To be honest, any midi foot controller would work. Obviously there are many options and price points, and people seem to prefer some of the fancy ones (like the Morningstar MC8), but I’ve seen a lot of people mentioning Boss FCB1010 and also the Line 6 FBV Express USB MKII / FBV-3. There are some alternative options like Fractal Audio MFC-101 , Blackstar Live Logic Midi , Xsonic Airstep Smart MIDI Controller , Logidy UMI3, Hotone Ampero Control Midi and finally the cheapest option I know of, which would be the M-Vave Chocolate Wireless Midi Controller (this is the one I own now and have been using for the past few months, and so far no issues, except with Plini X - but Neural seems to be investigating the issue, and it’s probably because to the plugin update).
If you need expression pedal, I known the Boss and Line 6 options already include that. For wireless, I am only sure about the cheap M-Vave and the Hotone, and I think the Airstep has that option as well.
I guess there must be a lot of posts around here on the community discussing midi controllers in all sorts of scenarios, which might provide some helpful insight as well.
Anyway, good luck!
