Ugritone is Finnish company, specializing to metal/punk/rock drum sampler instruments, but they have something else also. Right now they have discounts (who hasn't blackk friday discounts). I got one of their discontinued product 'Anarchy Drums' and it worked ok bidged with Airwave. In Mixbus UI worked nearly flawlessly (tab labels missing), mixer works, routing out audio with matrix works in case you want to mix different drums / mics differently.

Ok, now I ordered their 5$ offer drumkit, and that also seems to work nearly flawlessly in my linux, with Mixbus 5 getting all routed with matrix, so everything can be mixed as wanted. Tried with LinVST in Mixbus, and also with carla-single as standalone drumset.
Only flaw, tab labels at top of UI are empty.
