I've made some changes to the CM code available at http://www.wordecho.org/code/cmcode/cmusic.html These updates include interfaces to the constraint solvers Minion and Concorde in "nudruz.lisp". Minion and Concorde executables should be in your path for these to work, along with my perl scripts "concorde.pl" and "bestmatch.pl". Best, Drew Krause
