[CM] weighting not recognized

[Dan Corneliu Georgescu]

Hi,
Following example doesnot work because “weighting does not name aclase”. 
(define(chordy)
  (let ((pat (new cycle :of (list
                            (new chord :of '(c4 e4 g4))
                            (new chord 
                              :of (new heap 
                                    :of '(df4 ef4 gf4 af4 bf4 df5 ef5)
                                    :for 3))
                            (new chord :of '(e4 a4 cs5))
                            (new weighting 
                              :of '(bf3 (ef1 :weight .5 :max 2))
                              :for 1)))))
    (process repeat 32
             do (doeach (k (next pat))
                  (output (new midi :keynum k:time (now))))
             wait .5)))
Could anyone please  help me tosolve this problem? Thanks!
