its easyer to just have each synth with is effects all right there right by it, and I do want multple synths to have the same effects, I usually use a minimiximiser
with kobalts tho, there alot smaller and simpler. I dont need centroids b/c I never usually mess with aux's. usually each synth requres a different kind of effect and it kinda gets confusing for me if I have an aux effecting a synth along with the synths effects with it
