Yabridge exist for windows plugins. Surprisingly works pretty good. My arturia pack works w/o any major issues. There is some virtual monitor thingy I do on sway to workaround weird performance bug. But I don’t think it should surface on kde for example.
As for Reaper, DAWs and Linux: Make sure to have low latency setup for pipewire. I had to configure some stuff on arch and add pipewire latency variable with lowest values that my interface can handle to launch option for reaper. I prefer playing and practicing on Linux over the windows in terms of latency now. For how messy pipewire can be, when it’s setup correctly, it’s magnitudes better than windows for low latency audio not just because of latency, but because of current windows audio drivers limitations. I no longer record or edit for quiet some time, so can’t say how it compares to other DAWs. Also why I’m personally using reaper: it’s intuitive, fast, fair price, good terms (perpetual license with updates, there is eol for updates, but it’s focused on specific version release, and for how release cycle goes it can last almost a decade, and you can still use the older versions after update eol, but better read terms yourself), and It has trial period over which I decided that it’s best suited for me.
https://wiki.archlinux.org/title/Professional_audio https://wiki.archlinux.org/title/PipeWire I had some stuff on arch not working from the box, and interface selecting wrong type, which added latency as well. I managed to debug most of my stuff using those 2 pages and pipewire documentation. You may not need most of it on another distro. But it’s a good read either way. I changed way too much and long time ago to remember everything though. If everything setup correctly, setting lowest interface supported values for pipewire latency should do the trick (point 3.1.3 on pipewire arch wiki page), without it pipewire will default to the default config option, hence why you probably felt the delay.
