I have not been able to get Sibelius 5.1 and VE to work together on my Mac Pro. Both programs freeze.
I do not have any trouble with VE standalone instances when running them via midi (with Sibelius on another machine)
I do not have any trouble getting Sibelius to work on the mac pro as long as the VE vst files are not in the plugin folder.
It is a little frustrating with such a powerful mac not to be able to get Sibelius and VE running at the same time.
Any help would be appreciated.
