[CM] cm and supercollider

[Johannes Quint]

i've tried out the super-collider examples (/etc/examples/sc.cm).
everything works fine until i try to play something. after:

(events (sc-simple-5 10) "sc-simple-5.osc" :pad 10)

an aiff-file starts but nothing to hear.
the same with the real-time examples in the dictionary.
after:

(define *sc* (sc-open))
(rts (sc-simple-3 10) *sc* ),

i receive the following error in super collider:

FAILURE /n_set Node not found

thanks for help, johannes
