FlexASIO VS Camomile

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

Camomile is (still) the only thing that will do what you want. https://github.com/pierreguillot/Camomile

I think the first project of this kind was pdvst~ (https://github.com/jyg/PdVst). A more recent effort is Camomile (https://github.com/pierreguillot/Camomile).

PlugData seems to be much more extensive and flexible, though!

You can compile to vst with camomile as well, I wanted to mention.

I have a different suggestion

you should definitely check Camomile by Pierre Guillot, i managed to run relatively complex patches as audio plugins through it on several DAWs just fine, with midi mapping and preset saving capabilities, however when running my synths as instrument plugins i found a couple of inconsistencies that made them kind of unreliable... i hope it gets better with future updates, if i ever get good at c++ i'd like to help with its development because it truly is an amazing work

There is a project called camomile where you can run a Pd patch as a VST with built in support for building a GUI within the patch and integration with basic DAW stuff like BPM sync.

Camomile - fairly easy way to get Pure Data patches in plugin form; incredible rabbit hole to potentially fall down if you want total control
