Live-electronic transformation of audio material in an improvised context requires very fast access to the given effects. Therefore hardware controllers are mandatory when using Max/MSP. In many cases numerous knobs, buttons, and sliders are provided, but the performance still lacks flexibility, when a quick reaction is needed. I found that the shape of a gamepad in combination with the reduction of possibilities (4 buttons, 2 triggers, x-,y-axis) fits this task much better. At the moment I try to explore ways of building patches in Max/MSP that create a versatile instrument in combination with the gamepad. Always relying on the idea of only transforming external audio material, this is meant to be used in improvised and compositional contexts.
