[CM] CM patterns as 'CL stand alone'

[Torsten Anders]

Dear all,

Anders recently announced an OpenMusic Pattern library, which extracts most of Rick’s pattern classes from Common Music. Based on that effort, I now created a version of that library for plain Common Lisp (an ASDF system). That code is available at the link below.  

	https://github.com/tanders/cm-patterns

My immediate goal was to make Common Music patterns available in Opusmodus (http://opusmodus.com). 

Note this code is perhaps not yet as portable as the original Common Music 2 sources. Because Anders’ library was only meant for OpenMusic, some code ensuring compatibility with various Lisp compilers was removed. I reintroduced some of the compatibility code so that it now also runs under CCL, but I did not test it with other compilers yet.

Best,
Torsten
