Arne (& csound-list):
The demo disablement of "Save Application" means to run CommonMusic,
or CommonLispMusic, etc., one would have to load all binairies compiled
from the source *every time* you wish to use those packages. This can
take a few mins. (*understatement*). 
The nice thing about full Lisp implementations is that one can save an entire 
image of the current running lisp image: In other words, the saved image
can contain all the packages you normally work with. 
No "re-loading" (think of dll's/.so files: the code is initally compiled,
then dynamically "linked in"). This is a very nice thing, if, like me
one is impatient, and wants to get to composing in the few hours I can
devote these days to music. Not sitting waiting for code to be linked in.

Perhaps Tobias Kunze can fill us in on how long it takes to load an enitre
CommonMusic image in MCL.
The demo might be a great deal for learning/checking out CommonLisp.
I certainly have enjoyed what I've seen of CommonMusic in MCL (meaning the
GraphicUserInterface it provides, although I don't know how much use it is
once one becomes proficient at the base language and provided classes.)

Good luck, 
and thanks for the info, Arne!
