I just grabbed the Serum demo for Mac; saw this video on steve duda talking about dragging samples into the noise osc. Just tried it and it won't let me drop it in. It's a 1 shot wav sample. Wondering if there's something I'm doing wrong, the noise osc is on and keyboard enabled. I can put the .wav into the preset folder and that works but the video shows him dragging the file onto the osc
