Evaluating computer-based musical instruments from the perspective of listening

This paper presents a method of evaluating computer-based musical instruments. The method is based on a paired comparison of sound files produced by the instruments to be evaluated. The same input signal imparting performers' actions to generate musical expression is applied to different instruments. Each output is recorded and the different recordings are compared by listeners in relation to factors relevant for musical expression. A study using this method is presented. The results show that there are significant differences between the instruments compared and that the evaluation method used allows insight into specific features of the evaluated instruments. The method used in this study can be adapted to compare and evaluate new developments in the field of new interfaces for musical expression providing the same input signal can be used and fed into the instruments.
