Free plug-ins are usually of a lesser quality and only made to get you to eventually buy the paid versions or other flavors the same company may sell. Put asses in the seats and then grab the cash later. Blue Cat has been around, a while, but I never really dove into these. Here I am just opening and messing with some presets on a few of their audio plug-ins. Nothing major, just screwing around with noise. But this video may show you what you need to know or entice you to grab em yourself. For free plugins these are great. Definitely at the top of the mark. BTW they have just about every format you could desire including AAX and RTAS, MAC and PC.
