The „reactable“ is a state-of-the-art multi-user electro-acoustic music instrument with a tabletop tactile user interface. Several simultaneous performers share complete control over the instrument by moving physical artefacts on the table surface and constructing different audio topologies in a kind of tangible modular synthesizer or graspable flow-controlled programming language.
The instrument was developed by a team of digital luthiers under the direction of Dr. Sergi Jordà. The "Interactive Sonic Systems" team is working in the Music Technology Group within the Audiovisual Institute at the Universitat Pompeu Fabra in Barcelona Spain. Its main activities concentrate on the design of new musical interfaces, such as tactile music instruments and musical applications for mobile devices.
