Powder box: an interactive synthesizer with sensor based replaceable interface

Abstract

In this paper, the authors introduce an interactive synthesizer, "POWDER BOX" for use by novices in musical sessions [1]. "POWDER BOX" is equipped with sensor-based replaceable interfaces, which enable participants to discover and select their favorite playing styles of musical instruments during a musical session. In addition, it has a wireless communication function that synchronizes musical scale and BPM between multiple devices. "POWDER BOX" provides novice participants with opportunities to experience a cooperative music performance. Here, the interaction design and the configuration of the device are presented.
