Just installed and trying out the latest Vienna Ensemble Pro (6.0.15415) & Vienna MIR Pro (5.4.15393). Unfortunately it still seesm quite buggy. Some of the issues so far include:
1. Keep losing control in the MIR Pro window when trying to click in or resize it. Seems to happen randomly. Have to close and reopen the window in order to be able to click inside it again to move instruments around. Not sure if this has to do with the VEPro 6 update or the MIR Pro update, hoever, it makes it unusable, especially to reposition instruments or resize the stage.
2. Whenever opening an existing project from Cubase, VEPro 6 window sizes seem to return to default and you have to resize them again. Did not happen in version 5.
3. Selecting plugin channels for software such as Kontakt 5 or other samplers/synths seems much slower response at times before it changes over to the new plugin. VEPro 5 was instant. Seems to be worse with AU version (such as Kontakt) thatn the VST versions (even though VEPro 5 only used AU plugins).
4. Other random crashes which I currently cannot reproduce when trying to.
The program is definitely easier to read at this point than v5 was, especially on high def monitors. Unfortunately, I may have to go back to VEPro5 until the software becomes more stable/reliable. Was hoping by this time, it would have been a bit more usalbe.
