Hi There,
I don’t have an M1 but do have an N1 and in the Global parameter section you can adjust the velocity curve of the keyboard so see if you can globally adjust the velocity curve of your keyboard which will resolve your issue?
If you can’t adjust the velocity curve a slightly painful workaround would be to adjust the velocity compression under the Midi Modifiers tab in the Inspector! The default is 1/1 but if you change it to 2/1 or even higher you will notice the velocity curve change for the better.
The reason I said it’s a slightly painful workaround is because you will have to adjust it for every track you use drums on! 
Anyways, I hope this helps?
Kind regards
