No problem,
Any midi controller that works with a protocol that CB supports will do what you want (control your vst parameters). I would characterize the controller I suggested (Korg nanoKONTROL2) as a inexpensive way to get into these things.
There are much more expensive ones available that have many more knobs/sliders/switches, etc. that, of course control more parameters. These more expensive ones also “look” like they fit in a professional studio setting which by itself could be very important to those who need/want to impress their customers/talent.
All in all the Korg nanoKONTOL2 I have works fine for me and it serves the purpose I need it for.
Again, have fun searching for and finding the one you want.
