If it was done by the DSP then there is a possibility you could disable it with Hijack. Unfortunately, I would say it's done in software - I don't remember reading anything about a stereo bleed function in the DSP manual

I'm back at 3.00a3 for exactly this reason. Started to find a few 3.00a5 issues though it is much more stable than 3.00a3
