synthesis. The strengths of the system are a modular, easily extendible design, almost unlimited polyphony, ease of control, DSP load scaling and sample-accurate timing.








  • mxdublin is a generic programmable event sequencer written for pure-data or Max/MSP. The generic term is used since it is can sequence both: atoms or midi data via atoms.





Control




Tempo

Synth


  • synthPond - a relaxing spatial sequencer and audio toy by conceptual new media artist Zach Gage. Unlike a normal sequencer where you place notes on a grid and a moving playhead plays them, in synthPond you place nodes in a field (pond). There are two major types of nodes. Circular nodes release waves at certain intervals. Hard-edged nodes release waves when waves hit them. Moving these nodes about allows you to create complex and relaxing melodies. Additionally, because all the nodes are spatially organized, the audio generated can also be placed in a 3D space, occurring around the listener coming from the relative positions of each node.

Arpeggiation

Generative



  • https://github.com/GiantSteps/house-harmonic-filler - The House Harmonic Filler is a temptative model for chord variation that could be used in contexts of live electronic music performance. Based on corpus analysis of MIDI files, it provides a framework for variation and extension of chord progressions, generating MIDI data that is sent out to your preferred device or DAW.


Sequencing

  • context - a Pure Data sequencer which re-imagines musical compositions as networks. Instead of filling a timeline with information or drawing dots on a page, Context invites you to make music by creating and playing with a Context network. A Context network consists of multiple Context objects connected together so that they interact. The user programs musical content and instructions into each Context object, which can be customized and expanded indefinitely. This makes Context one of the most powerful platforms for making music you can imagine.

  • https://puredata.info/downloads/libdir - a Pure Data loader which supports the libdir library format. The libdir library format aims to be a common library format for Pd which works with objects written in any language, including Pd. This library format was designed to be easy to create, install, and use. It should work when installed into the global path (i.e. pd/extra) or when copied locally into a project folder. It should work with objects written in any supported language (i.e. binaries, .pd, and the various loaders like pdlua and tclpd).

Pd is split into two processes: pd (the core) and pd-gui. A simple pd external just runs in the core. A simple Tcl externals still runs in the core, because tclpd creates a Tcl interpreter for that.

Instead, pd-gui has its own Tcl interpreter. In order to to GUI things (i.e. draw on the canvas, or react to mouse events), the core process needs to communicate with the pd-gui process (generally sending Tk commands, or calling procedures defined in the pd-gui interp. This is done with the sys_gui() function, if using the plain API. 


TCL_LIBRARY="/usr/lib/pd-l2ork/tcl/library" TK_LIBRARY="/usr/lib/pd-l2ork/tk/library"

TCL_LIBRARY looks for the directory with init.tcl. On Arch, this is /usr/lib/tcl8.[5,6]

  • https://github.com/pure-data/deken Deken is a new Pd plug-in for package management. It makes finding and installing externals a breeze on any platform Pd runs on. Since maintenance of Pd-extended has been stuck for quite a while, netpd development will stop supporting it and instead make sure that the necessary externals are available through deken.



  • Cyclone is a library of PureData classes, bringing some level of compatibility between Max/MSP and Pd environments. Although being itself in the early stage of development, it is meant to eventually become part of a much larger project, aiming at unification and standardization of computer musician's tools.


  • https://github.com/enrike/ehu-abstractions - EHU is a set of abstractions for PureData real-time graphical programming environment. EHU aims to allow for rapid prototyping of interactive systems. Most abstractions in EHU encapsulate the GUI widgets to control them minimising the job of creation of widgets and connections. EHU covers playing video files, controlling video cameras, displaying pictures, playing samples, audio effects, DMX controls, and some general utilities. Note that it relies on several externals included in pd-extended.
  • https://github.com/porres/pd-else - a big library that provides a cohesive system for computer music, it also serves as a basis for an Live Electronics Tutorial by the same author: Alexandre Torres Porres. This tutorial is also found as part of the download of the ELSE library.


  • readanysf~, a puredata external for reading multiple file formats.


  • https://github.com/kronihias/smpte- - Pure Data/Max (flext) external for generating or decoding ltc audio timecode. Allows to sync to a DAW or sync two Pd instances via audio connection - and therefore having the same latency as your audio stream. using libltc library by Robin Gareus. based on Max object by Mattijs Kneppers



  • Slice//Jockey for Pure Data. Imagine a DJ set, and instead of turntables or cd players or iPods, it has two recorders. Real-time-beat-slicing recorders. Sound from your microphone is analysed, and sliced into coherent fragments which are engaged in playback rightaway. Slice//Jockey is a crossover of music game and live performance tool. Slice//Jockey is one fruit of slicerec~ and sliceplay~, Pure Data externals designed for real-time beat slicing.


  • oscbank~ - for additive synthesis. This is a plugin (aka 'external') for Miller Pucketter's PureData ("pd"). It was written in order to synthesize sinusoidal models that consist of hundreds of partial sinewave components. The external takes three control-rate parameters for each partial: index(unique), frequency, and amplitude. It stores this information in a bank and synthesizes each partial by interpolating between frames.


  • pmpd is a collection of object for with pd. These objects provide real-time simulations, specially physical behaviors. pmpd can be used to create natural dynamic systems, like a bouncing ball, string movement, Brownian movement, chaos, fluid dynamics, sand, gravitation, and more. It can also be used to create displacements thus allowing a completely dynamic approach of pd computing.


  • http://grrrr.org/research/software/py/ py/pyext – This object library provides full integration of the Python scripting language into the Pure Data and Max real-time systems. The library contains two main external objects: py loads Python modules and allows to execute functions therein. pyext uses Python classes to represent full-featured message objects. Multithreading (‘detaching’) is supported for background operation.





  • Slice//Jockey is a crossover of music game and live performance tool. Imagine a DJ set, and instead of turntables or cd players or iPods, it has two recorders. Real-time-beat-slicing recorders. Sound from your microphone is analysed, and sliced into coherent fragments which are engaged in playback rightaway.
  • Recursion Looper is a PD(Pure Data) patch designed for live music performance. -8 loop tracks -Track effects: reverb, bitcrush, filter -Master effects: filter, 3 band EQ -customizable MIDI control of volume, pan, effects, record and play, etc.


  • moocow:pd - patches and externals for Miller Puckette's Pd, constructed, written, hacked, munged, frobbed, and/or tweaked by moocow.






Instruments


  • Egregore source - an adaptation of the software used by chdh for the performance egregore in 2011-2014. It is based on five different audiovisual instruments made of chaotic and physical modeling algorithms that you can directly control. They have been remotely controlled live by chdh the 27th may 2015. It is available as a software to download or as a usb stick.


DSP

  • Freeverb - a simple implementation of the standard Schroeder/Moorer reverb model. It uses 8 comb filters on both the left and right channels. Note that this version of Freeverb doesn't contain predelay, or any EQ. It is implemented as a Pd object, so it can easily be inserted into a Pd patch.
  • FFTease, a set of live spectral sound processors for Max/MSP and Pd. Caveat: these objects are CPU intensive. A few of these objects in a patch could push your computer to its limits. Be very careful with playback volume as some of the objects produce dramatically different (lower or higher) overall levels.



  • nSLAM - an open-source audio suite for multi-channel audio application development, developed by the SAT Audio Group. It is written for the PD (Pure Data, by M. Puckette) environment and includes a library of low-level DSP objects called “xjjimmies” (also running in Max/MSP), online help, and example applications for multi-channel audio streaming and immersive audio, among others. The nSLAM project draws on the xjimmies library, which is a continuation of “pdjimmies” and the original “jimmies” library, developed for the ISPW (Ircam Signal Processing Workstation) and then ported to MAX/MSP.



Detection

  • pd-aubio - contains various externals for PureData using the aubio library.

Media

  • GEM stands for Graphics Environment for Multimedia and is an external (plugin) for the computer-music software Pd.
  • Pure Data Packet (PDP) - an extension library for Pure Data, providing video and other media processing functionality. PDP's focus is on images and video, but there is support for matrix processing, 1D and 2D binary cellular automata and opengl rendering (like Gem). PDP runs on Linux and OSX. The OSX version depends on Fink.
  • PiDiP Is Definitely In Pieces
  • Framestein is software for processing images and video with Pure Data. Requirements: Windows, DirectX version 7 or later, Pure Data.


  • https://github.com/jpcima/pd-visualization - This pd-visualization package provides Pure Data externals for visualizing signals. These visualizers run in external processes and do not disturb real-time signal processing. A standalone version for the Jack Audio Connection Kit is also part of the package.

LV2

  • https://bitbucket.org/agraef/pd-lv2plugin - a Pd external which provides a simple LV2 host so that you can run LV2 plugins inside Pd. The overall operation is similar to the LADSPA plugin~ external, but it works with LV2, the new Linux plugin standard. It supports both audio and MIDI plugins. lv2plugin~ is based on lilv, the reference LV2 host library, so it should work with almost any LV2 plugin. lv2plugin~ is written in the author's Pure programming language, so you need to have the Pure interpreter installed, as well as the pd-pure plugin loader and the pure-lilv module. You can find all of these on the Pure website. You'll also need the lilv library itself and the LV2 headers


VST


  • https://github.com/pierreguillot/Camomile - Camomile is a dynamic plugin made with Juce that allows to load and control Pure Data patches inside a digital audio workstation. The plugin is available as VST, VST3 and Audio Unit for Windows, Linux and Mac.

JACK

  • https://github.com/agraef/pd-jacktime - provides a basic interface to the Jack transport client API. The jacktime object observes and reports the current frame, status (stopped/rolling) and, if available, BBT (bars-beats-ticks, as well as meter, ppq, bpm) data. This information can then be used to synchronize Pd with a Jack transport master like Ardour.


Integration


  • https://github.com/Ant1r/ofxPof - a set of Pure Data (Pd) externals written with openFrameworks API, that bring OpenGL graphics and utilities to Pd, such as : basic 2D shapes drawing : rectangle, ellipse; image pre-loading, caching and drawing; mapped 3D sphere and plane; anti-aliased truetype text rendering; translating, rotating, scaling; color and alpha blending management; shared framebuffers


  • https://github.com/cuinjune/Ofelia - a Pd external which allows you to use openFrameworks and Lua within a real-time visual programming environment for creating audiovisual artwork or multimedia applications such as games.






Networked

  • netpd is a CRNMME (Collaborative Realtime Networked Music Making Environment) built in Pure Data. It allows many users to have a realtime jam sessions with each other, connected over the internet. Users might contribute their own netpd-ized patches a.k.a. instruments or use pre-existing ones. The set of instruments, as well as the state of each instrument is synchronized between clients in order to provide identical experience for every connected user.


  • SyncJams - a zero-configuration network-synchronised metronome and state-data dictionary for easy collaboration and jamming with electronic music software. It aims to be plug & play on LANs and WiFi networks and is embeddable in existing applications and music environments.
  • pd-mdnsbrowser - a stand-alone version of the OSC service browser in the pd-touchosc module. It employs mDNS/DNS-SD a.k.a. Zeroconf for the service discovery, and works with the prevalent Zeroconf implementations on Linux and Mac OS X, Avahi and Bonjour.

GUI plugin



  • GrIPD is a cross-platform extension to Miller Puckette's Pure Data software that allows one to design custom graphical user interfaces for PD patches. GrIPD is not a replacement for the PD Tcl/Tk GUI, but instead is intended to allow one to create a front end to a PD patch. The concept is to create your PD patch normally and then your GUI using GrIPD. You can then lauch PD using the -nogui command line argument (although this is certainly not necessary) so only your custom front end will be displayed. GrIPD, itself, consists of two parts: the "gripd" PD object and an external GUI window/editor. The PD object was written in C and the external GUI was written in Python using the wxWindows. GrIPD is released under the GNU General Public License.

Programming

  • http://pdstatic.iem.at/externals-HOWTO/ - Pd is a graphical real-time computer-music system that follows the tradition of IRCAMs ISPW-max. Although plenty of functions are built into Pd, it is sometimes a pain or simply impossible to create a patch with a certain functionality out of the given primitives and combinations of these. Therefore, Pd can be extended with self made primitives (“objects”) that are written in complex programming-languages, like C/C++. This document aims to explain how to write such primitives in C, the popular language that was used to realize Pd.
