I’m still exploring but I love frequency 2. While not a plugin, I also love the channel strip for every track.
Least favorite so far would maybe be the compressor. It is not bad at all and does what it needs but kind of meat and potatoes. I prefer my Black Rooster compressor or something with more color than this.
The standard compressor is a very good tool. I use it a lot for audio post. It has a hold-function and you can choose peak or rms detection.
I love the stock compressor! Especially since I use the stock channel strip a lot. It’s right there, instantly on every track ready to do some good, clean compression straight from the mixer. I especially like to Quick Link a stack of BG vocals and dial in the same compression settings for all of them super quickly.
