Groove Agent 1 - Basic Question

I am new to using Groove Agent 1 - I have used cubase since V 2. I am trying to figure out how to separate drum sounds to separate mixer channels where I can add processing effect (reverb, echo etc), not midi effects. I see where you can assign the sounds to different outputs, but I don’t see those separate outputs as input sources on audio mixer channels. Am I missing something? I have read through the manual and can’t figure this basic thing out. Thanks for any help.

Operation manual p. 208 “the VST instruments window” ->the “Activate outputs” button

Tanks! It Woiked!
