Cubase has become soooo much better than it was in C7, C8, C9. Since the c10 things are improving, but I think that there is still a lot to be done in terms of performance. If you look at other DAWs, the whole interface is much smoother and more pleasant to use.
In terms of features and capabilities, Cubase has more than I will ever need.
Possibilities, the basic sound of the mixer would be nice
adapt and customize to the sound of analogue consoles. Optionally in a channel, which was easy to do with plugins, or more as a mixer-overlapping package, which was then already in the direction
Waves NLS or Slate VCC works.
As an electronics engineer, I’d like a really good emulation of the old Mackie Pule CR1604 or 8-Bus. I want the ability to send a kick drum through multiple channels and add a bit of distortion to each channel, and I want that analog touch that makes the sound so plastic. I don’t want to have to load 2-3 extra plugins individually for each sound, I want to save myself the work. Gladly this emulated console can cause extra costs. It just has to sound really authentic.
That would be the big hit for me and I would make a pilgrimage to Steinberg every year and pay homage to the decision-makers.
