I have had a major interest in the performance practice issues in electronic and interactive systems over the years (see, for example, Kimura 1996). As a performer/composer often presenting pieces from the classical and other contemporary acoustic violin literature in traditional settings along with electronic works, and also as a teacher of interactive computer music performance at a conservatory where my students include highly trained performers, performance practice issues in computer music come up very frequently in association with the creative process. I tend to focus on creating MaxMSP patches that address a particular musical context or situation, rather than creating an elaborate versatile and reusable MaxMSP patch and then using that patch in a particular way to make music. This paper describes a few examples of my interest in this area: (i) System Aspects: Performance Practice Issues and Room Acoustics; (ii) ‘Pragmatic’ Programming and Performance of Interactive Music; and (iii) Creative Process and Interactive Computer Music.
