I put together a short review video on the Pioneer DDJREV1 controller and how it works with the new STEMS. This controller works well with Stems. The Rev1 controller has a lot of cool new features that Pioneer added. I'm still getting familiar with this controller since I had SB3 before this. I lack a lot of knowledge with a lot of features on this deck. The DDJRev1 is a battle style controller and to me, it's a lot easier to use. I tried my best to go over some of the features. Stems is still glitchy at this point and requires a beefed up new Mac or PC. I'm now officially in the market for a new Mac lol. Please let me know if there is a review that you want to see or let me know if I left something out. Thanks for watching!
