Hi everyone! Forgive if this is the wrong spot for this (and I'm happy to move it), but hopefully someone can help...
Because I made so many madbean pedals (not joking - like 80%+ of my board originated here in some fashion), I needed a switcher... 9 years after starting, I'm finally finishing it up.
I just got through (with the help of the Arduino Forum) coding and breadboarding this monster 16 effect, 9-bank pedal loop/switcher. Here's a demo off the breadboard:
https://www.youtube.com/watch?v=0g-en5EuvsM (please excuse the messy practice area, hehe)
It functions great, but there's definitely some digital noise bleeding into the signal. I put the LEDs (neopixels) onto their own 5v supply, and the audio doesn't share a ground or anything with the Arduino or other 5v supply needs... but I also have no filtering on the audio signal at all. Not sure if that's what's needed, and if so, what that looks like? Would love some advice...
My next step is getting a few PCBs made for it, so I have my work cut out for me...
I'll add tap tempo, tuner and master bypass to it once I get it into the enclosure. Overall, I'm seeing a finish line, but just need to fix that pesky high pitch noise!
