[CM] emacs, slime fancy commands, clm

[James Hearon]

Hi,
It took me a while to finally grok this--to be able to write code in a .lisp file and compile and load it, but it seems something called slime fancy commands provides an answer.

M-x slime-compile-and-load-file

(definstrument examp1 (start-time duration frequency amplitude)
  (let* ((beg (floor (* start-time *srate*)))
     (end (+ beg (floor (* duration *srate*))))
     (j 0))
    (run
      (loop for i from beg below end do
        (outa i (* amplitude (sin (* j 2.0 pi (/ frequency *srate*)))))
    (incf j)))))

(with-sound () (examp1 0 3.25 440.0 0.75))

So I can do this all in one step in emacs now (after M-x slime, then (load "all.lisp")), and that helps with tweaking the instrument code in the buffer as opposed to loading and compiling an .ins file.  I guessing that's probably going backwards in terms of how/why those files (.ins, .fasl, .clm) developed, and once the instrument is tweaked out, then I can see it's probably best to go ahead and create an .ins file out of the .lisp file, but the .lisp file seems to make it easier for designing instruments in the emacs editor.  

Am I on the right track here, or is there some compelling reason to employ .ins files in CLM for designing an instrument in the emacs editor?

Regards,
Jim

Does that approach not work?
