you're a bit confused. AU doesn't come with "variants". A given AU
publishes its possible I/O configurations in a way that is extremely
flexible, and can include wild-cards. A plugin can support I/O
configurations like:
1in/1out
1in/1out or 2in/2out
1in/any out
any in/2 out
any in/more than 2 out
less than 4 in/less than 8 out
3 in/less than 3 out
and many more.
its a bit misleading for a host to try to enumerate the possibilities
for a plugin in the general case, although obviously for specific i/o
configurations it might make sense. specifying a given i/o
configuration doesn't involve finding a variant plugin - it implies
configuring an existing instance of the plugin to use a given i/o
configuration - no more, no less.
if your project is GPL'ed i could point you at some code that
demonstrates one host's handling of AU I/O specifications, but i
suspect that it probably isn't (and you could find it anyway with
google if you want to).
