Extended DMI Model
The typical DMI model connects the musical interface with the sound generation through a mapping stage. [Fig.1] shows the extended DMI model for spatial sound synthesis. The joint control of spatial and timbral characteristics offers new possibilities yet makes the mapping and the resulting control more complex.

Mapping in Puredata
We chose Puredata as a graphical interface for mapping controller parameters to sound synthesis and spatialization. Especially in the early stage of development this solution offers maximum flexibility. [Fig.2] shows the mapping GUI as it was used by the participants in the mapping study:
