It’s not worth the headache to try to get it working. Look at more modern devices that are fully supported and up to date.
Unfortunately, Native Instruments fubared the Traktor Audio 2 hardware pretty good and never went back to support it or much of anything else after the company got driven into a ditch (pre and post COVID). Don’t get me wrong, I want NI/Traktor to succeed, I actually have a current subscription, but their actions are pretty stark / Game of Thrones and don’t hold much promise for the future.
NOTES:
My Audio 2 worked fine when I first bought it, but iOS eventually moved forward and stopped supporting whatever class compliance it had. It first stopped working on the iPhone (even though it was working fine before), then iPad OS became glitchy and stopped working - eventually it was only reliable on macOS or other laptops.
One other thing negative, its under-powered for the larger battery draw of the 12" iPad Pros.
I chucked mine in the garbage and I was glad to move on to better supported hardware.
