Ableton is great and paved the way for a more creative and intuitive workflow! I switched from Cubase very early on and never looked back. That is, until I found Bitwig (https://www.bitwig.com) which supports Linux! They also deserve a shout out taking it even further!
Bitwig looks really promising. But how is the VST landscape? Is it even supported?
EDIT: sorry, my question was about whether Linux supports VST. I would assume that Bitwig did at v0.1 :-)
I don't remember how well it integrated with Bitwig - but a few years ago VST support on Linux using Wine, Jack and Carla (https://github.com/falkTX/Carla) was pretty solid.
