EyesWeb. V. 4.0.0.10 Beta Platform

EyesWeb is very similar to MSP MAX/NATO for the MAC, only it runs on the PC. Also it’s a free, and very flexible application.

It’s designed to assist in the development of real-time music and multimedia applications. EyesWeb supports the user (i) in the development and experimenting of computational models of expressive content communication and of gesture mapping strategies, (ii) in fast development and experiment cycles of interactive performance setups.
