Almost 4 years since the original post and still not 1 Arturia device listed in Studio One. The above screenshot is taken from Logic Pro 10.7.5. I have to say having used Studio One as my main DAW for 8 years (currently own Studio One 6), bought ERIS Speakers, Atom SQ controller (both returned due to quality issues) made multiple movie soundtracks, released an EP. I think I may have to move back to Logic Pro to release my upcoming Album.
Given there is no indication or updates of where Fender will take Studio One next it feels like the community has been forgotten. I can understand why the owners sold it. It is a shame as it has so much potential.
