Pure Data (Pd) presents the ultimate, free software environment for sheer audio, video and hardware pluggabilityg. Pd provides the basis for all manner of audiovisual performance and trans-media installation, as well as satisfying the artistic quest for heady experimentation and improvisation. Yet few artists take the time to master a solid foundation in this graphical programming environment.

During a period of three days, the workshop aims to provide a firm grounding and clear overview of the varied possibilities and paths offered by Pure Data. The first day will introduce Pd and quickly move on to how to create patches which create sounds and noises. The second day will look further at sound, particularly how to work with sampled audio, and will introduce the GEM library for working with live and recorded video. The third day will start with a look at the HID (Human Interface Device) system for getting sensor input into Pd, and venture into to using this input to control the audio and video patches which the participants have already created. No previous experience is necessary to take this workshop.

This PD workshop will be roughly based on the Pure Data FLOSS Manual, written by Derek Holzer, Luka Princic, Adam Hyde and contributors from the PD community:

Participants should bring their own laptop running GNU/Linux, Mac OS X or Windows, and with Pure Data Extended installed from:

They are also encouraged to bring their own ideas, sensors, USB game controllers, MIDI devices, microphones and video cameras. There will be an opportunity to buy the inexpensive xxxxx-HID sensor input board produced at Pickled Feet:


Derek Holzer [USA 1972] began working with Pure Data in 2001. Since then, he has taught and performed with the program across Europe, North America, Brazil and New Zealand. His work focuses on field recording, networked collaboration strategies, experiments in improvisational sound and the use of free software such as Pd. He is
currently writing a beginner’s manual for Pure Data.

Martin Howse operates within the fields of discourse, speculative hardware (environmental data in open physical systems), code (an examination of layers of abstraction), free software and the situational (performances and interventions).
