Load up the presets in the "Vintage" folder and you can see the different approaches. For example, the 1176 presets employ the nonlinear response and release adapt with a fast attack and release. The LA2A presets use the RMS window to simulate the opto lag with long attack and release times, and you'll notice the nonlinear control is also used. On the VariMu ones examine the really soft knee, low ratio, large RMS window for gentle bus compression.Ploki wrote: Mon Feb 11, 2019 12:46 pm i'm not sure how it models different types like VCA/Opto/VariMu
If you haven't seen it, check out Dan Worrall's latest video on YouTube about Reaper's compressor. It's not just about ReaComp, it's a wealth of information about compression in general condensed into a half hour. And by the end of it you should be able to roll your own 1176 style presets.
