Difference between parameters and slots? / Csound

[Rick Taube]

Here is a cound example of formatting-slots to output the contents of a
slot called 'stuff' as an &rest parameter:

(defobject i2 (csound-note)
  (dur freq stuff))

(defmethod write-event ((object i2 ) (stream csound-score-file))
  (formatting-slots (object (slot-value stream 'stream)  :eol t )
     ins time dur freq &rest stuff)))

; test it out

(algorithm foo i2 (length 10)
  (setf rhythm (between .1 1))
  (setf dur (interpl count 0 .2 9 10))
  (setf freq (item (pitches c4 d ef f g in heap)))
  (setf stuff (list 1 (pick '(a b c) ) (between 10 20))))
