With Kontrol, a music application for iPhones and iPads, users create techno compositions by clicking on a simple interface of four blue squares, each of which moves and triggers certain sounds and beats. The sounds and the squares’ movements depend on the order and manner in which the squares are activated and the structures that result. While the rules for modifying the soundscape are quite rigid, there is also a random element to the audio and visuals, so that trial and error become part of the game. Complex compositions can be constructed by layering multiple sounds and beats, and the lack of precise control becomes the very mechanism for creativity.
