Hi,
we just released a new version of cage. It cointains lots of bug fixes and improvements, as well as some new modules: most notably, a set of abstractions dealing with chord sequence SDIF data, courtesy of project supervisor Éric Daubresse.
Please notice that cage 0.3 requires the just-released bach 0.7.8, which in turn is compatible with Max 7.0.1.
Enjoy!
