I also posted a new thread including some details about this issue.
Actually the most problematic issue is that we cannot use the remaining scenes ( A B C D) in Hybrid mode. For example in Fractal AX8, I could assign bottom row to my prioritized scenes and also sometimes a 5th scene on upper row and the rest stomp boxes or some task switches like amp x/y or Control Switch etc… However even with this setup, whenever I want to engage a scene which is not assigned to any switch in this preset setup, I could recall it by pressing Scene select switch and pressing again to that corresponding scene number.
So every scene is usable that way. QC should find a workaround definitely.
