I am not sure it is programmed to respond to bellows pressure on the Korg, but no it is not possible on the 8X, but as Ventura mentioned, it would not be as versatile as having it velocity sensitive. This is easy and something that I use a lot, it is like having separate control of the drums, bass, right hand percussive instruments and accordion all separately.
One thing that the 8X can do that the Korg cannot… map drum sounds to the right hand. Now it’s not something that I use a lot but I do use it in a couple songs, it’s fun.
