Kraftwerk [SEP] Technological innovations
According to Fritz Hilpert, "the mobility of music technology and the reliability of the notebooks and software have greatly simplified the realization of complex touring setups: we generate all sounds on the laptops in real time and manipulate them with controller maps. It takes almost no time to get our compact stage system set up for performance. [...] This way, we can bring our Kling-Klang Studio with us on stage. The physical light weight of our equipment also translates into an enormous ease of use when working with software synthesizers and sound processors.
