I own VSL SE Volume 1 Bundle. I while ago I tried all the MIR extensions and I found they positioned every instrument pretty fine even with the dry/wet knob at 0. Because VSL SE is not my main library and the high CPU demand for separate reverbs on each track are too high for my computer, I look for a solution without MIR extensions.
I found an OK solution to push the instruments back with pre-fader aux-send reverbs. My main problem is panning. As long as the stereo-width remains as recorded the samples sound decent. However, when I reduce the stereo-width they sound rather awkward which is not a problem when MIR extensions do the panning. So my questions is: is there a certain trick to pan VSL instruments that doesn't destroy the sound?
