The significant predecessors of both wigout and TrikTraks are SAWDUST, designed by Herbert Brün and written by Gary Grossman, Jody Kravitz, and Keith Johnson at the University of Illinois [3, 8], and SSP (Sound Synthesis Program), designed by Gottfried Michael Koenig, and realized by Paul Berg, Robert Rowe, J.D. Banks, and David Theriault at the Institute for Sonology, Utrecht [2]. These programs can be classified as ``non-standard sound synthesis programs,'' following S. R. Holtzman's definition [7]. Paul Berg's description of SSP is appropriate for TrikTraks: ``... [it is] best suited for a user who wants to define structures and listen to the results rather than a user who at all costs must have a certain sound.''
