I switched to Bitwig, which has a native version for Linux. The workflow is very similar to Ableton Live, with a little bit of extra configuration. As for gaming, it's a case-by-case situation, but Valve Proton is good enough for 80% of the games I like.

Yeah I've heard that Bitwig could be a good solution, and is made by the original developers of Ableton.

But what about 3rd party plugins? As far as I understand, most of these won't work on Linux either.
