Demos: Støjbox XYZ and Støjbox Spring

This paper describes the features, development process, and demonstration of two prototypes of new desktop instruments: Støjbox XYZ, and Støjbox Spring. The highlight of the Støjbox XYZ is a 3-dimensional controller designed to augment existing sensor technologies, thereby increasing the expressiveness of the synthesizer interface by letting musicians simultaneously access three different sound parameters with a single finger. The main element of the Støjbox Spring is a spring reverb tank that can be played directly (with the addition of an internal feedback path incorporating various effects), or used as an effect unit for other instruments. The method of iterative prototyping was used in the development of these instruments, and the work contributes with the bespoke designs and demonstrations of the prototypes.
