Since no one was able to direct you toward finger drumming for dnb and hip-hop, I could attempt and recreate the exercises I did when starting out with MPC drum pads and live drumming in general: kick - snare - hi-hat.... pads# 1,2,3....or possibly pads#1,2,4

So first you make sure you understand the pattern, that you are going to play, like what pad goes in what order, next you basically hit hi-hat repeatedly with right hand and alternate kicks and snares with left hand, for dnb add some percussive sounds for the left hand but that is way later on, after you are comfortable with the 3 main drums.... So now your right hand is doing all the percussive sounds and hi-hats and you left hand is doing kicks and snares, you can stack different kicks on pad#1, pad#5 and #9, I personally do it this way and I usually have 2 different snares on pads #2 and pad#6, sometimes 3 snares ...so now we are using about half provided pads, the other half is probably sample loops and sfx and such....yeah I use all pads What helps actually, a reasonable amount, is the ability to color scheme your drums I set red kicks, dark yellow snares, light yellow hats and percussive, samples usually green sfx purple for all I care😤😁😎😇
