Awesome list, I’ll definitely be checking these out. Do you have any favourites?
It’s been a while since I didn’t have time to do serious audio work on Linux :/ But I used to use a mix of audacity, calf-plugins, ardour, tal-plugins, mixxx, drumkv1, hydrogen, synthv1, VCV rack, samplv1. I did a bit of lighting with QLC+, very basic video editing with Openshot. Got briefly into Blender and loved it. Plus a bunch of utilities (qwinff, jack-related stuff, I did never find a proper way to save/restore sessions/plugins/patchbays though), and media players (currently use quodlibet/vlc/mpv).
I want to get into Bitwig since I’m a former Ableton Live user, but the license is sooooo expensive.
You can dip in with the essentials package for €80 though (perhaps even this is the type of thing they bundle with stuff so you might find a free licence key for it somewhere). They might also offer a crossgrade price if you contact them. I got a great crossgrade offer from Presonus when I decided to start using Studio One. I just had to prove my ownership of another DAW (I sent them a Reason 10 receipt I think).
