Hi there!
Just a quick one,
I was wondering is it possible to add MIDI functionality (preset recall, storage, bypass etc) to a digital guitar pedal using the arduino uno?
I’ve had this idea of taking budget pedals such as a digital delay or reverb and adding MIDI functionality in order to place them in a guitar gig rig using a “master” MIDI controller.
Any help on this would be deeply appreciated folks!!
Hello
I hope these links help you
@chrisneedsmoremidi, your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advise on) your project

Hi and welcome to the (right) forum.
Post a link to one or two of the f/x pedals you are talking about.
This should be easy, but what exact you need to do depends on how you go about hijacking the existing controls.
Are you cool with forgoing the future use )or at least simultaneous( use of the existing control means?
Or wouldn't it be nice to have your improvement kinda sit between the existing controls, so you use them, and listen to said use, then control the actual circuitry doing the effect?
Either way, once you are in control by Arduino of the effect circuitry, the MIDI will be conceptually straightforward and not too bad code wise I think.

Hey there a7,
Thankyou for the warm welcome,
These are the pedals I'm wishing to add midi functionality too:

I'm hoping to be able to make it so they still have all their original functionality but with the added ability to save/recall presets by themselves (as individual pedals) and via the use of a "master controller" (a boss switching system as an example) so I can switch patches.
I'm very much new to the Arduino and definitely a novice at coding. I have downloaded the Arduino software and MIDI libraries but just have no idea where to start with this one....
All your help would be appreciated.

OK, noobs are tots welcome around these parts.
Do you have any knowledge/experience with basic electronics? Soldering? Do you have a multimeter of any stripe?
The more yes answers the better, but everyone started at zero and with motivation and time you have a reasonable goal.
It’s not going to be instant or without some hair tearing and work, so just relax and take it very step by step.
The IDE has example code starting from near zero, you could start just reading and playing with that, always squint and pretend like you know what you ar doing and you will see patterns emerge.
Kinda like going to a foreign country and hanging out in a a cafe.

OK, I took a peek at the three example units.
I haven’t been in and out of anything exactly like that, but given the size (small) and price (low) it is very likely that the switching and potentiometers are very closely integrated with a surface mount components PCB.
Not impossible, but the bar is def very higher than it might have been in the old days. Of course back in the day there was no MIDI or readily available and easy to use microprocessors, so while one hand has given, another has taken away.
If you have any of those, open one right the f up and take a few snaps and post them here. Two or three pictures showing as much as you can of how the mechanical concept is executed.
And I must ask, are you prepared to go a long way, ruin a perfectly good stomp and fail?
Just trying to manage expectations here, I can be pessimistic but I think here I am being realistic.
