Introduction Max/MSP (Puckette, 1988, Zicarelli, 1998) is a realtime signal- and event-processing environment for music. The Sound Description Interchange Format (SDIF) is a framework for representing high-level sound descriptions such as sum-of-sinusoids, noise bands, time-domain samples, and formants (Wright, et al., 1999, Wright, et al., 1998). Many of these sound descriptions are mutable models, affording operations such as filtering, morphing, pitch shifting, and time stretching (Laroche, 1998). We describe the situating of these models within an environment that provides a variety of ways in which to do the mutating. 2.# Representing SDIF data in Max SDIF data consists of time-tagged frames, each containing one or more two-dimensional matrices of data such as floating-point numbers and a frame type ID indicating what kind of sound description the frame represents. For example, an SDIF fram
