I'm on Mac OS 10.5.8 (Mac Pro 8-core 2x2.8GHz with 10GB RAM), running Sibelius 6 with VSE+ and the latest version of both Sibelius and the Vienna Ensemble. I've got quite a few instruments in my Playback Devices, so I need to launch three instances of the VE plugin (one for the strings, one for the winds and one for the brass and percussion), each instance having a VSL Convolution Reverb of the VSL Suite on its Master Bus.
However, the three instances of the plugin open in the same VE program, which results in the program reaching almost 3GB of Real Memory and 4GB of Virtual Memory, and using over 80% (of one core) even when the playback has stopped.
Then, it seems that I cannot do anything anymore with the Vienna Ensemble, or it crashes. I can't add an instrument, I can't minimize it in the dock, I can't hide it... Everytime it crashes.
On the other hand, if I start a new project that needs less resources, I do not meet any problem.
Does anyone have a clue on what is going on and how I could fix this problem? Is there a way to launch every instance of the VE plugin in a different VE program, so that each one uses far less that 4GB RAM and 80% CPU?
