[CM] problem of rythm in CMN

[Willy Rouaix]

Hello list ;)

I try to write a drum partition in CMN, I'm a beginer. so I did it in
musixtex, and the result is here :
http://naeco.free.fr/divers/rigodon.pdf

this should be in CMN :

(cmn staff
    (b5 (rq 1/6))
    (b5 (rq 1/6) (tremolo (tremolo-slashes 1)))
    (b5 (rq 1/6) (tremolo (tremolo-slashes 1)))
    (b5 (rq 1/6))
    (b5 (rq 1/6) (tremolo (tremolo-slashes 1)))
    (b5 (rq 1/6) (tremolo (tremolo-slashes 1)))
;it's the same rythm, but not the same graphic
    (b5 (rq 1/6) begin-beam)
    (b5 (rq 1/6) (tremolo (tremolo-slashes 1)))
    (b5 (rq 1/6) (tremolo (tremolo-slashes 1)) end-beam)
    (b5 (rq 1/6) begin-beam)
    (b5 (rq 1/6) (tremolo (tremolo-slashes 1)))
    (b5 (rq 1/6) (tremolo (tremolo-slashes 1)) end-beam)
;not really I want
;after read this
:http://recherche.ircam.fr/equipes/repmus/RMPapers/delerue98/index.html
I try :

    (((b5 (rq 1/3) (tremolo (tremolo-slashes 1)))
      (b5 (rq 1/3) (tremolo (tremolo-slashes 1)))
      (b5 (rq 1/3) (tremolo (tremolo-slashes 1))))
     (rq 1/2))
    (b5 (rq 1/2))
    )

;but clisp say to me this code "is not a function"

it's true, but I don't have another idea ! could you help me please ?

I thank you for your help
