I`ve now checked out the free version and I have to say I am quite stunned.
Apart from being an Xxxtreme cpu hog, all the fx emulations sound really very good!
While I am a hater of convolution reverbs ( they sound static and somehow dead) the reverbs on this thing sound transparent and clean and have spaciousness...
classic convolution also is not able to authentically capture EQs and stuff like that.... but the EQs (highpass, moog lpf, lowpass ) that are included in the free version sound very close to outboard mixer gear, if I close my eyes and just listend to them...
This is some decent stuff....
The only problem is after 4 EQs and 2 reverbs my system is at it limits.... lol
So not perfectly usable....

check it out there is a free demo

try that synth sweep highpass on a synth pad, absolutly great.
if you change the freq on highpasswhile playing the sound is warm and like cutting through butter.
Excellent.
