Everyone -- Version 1.4 (MaxMSP 4.x) and 1.5 (Max5) of the [chuck~] Max/MSP object are available for free download: http://music.columbia.edu/~brad/chuck~/ for Macintosh OS X (10.4 and 10.5). The new [chuck~] object is up-to-date with the latest (v 1.2.1.2) release of the ChucK language, including the LiSa live-sampling unit generators and the unit-analysis generators in the 1.2.1.2 package. [chuck~] imbeds the ChucK music-programming language in Max/MSP, bringing a sophisticated set of synthesis and signal-processing tools into the Max/MSP environment. [chuck~] also features an advanced timing and scheduling system in addition to a functional-style programming interface for algorithmic operations. Full source for the object and the language are also on-line. No Windows XP version is available at present -- sorry! This is a fun object -- enjoy it!
