When I change sounds in Stylus RMX using logic 6.4.2 it creates a Really nasty digital sound almost like a stutter edit and freezes logic. I'm usually unable to force quit and have to restart my G5 (2Ghz 4Gig ram 2TDM farm cards) from the on button. The other scenerio is when going through sounds in RMX, it trashes all my virtual instruments. I'm able to play audio and midi but no sound comes from the virtual instruments.
I suspect it's got something to do with the esb and PTHD tdm hardware. Any ideas out there?
