Vuzik: a Painting Graphic Score Interface for Composing and control of sound Generation

find an aesthetic balance between the human and the computational. The iterative generative system can quickly fall into patterns that become either repetitive or overly chaotic. Finding the creative " cusps " teetering between these two extremes was the most rewarding aspect of the performance. While some of the results of interconnecting multiple feedback layers are unpredictable, the performers nonetheless begin to have an intuition as to how their actions will update the overall composition. For example, while there is no direct mapping of how the visualization data will update the compositional structures, after some experience using the iPad interface, it becomes clear that certain gestures during certain kinds of passages generate a particular shaping of the composition. We also found it interesting to re-conceive the performers role as a " guider " of aesthetics, rather than as a creator. A possible direction for future versions of the piece would be to more explicitly highlight the effect that an interaction has as it is transmuted from one medium to the other. Although the focus of the piece has been on interconnecting different feedback loops, one obvious feedback cycle that we did not attended to is the incorporation of the audience as a co-performer. Though adding extra elements to the piece increases the difficulty of maintaining aesthetic balances in the visual and aural domain, a careful integration of audience interaction in future versions of the piece will incorporate audience members as participants rather than as passive viewers.
