This post is about side chaining: How do you route the external source (kick) to the relevant track with C2/MB on it?
I’ve tried sending the kick to a return track. Then send the return to the bass. But that won’t do it. It’s just so much easier using the built in compressor, as it has a drop down menu and you can just chose what ever track you desire. But at the same time I’d love to use PRO C2 and MB, as they are superior plugins.
