[sc-users] array as an arg

[Dan Stowell]

Just to add to Julian's response: you can't change the size of the
array once you've stitched it into a SynthDef. People often ask this
question, because of course it'd be nice if you could - but it just
isn't practical, since a different number of channels at any point in
the def is basically a different graph definition.
