The rt language uses static typing, and tries to figure out the 
types of variables automatically. For this code, the compiler wasn't 
able to figure out "sr"'s type.

I'm not quite sure why, but I guess its because there is only a 
method call "(mus-reset sr)" on the variable in your code, and perpahs the 
processing routine must be called sometime for the type to be 
correctly set.

Anyway, just remove that "(mus-reset sr)" call that made the trouble, 
since "sr" isn't used anymore.
