That's why I put a stereo enhancer after or before a S.Detune. Then I fine tune the mix of each of the effects. I've gotten good results by doing it that way.
Yes, however it's not exactly going to sound great when it comes out on speakers because of phasing issues. I learned that a few years back after someone pointed it out. It may sound good in the studio but if you're in the club listening, it's not going to sound right
What do you mean exactly by "stereo separation"?
