Legacy in the sense that it exists in the company of established DAWs such as Pro Tools, Ableton, Cubase et al.
I don't think legacy means what you think it means
Or you don't understand all of the meanings and uses of the term 'legacy'? I meant as in "legacy band"? But probably a poor choice - given there are a lot of coders here who probably associate the term with legacy systems.
Cubase is "carbon dating" levels of old. It was the thing on Atari ST's IIRC.
