A very small program called GSFIX automatically changes the priority that GigaSampler sets for process msg32.exe from \'realtime\' to \'high\', allowing better coexistence with VST. The link for the program can be found within the GS section of FAQ on the RME website: http://www.rme-audio.com/english/index.htm

This may be old hat to many of you, but I thought it might help some folks, like me, who are new to GS. Thanks to killerbobjr for some optimization and partitioning insight.
