While the X64 version of Rapture Pro seems to be OK, I'm having problems with the update 4 X32 version. I'll give an example that seems to be somewhat consistent on my system. With Rapture Pro Factory Library selected: Orchestral Stacks: Choose "Cathedral Ensemble": After that preset is established, then choose "Big Mix Choir". That preset attempts to load but loading process is never accomplished. Most other computer functions are frozen at that point. If you attempt to X out of Sonar, there is a crash. Again, the X64 version does not seem to have this problem.
Also, in an unrelated issue, I've noticed the multi-sample file sizes are far less than in previous versions. In the old versions I had well over 14 GB in multi-samples; in the new version it seems to be around 5.15 GB. I'm considering that perhaps there are more Flac files in the new version, but I'm not sure yet.
