This paper considers the issue of computer-assisted composition in formal music education settings from the perspective of critical theory. The author examines the case of MIDI-based software applications and suggests that the greatest danger from the standpoint of ideology critique is not the potential for circumventing a traditional understanding of theoretical knowledge and notation when composing. Instead, it is false subjectivity, or the potential belief that what one creates is free from the mediation of tacit musical conventions and the ideological biases of the technology itself. Developing a framework for critique that is partially based on the writings of Theodor Adorno and draws on a dialectical conception of composing, the author applies this framework to the issue of MIDI-based composition in order to make this case.
