IMHO, plugins should not worry about whether or
not their outputs
are connected. (In fact, there are reasons why you'd want to
always guarantee that all ports are connected before you let a
plugin run. Open inputs would be connected to a dummy silent
output, and open outputs would be connected to a /dev/null
equivalent.)
In modular synth systems there are good reasons why you want to
know whether things are connected (and good reasons why they
wouldn't be), but this spec so far is not useful to a modular
synth, so in this case I agree. I'm not sure what peoples opinions on numbers of
outputs are,
obviously the number needs to be variable per instrument at
development time, but I dont think it should be variable at
instantiation time, that doesn't sound useful, and it would be hell
to optimise.
I don't see why a mixer plugin would have serious trouble supporting
1+ strips. Basic mixers strips could indeed be implemented as
separate plugins, but if you want PFL, busses and stuff, I think
you're much better off implementing and optimizing that within a
single plugin.
Besides, I bet someone can come up with something with much more
intricate inter-channel relations than a mixer...

On controls:
It seems like you need two sets, per instrument and per voice, they
should share the same interface, and the per voice ones definatly
should not be limited to modulation,chorus,whatever.
My feeling is that just float+"arbitrary opaque binary data" is
enough. The float can be augmented with hints, enumerations,
whatever.
I agree.
