Dugan allows Manuel, auto, and Mute for each and every group, and allows assignments to a group to be moved to the next group at the touch of a button.
The Override feature is also very nice.
Of course, I personally prefer to use Dugan because it works a little differently.
So when using Dugan, the PreFader insert affects the same group when the fader is turned down all the way.
So a PostFader insert point is needed.
The AMM with Avantis is great, but I want to use Dugan (Waves) for different purposes.
