BSP Drum section with more than 16 pads?

[KumoNekko]

Hi all,

Today I finally decided to use my Roland JD XI instead of my Korg Volca Beats.
But I met a problem. The drum section on the Roland JD XI keyboard is bigger than 2 octaves, and the 16 pads of the BSP pro are not enough.

Is there any way to overcome this problem? And by overcome this problem, I mean, is there a proper solution to this issue?

Thanks a lot.
