Scheme For Max (S4M) is an open source project that enables embedding s7 Scheme interpreters in the Max/MSP visual programming environment, the most widely adopted programming platform for computer music. Of particular note is its appropriateness for flexibly and accurately scheduling future musical events, a capability not adequately supported thus far in Max. This is accomplished by scheduling Scheme procedures integrated with the Max scheduler, and the implementation of this facility is discussed. In addition to scheduling, S4M enables users of Max to script Max generally in Scheme and provides facilities for real-time dynamic code evaluation (a.k.a. “live-coding”) within the Max environment.
