How do I use Mastering Assistant and Reference Tracks simultaneously in Logic pro?

Hi there,

I would personally use a third party offering like "Reference" by Mastering the Mix which is hosted on the Stereo Output. It allows you to reference another track while not having it be affected by your Mastering Chain.

There are other workarounds if you have multiple inputs and outputs on your interface and a headphone amp or separate interface as well.

Hope that helps,
