@Legonatic@birdcannon - you might want to take a close look at Bitwig. It's a top-notch DAW developed by former Ableton developers. I hear it's fairly similar workflow to Ableton, but also that it's better in certain ways. This is without even taking into consideration that Bitwig supports Linux. I don't have any association with Bitwig, don't even own it (yet?), but just wanted to let you know.
I think I've heard that some VST support may be tricky though. I could be misremembering, but also worth researching.
