I could imagine it's hard to find something who will match the flow of your hardware.
I don't know if you have already checked out these linux native options:
Speedrum - https://www.apisonic-audio.com/speedrum2.html
Or
Atlas 2 - https://algonaut.audio/
I have always just used Drum Rack or another DAW software sampler, so I'm not sure what the difference would be if it's hardware specific.
