Are you compiling the instrument? Just pasting the source into the lisp
listener will not work. 

You have to:
a) save the instrument source in a file (for example "simp.ins")
b) compile the file with "(compile-file "simp.ins")"
c) load the compiled instrument with "(load "simp.cmucl")"
e) test it:
   (with-sound()(simp 0 1 440 0.1))
