Hi
I have 3 tracks routed to a slave running VEPro 5. I have noticed that when the tracks has an instance of Console 1 (Softube) assigned, Cubase will crash if I disable those tracks all together. 
Now I have tested the same 3 tracks with a Soundtoys plugin and Cubase survives when I disable all 3 tracks at the same time.
Can anyone with Console 1 installed confirm that?
