Hello Paul,
Yes, it happens even with a new arrangement. My Cubase version is 6.5.1, build 117. I can reproduce the crash easily (Cubase 64 bit this time):
- Create a new project.
- Create an instrument track with VI Pro 2.2.10738
- Load a matrix, for example VI-Pro Matrices->Orchestral Strings->Violins Orchestra->SE VI-14 01_basic
- Activate / load "sus" cell.
- Turn on the reverb button
- Play some notes
- While notes still sounding, turn off the reverb
If not happening the first time, just keep trying turning the reverb on and off a few times. I did it while I was typing the steps and crashed it the second time I switched the reverb button off.
Crash log (sorry, in Spanish)
