I just tried this with keyswitch patches in the VE Pro 32 bit server in Yosemite. . (There are no "master keyswitch patches in the Hollywood Series, only EWQLSO so hiopefully I loaded what you did (sus-short). I was able to successfully load them for HS Diamond Vln 1, Vln 2, Vla, Celli, and Bass, and then HB Diamond for French horns, 3 Trumpets, 2 Trombone and Bas Trombone, and Solo Tuba. I continued with HOW Diamond Piccolo and then when I tried to add Flute at that point it did indeed crash.
I then tried the same thing in the VE Pro 64 bit server and loaded KS patches for all HS, HB, and HOW instruments with no crashing.
Personally, as a composer who uses these tools and gets paid as a Logic Pro consutant to help others use these tools effriciently, I have zero interest in how a 64 bit capable plugin behaves in a 32 bit host in a 64 bit OS version that was released only a week or so ago.
But if you do, email me the issue and I will gladly pass it on and see if the Play developers at EW do.
