Hello Nate. This type of attack level fluctuation can not be handle very well in Nebula. You can try with other type of compressor library, "snap" types for example. You should also use some ahead time and HPF in the SC.
melon jack, yeah i meant any nebula comp does it. 76D isn't my comp, so your example just proves me right about that.
the fact of the matter is that nebula comps are still flawed and that's probably the biggest problem with them. i've only slowly come to realize how bad nebula is at handling bass myself, but it's one of the reasons why i've always charged usually under 20$ for my comps, and haven't ever claimed that they are just like the hardware. even with that limitation i feel like they are still worth that much.
it's a nebula flaw. it'd be nice if acustica found some way around it... the best solution would have to come from them.
but i have some ideas for solutions on my end, which won't be perfect but would be better, if they work out.
