Real new user here on iPad Pro. I can’t see a way to mix in video tracks to a single song. I.e. playing say a long techno track and want to transition between the video loops that come downloadable with the software. Cant open it in 2nd djay window as you appear to need an audio track as well. I just want to transition between video rather than the jolt of just selecting a different video on deck 1. Hope that makes sense?
