Hi,
i have difficulties ( though i didn’t experiment a lot yet) to understaend the mind set behind it. im used to play and record the drums with finger drumming along the song, or record some midi parts, then edit if needed.
with pattern approach its kind of taking me out of the music for now, although of course i see the benefits of the random function to come with ideas that i wouldn’t come probably and they can fresh the style.
2: i find it hard for me to program in pattern editors, cuz if i have a groove in mind, i have to figure out where to put the hits, so i find myself entering hit and deleting until it fits what i want !
is there a way to record live to the pattern editor ? would be much faster for me to have ideas in mind recorded finger drumming than entering hits in the pattern.
maybe there is also midi event to pattern conversion ? it would help too
In this case I wouldn’t even use the pattern functionality. Having a MIDI Part recorded live as you do (and I do too) and then opening it in the Drum Editor is always a good choice 
But of course maybe in the future, Cubase will have the functionality of importing midi parts to the pattern editor, though this would make things a bit nasty in some cases, especially when we don’t want the needed quantization step.
I feel you. On the one hand, if one can directly record their drumming on a track, it seems that this new feature is not very relevant.
On the other hand, I find that I can quickly throw together some sounds (mostly percussion-style) from Backbone in a Drum Track, write an almost full pattern, mess with the “probability cloud” (velocities too) and have a quick and dirty percussion background right away. I think it’s more a matter of avoiding to notate the “wrong” notes than writting in only the “good ones”.
I guess it’s another tool to use if and when the need arises.
Pattern-based “drumming” harks back to the drum machines of the 80’s and is a completely different mind set – intended for non-drummers (and I’m speaking as one). If you can record a rhythm naturally, by any means, then I suggest regarding pattern-based entry as an optional entertainment. As you say yourself,
probably time will tell , eventually ill use my “old” methods with cubase 14 new “toys” for some seasoning i guess.
im 51 , its hard to teach old dog new tricks ! 
I also feel ya. I bought a zoom (cheap alesis copy I think) drum machine in the 90s and never bonded with it - it was actually easier to buy an electronic kit and learn a bit of drumming and get down the rudimentary pattern myself.
Bought a CMC-PD (other 4x4 pad controllers are available) for £60 and I’m happy as a pig in s***.
