Hey Tahome,
thanks for your reply. The {2, 2}/{1, 2} combination does indeed work.
But if my plug-in is supposed to have a {1, 8} configuration? I tried
to add several second configurations to make AULab happy, but try as I
might, I can't get it to run. I always get the same error.
Interestingly enough, if I use a combination of {1,8} and {8, 8}, the
AULab at least displays the AU on the list of possible 8-channel
plug-ins. If I use {1,8} and {2, 8} instead, it doesn't even show up.
