Glad it's stable for you. OTH it hangs when recalling .vesp files that have Native Instruments Kontakt 5 instruments in them. This message pops up in an NI-style window: 'Working on sample data cache. Please wait'. It never goes away.The application was just released. Who should be able to answer your question other then the beta-testers? 😄
Here is my experience: It is so stable that I can use it on my current projects without fear of breaking something.
Also major bummed that on a Mac we lose the ability to have both 32 and 64 bit servers - it's now Windows only. If I had known that I would never have purchased the upgrade. A major part of using VEPro is being able to use both 32 and 64 bit plugins - now I've lost that and so have all Mac users. Didn't this come up in beta testing? Hopefully VSL will fix this.
Edit for additional: email sent to support about this
