TouchNoise is a multitouch noise modulation interface designed for musical live performance. It allows the direct and indirect manipulation of sound particles in the stereophonic frequency spectrum. In order to increase Touch- Noise's playability we conducted a comprehensive interface revision retaining only its core interaction concept. New interaction techniques and gestures for radial menus, effect range settings, and frequency band effects are introduced. The revision paved the way for a series of new functionalities, such as ocking, ow fields, and MIDI connectivity, making TouchNoise a fully-edged, powerful interface for creative work with noise. This paper introduces the new TouchNoise interface and functionalities through a discussion of the revision process and derives interaction principles and design recommendations for musical multitouch interfaces in general.
