Welcome, Ethan.
I’m a noob here as well, but I hope you enjoy your stay all the same. The Mixtrack is an awesome introduction controller, everyone I’ve known who’s owned one managed to get the most out of this unit. Never used Djay, but I’ve seen many videos posted of DJs absolutely going HUGE with the program. In truth it’s only “amateur” if you sound amateur with it.
Checked out the mix. Dude, you have no fear on the jogs ! ! Made me miss the backspin on my old Vestax even more . . . I don’t have any constructive criticism, I’d just advise you to keep training and defining your sound while working on beat matching (Perhaps beat griding if you rely on sync) and mixing. The energy was infectious though, fun mix indeed
