For me, it is stages. Record and edit in the arrange. Plugins, routings in the mixer. Then the monitor view goes to desktop then I mix with my 24 faders on my mackie setup. I will return to the mixer and arrange in cubase for certain things like plugin or vsti riding. If the new mixer views cascaded to midi mixers (hiding channels) like in v6, it would be great. I don’t think I ever actually mixed in the arrange window. Just fine tuning automation.
