Hey, I downloaded some plugins for Cakewalk but only some of them were found by it. I scaned all folders and nothing. I'm talking about plugins for example: Sitala, Samplab, Komplete Kontrol. Maybe there is other way to install them to my Cakewalk? I've searched for the solutions on YT and nothing... :( I would be very blessed for any of your help
