In WL6 you could pitch shift without processing at all (0% L.C. “Quick Process”, No DIRAC), only speed up or down (actually a resample). This is not possible in WL11 anymore.
Try a simple hihat and pitch it up and down a few times in WL11 on 0% and simplest settings and it will sound like crap. Do the same in WL6 and it gets slightly duller after a few generations, but retains the integrity of the sound.
