This paper describes a workflow for composers, engineers and performers to collaborate, using Pure Data (PD) as a framework, towards the design of electroacoustic musical instruments intended for live performances of sound-based music. Furthermore, it presents some considerations about live performance and ideas of creating collaboration tools, possibly as PD GUI plugins.

The Deckle Group is an ensemble that designs, builds and performs on electroacoustic drawing boards. These drawing surfaces are augmented with Satellite CCRMA BeagleBoards and Arduinos.[1] Piezo microphones are used in conjunction with other sensors to produce sounds that are coupled tightly to mark-making gestures. Position tracking is achieved with infra-red object tracking, conductive fabric...

Topological acoustics has recently witnessed a spurt in research activity, owing to their unprecedented properties transcending typical wave phenomena. In recent years, the use of coupled arrays acoustic chambers gained popularity designing topological systems. common form, an array with relatively large volume is via narrow channels. Such configuration generally modeled as full three-dimension...
