you'd just write
signal_setchans(sp[2], ouchans).
That's what I had originally suggested, but you rightfully pointed out
that changing the channel number in place can be problematic if signals
are reused...
So it would have to be at least:
sp[2] = signal_setchans(sp[2], outchans);
empty output signals (channels=length=vec=0)
But then what is the point of having the signal if it does not provide
any information?

I think I hadn't pushed them, oops. And now I'm thinking again - maybe it's
more elegant yet to provide empty output signals (channels=length=vec=0)
and instead of (for example)
sp[2] = signal_swapforchans(sp[2], outchans);
you'd just write
signal_setchans(sp[2], ouchans).

Cool!
I don't see these changes yet. Did you forget to push them or are you still
working on it?
(I am working on some clone multi-channel bugfixes and I would need the new
signal_swapforchans() function :-)

OK, just now changed this - there's a one-channel signal created for all
signal outputs. Now if you want more than one channel you have to call
signal_swapforchans() (see d_arithmentic for example).

multichannel objects must create the output signals themselves.
(as the object might change the number of channels).
even with [nchs~] where I'd have a fixed number of inputs/outputs?
yes.
with all multichannel aware externals.
how would Pd know the fixed number of outputs, if you don't tell it?
see the example (mostly: pack~)
I saw it and it's quite simple, withou a 'perform' routine it uses a copy
function.
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.
