The reacTable in campusbot, campusparty, Valencia 2008.

Video by criadobot:

Specifications, collaborative electronic musical instrument with a tangible interface based on a table, and inspired by modular synthesizers of the sixties. It was developed by the Music Technology Group at the University Pompeu Fabra in Barcelona, a research team composed of Sergi Jordà, Marcos Alonso, Günter Geiger and Martin Kaltenbrunner.

Multiple simultaneous users share total control over the instrument by moving and rotating physical objects on the surface of a bright circular table. Manipulating these objects, representatives of the classical components of a modular synthesizer, users can create complex and dynamic sound typologies, generators, filters and modulators, in a kind of tangible modular synthesizer.

There are only 5 reacTable, which included the one that was sold to Icelandic singer Bjork.

This video is great – it shows off the ReacTable’s sexy tangiility – without even understanding the instrument, you can see clear relationships between what the performer is doing and what you are hearing.
