so, regarding the ReaFIR; It was a spur of the moment thing for Cool to use it in combo with an EQ.. However it was a great lesson for me in learning the capabilities of Reaper plug ins for sure.
I noticed also in learning from Kenny's vid on De-essing a similar signal path from eq to comp but with a different signal routing in and out of the chain.
If I'm understanding these two chains they are basically the same thing just able to be inserted differently into a channel/track.
I think I might have hurt my mix a bit also, but it's like my first few trips to a bar when I was old enough - no experience and very little self control
