I thought renoise has a linux version that works, but you might have issues getting all vst's to work properly. there are compatibility programs like carla that should help.

you can get fl studio running with wine/bottles but it would be better if there were native versions.

Compatibility layers always make things a little unstable. With proton it's gotten significantly better, but that doesn't always translate to audio apps. The only way to know if it will work is to set everything up and test it.

If you ever tried to mess with audio on linux in the past, it's gotten a whole lot easier with pipewire. There are very few config issues now.
