The obvious one is Steinberg cc121.
Outside of that I think you’d be picking between two control protocols, Mackie MCU and Eucon. There are benefits and drawbacks to both.
MCU products are cheaper but in terms of automation if I recall correctly there’s still a slight lag after you release (stop “touch”) the fader before it returns to reading automation. It may be a bummer, it might not.
Eucon is probably the better of the two, but the one thing people have talked about is if the show/hide tracks is reflected on the controller I think now it isn’t. There’s an update coming soon-ish and maybe that’ll be fixed there. Eucon devices are generally higher quality people tend to feel, in general.
