Hi,
I'm having issues with an:
8-Core MacPro, OS 10.5.8, RayDAT, Midi-Over-Lan.
The computer runs Standalone version of Vienna Ensemble Pro, Bidule, Logic Pro 8 and sometimes Kontakt 4 (as standalone version).
This machine is used for hosting instruments.
When the instruments get loaded everything seems to work well, but after some time one or two hosts stops playing audio.  I have to restart the audio engines of each of the applications in order for them to work.
This has not been an issue for the last year or so when this computer was being used, but now it's becoming a problem.
I have heard that people have issues like that with RME cards.  I've seen that very same problem with RME's MADI card, but not with the RayDAT card.

Is there anything I can do to get rid of this issue?

Thanks
