I wanted to run this past everybody to see if any of you have some advice or input on this. My plan is to use arduino to interface midi to control a few motorized potentiometers and switches for an effects pedal.
The effects pedal will have 6 motorized pots and one rotary switch. The pots and switch will respond to individually assigned midi CCs. There won't be a need for internal memory for presets since I have an external midi interface that saves midi batches and sends them out according to an incoming midi PC #. So, I will be able to control the knobs externally using a midi controller and I can save a preset by simply sending the CC# corresponding to the knob position that I want.
I like the idea of motorized pots because I want to be able to use the pedal by itself without using a separate midi controller. It's also nice to see knob positions and hell... it'll look pretty cool!
I'm pretty new to the world of digital control and was wondering if any other routes are advisable before I dive in on this. Saving money isn't a concern over functionality. Is there a different route that is more reliable/consistent? Are there are certain aspects of components that work better than others (for example, faders are nicer to work with than rotary pots)? I understand that I'll want to isolate the digital power and ground from the analog pedal, but don't know how that works if the potentiometer itself is grounded to the chassis. It's a fuzz pedal so it's gonna be noisy and picky about interference.
