Splicing sections

[Ross Mohn-2]

I'm trying to do what I think should be a simple task, but I can't seem
to get my head around it. I'm probably missing the obvious.

I have a piece with a couple of introductory sections, then the main
part, and finally the conclusion. Each is defined in a separate function
with its own _process_ statement (Lisp, not SAL). How do I easily splice
these together end-to-end. Does the absolute time parameter to _now_
help me? I'd rather not have to calculate the elapsed score time
manually. Do I have to keep track of it in a global variable?

Thanks -Ross

it sounds like you are using cm2 so ill assume that in this  
answer...first, if you know how long the sections are ahead of time  
then you can simply start them at the appropriate times, say 0 30 90:

(events (list (intro) (main) (conclusion))
        "foo.mid"
         '(0 30 90))

if you dont knwo how long they last you can use the 'finally' statment  
to chain them:

(defun intro ()
   (process ...
            output ...
            finally (sprout (main) :at (now))))

(defun main ()
   (process ...
            output
            finally (sprout (conclusion ) :at (now))))

(events (intro)
         "foo.mid"
         0)


hope this helps!

Yes, both answers are exactly what I needed to know! The daisy-chaining
ability of the 'finally' statement is what I need now.

Thanks much!!
