Downloaded this baby, install went great. Load it up in Studio One V3.1 and works great. Went through quick preset and this EQ honestly sound amazing. Played with the knobs drive and all the features and this EQ got some really Mojo and is incredible on Vocals & sound fantastic. You can even use it in your Busses to go get a nice tranformer tone to the tracks or give a little character. The only thing honestly (i'm just posting this quickly as a first impression) and I must say that even though I haven't gotten to play more with and the first test run makes me smile but something really turned me OFF a bit as how CPU hungry this plugin is.
I don't know if the Beta Team did report this but on my Win 7 x64 this plugin is really hungry big time. I hope PSP gets to tweak this because it's totally unbelievable how CPU spike up as soon as you dial this baby up.
For example: I load E27 on a Back Vocals Bus in project that has some plugins running from (Flux, IK, LVC etc.. and my session also has some VI on and recorded vocals, back vocals etc..) and my project before adding E27, CPU runs at
30% ok!
When I added one instant of
E27, CPU jumped to
70% (without even loading a preset). Than added a second E27 and jump to 80%
I find the CPU usage of this pluging hasn't been really one of the main concern and hasn't been well optimized. I'm saying this because as I Beta Tester (from heavy plugins like Acustica with their Acqua Series or Nebula) well some Acqua plugin eats up less CPU than this new great release from PSP.
Hope they tweak this for version 1.01

(hope this helps) and again this is under S1 V3.1 and Win 7
Best,
