@mntmn i would say that ardour (if it doesn't crash, but that improved a lot over the years?), x42-plugins and surge xt are pretty nice.

i honestly only miss minor things such as having a "real" piano roll or having the scale highlighted in the piano roll (or... whatever that thing in ardour is called). adding new tracks takes ages in ardour, that's a bit annoying. especially in huge projects.

i use melodyne and that works pretty well with yabridge.

so all in all its pretty okay tbh? don't really miss a lot
