Hey guys, first time poster here. I’m recording in GarageBand & I have pioneer Dj DM-40 speakers along with a mac and a Scarlett solo interface. I have the speakers plugged into my laptop, and the headphones plugged into my speakers. Now, I would like to use an additional pair of headphones to hear along while someone else is recording. Where and how do I plug in the additional set of headphones so that I can hear?! It’s driving me nuts. Any feedback would be greatly appreciated!
