This paper presents results from the development of a digital musical instrument which uses audio feature extraction for the control of sound synthesis. Our implementation utilizes multi-band audio analysis to generate control signals. This technique is well-suited to instruments for which the gestural interface is intentionally weakly defined. We present a percussion instrument utilizing this technique in which the timbral characteristics of found objects are the primary source of audio for analysis.
