Motorized faders are somewhat common (https://www.sweetwater.com/store/search.php?s=motorized+faders) but perhaps more expensive than I would have guessed. But motorized knobs are nowhere to be found on MIDI controllers and DAW console controllers for switching/restoring presets/banks. Instead, manufacturers go with LED rings around encoders, which unfortunately require your eyes to check if the knob is at one of its extremes.
What’s the reason for the empty market? Motorized pots exist on Mouser for around $10/ea, so an 8-knob controller would cost $80 plus probably $60 of other parts and would be sold at probably $400-500. But I can’t find any products that do this. You could theoretically control your entire DAW or VCV Rack with thousands of parameters by sorting them into “banks” that could be selected with an up/down button on the controller. If you select “VCV Mixer” for example, the first 5 knobs could immediately rotate to their current positions and be updated by manually adjusting the knobs, until another module is selected.
