Loops, Virtual Voices, Mixer Plugins

Question

I'd like to use Playback Priority to allow only 20 loops (infinite continuous random containers) at a time. So, low priority loops stop playing, but once their priority climbs up they start playing again.

 

Main question here: Can this be done without using Virtual Voices?

 

My problem is, that some HRTF Mixer Plugins don't have a priority system, e.g. they don't exclude Virtual Voices from their processing, which wastes valuable HRTF channels on non-audible sounds.
