Clavilux 2000

“The Clavilux 2000 is an interactive instrument for generative music visualization, which is able to generate a live visualization of any music played on a digital piano. The setting of the installation consists of three parts: A digital piano with 88 keys and midi output, a computer running a vvvv patch and a vertical projection above the keyboard. “
