I don’t know how many have seen the video for the Yamaha Nuage controller (YouTube), but there is a view of the mix console which has the waveform view - as in the track arranger, but scrolling vertically instead of horizontally.
It has been stated in some promos, that the mixer in cubase is taking over from the arranger as the primary screen.
Is this perhaps an indication of what we might expect in a future (next?) version?
If so, please don’t eliminate the arranger window entirely!
