I had a similar issue with my setup, I suggest using FLEXASIO. Youll need to download flexasio and the gui component to use it. https://github.com/dechamps/FlexASIO

The problem I have with FlexASIO is that it only supports having 1 input while the katana requires multiple. See: https://github.com/dechamps/FlexASIO/issues/147

The UMC-22 has a budget Midas-type pre-amp which is hard to beat under $200. That said, the UMC-22 also has terrible ASIO4ALL based drivers which can partially be worked around by using something like FlexASIO. Ultimately though, the drivers won't matter unless you are using heavier VST plugins for your voice/audio input.

FlexASIO allows none exclusive mode but it does it in a different way to regular ASIO drivers. You will have to give it a try to see if it can provide a latency that is acceptable. It is meant to work with more hardware than regular ASIO drivers. I suspect that latency might be compromised somewhat but give it a try to see if it works okay for you. It does explain how it works compared to other ASIO drivers on the github page.

FlexASIO is the modern and IMO better alternative to ASIO4ALL, just sayin.

You could try https://github.com/dechamps/FlexASIO It's a universal asio driver that allows non-exclusive mode
