-Virtual tracks like in cubase, being able to loop record vocals over and over on the same track.
The ipad is great of vocal recording I think, but find cubasis a bit limited here or there is something I am not aware of.
-And if by any means it would be possible to use a mouse for editing it would be possible to use cubasis fully.
I know this is hanging on IOS mostly.
But this is a big one I think, especially with ipad pros if this was possible i´d get one.
