Thanks for taking the time to share your workflow Dana, very appreciated.
So it took me a while to actually understand PRO L2 properly because it is a sort of three-step processor. The lookahead prepares the transients to be affected by the clipping limiter (attack) and release does what an actual release does depending on how much attack there is since the signal sort of splits between those two depending on the settings.
I always try to keep the release as natural as possible and I find that for pop rhythm heavy music 120-300ms seems to be the spot for me. With attack I generally do not go past 60ms since it sounds a bit too distorted to me. Hats off to you if you can pull off the limiting with such a long attack. When it comes to lookahead, in the majority of my masters I do not go past 0.3ms, but there are cases (ballads, piano heavy production (think Adele)) where the transients do not matter that much (to me), and 1.5-2ms feels REALLY smooth and polished.
