ReacTable

The reactable, is a state-of-the-art multi-user electro-acoustic music instrument with a tabletop tangible 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 reactable intends to be:

• collaborative: several performers (locally or remotely)
• intuitive: zero manual, zero instructions
• sonically challenging and interesting
• learnable and masterable (even for children)
• suitable for novices (installations) and advanced electronic musicians (concerts)
