Re: Suggest a good compressor vst
It's not free, and it's not just a compressor, but Izotope Alloy 2 is the one I find myself using the most. It's a real versatile one and having it bundled in with the other mixing tools (including an extra compressor that you can route in serial or parallel) is pretty sweet. In the world of freebies, I like the TDR stuff already linked.
I see you have FL, have you tried Maximus (which is in-freaking-sane) or the other FL compressors (I think there's the regular one or a multiband version)?
