Yes that's right!!!
I have the same experience. And this is a Major Prio. For example, when you create a Kontakt VST2 instrument, you will see the memory increase in the Windows task manager. As soon as you turn off the instrument, you will see the memory decrease in the Windows task manager. If you do the same procedure for a Kontakt VST3 instrument, the memory in the windows task manager will remain unchanged. This is very annoying for the efficient use of memory. I myself use midi controller automation to turn instruments on and off and this is also a great feature in Vienna Ensemble Pro 7. I hope that VSL solves this problem soon. Hope to hear from you Paul? Because I will continue to support your excellent products!
