[CM] Example error in common music dictionary

[Alexandre Ficagna]

Sorry, I forgot the example:

(define (play-pats pats trope reps rate)
  (process <file:///usr/local/lisp/cm/doc/dict/process-mac.html> with
dur = (* rate 2.5)
           repeat reps
           for len = (pick
<file:///usr/local/lisp/cm/doc/dict/pick-fn.html> 8 12 16)
           for pat = (make-instance (next
<file:///usr/local/lisp/cm/doc/dict/next-fn.html> pats)
                                    :keynums trope
                                    :for len)
           each k in (next
<file:///usr/local/lisp/cm/doc/dict/next-fn.html> pat #t) as x from 0
by rate
           output (new
<file:///usr/local/lisp/cm/doc/dict/new-mac.html> midi
<file:///usr/local/lisp/cm/doc/dict/midi-cls.html> :time (+ (now
<file:///usr/local/lisp/cm/doc/dict/now-fn.html>) x)
                       :keynum k
                       :duration dur)
           wait (* rate len)))

;;; a pattern of pattern class names
(define pcns
  (new <file:///usr/local/lisp/cm/doc/dict/new-mac.html> weighting
<file:///usr/local/lisp/cm/doc/dict/weighting-cls.html> :of '((heap
:weight 2) line cycle
                    palindrome rotation))

(events <file:///usr/local/lisp/cm/doc/dict/events-fn.html> (play-pats
pcns '(a4 b c5 d) 12 .1) "test.mid")
=> "test.mid"

The error messages listed before occurs when evaluating "play-pats".
