Sonigraphical Instruments: From {FM}OL to the reacTable*

This paper first introduces two previous software-based musicinstruments designed by the author, and analyses the crucialimportance of the visual feedback introduced by theirinterfaces. A quick taxonomy and analysis of the visualcomponents in current trends of interactive music software isthen proposed, before introducing the reacTable*, a newproject that is currently under development. The reacTable* isa collaborative music instrument, aimed both at novices andadvanced musicians, which employs computer vision andtangible interfaces technologies, and pushes further the visualfeedback interface ideas and techniques aforementioned.
