What is a Casm?
The CASM is a part of a style file that tells the PSR how to process the file. It provides information on what track(s) should be played as specific parts (e.g. Bass), the key, and a number of settings that can alter the sound during playback. You can see what the CASM looks like with the program StyleDump available at http://www.svpworld.com/psr_software.htm#stylemanager and detailed information is available at: http://home7.inet.tele.dk/js/musik/740pages/articles/casm.
