A video I've been meaning to do for a while; a quick play through of eight of the PastToFutureSamples kits. There's several more that I haven't included, but I thought these eight cover enough. These libraries have no GUI and only cost $10 - $15 each, but are some of the most usable drum libraries I own. Recorded with period equipment, they have bags of character and get you quickly to classic 50s, 60s and 70s sounds. I usually compress the drum channel with the Waves CLA-2A (as seen) so that there's around 1-3db of gain reduction. Then use Vulf Compressor on the mix bus (as seen) for some parallel compression. The trick is to not obliterate them into one plugin but to build the compression up in stages - channel / bus / mastering. You can see the headroom and dynamics displayed on the output lights in the top right quarter of the screen.
