yes.
with all multichannel aware externals.
how would Pd know the fixed number of outputs, if you don't tell it?

the interesting part is the "dsp" method.
you cannot change the number of output signals in the perform routine 
(that is: every tick).
but you can change  (or rather: must set) it when the DSP-graph is 
created, thus in the "dsp" method.
