u mean it sounds emulated / fake?

I don't like the sound of Arturia, (CS 80, Moog) nor Virsyn (Tera, Cube). Fogged, no bright sound no good basses. I prefer the sound of NI Fm7, impOSCar, some reFX, or NI absynth.
This last one is in my opinion the best sounding of all VST instruments available for Mac Os 9, is a shame it have a ugly and alien interface, and the patches always try to sound too "acid" to my taste.
Just an opinion.
