This paper aims to present a novel interface for composing and performing with granular synthesis. The described system allows handling individual spatialization for independent groups of voices and controlling various parameters of the granular synthesis in real-time. The DMI tries to create a new interaction, outside of the norms of traditional controllers, giving the user the freedom to move the groups of grains over the space and at the same time curate the sound on a fundamental level. This paper describes the sound synthesis and the interface design as well as its various functions.
