Sweet! 

It's really great to hear that this has been of use to someone.

 

How are you finding the looper controls? I've never had much luck with mine and I'm not sure whether it's down to my lack of foot coordination, or the cheap footswitches I used, or lag in the code. I keep meaning to adapt the code to use pin change interrupts for button press detection, but I've got another project I want to get out of the way first before coming back to this one....

The looper controls work fine, I'm using de Bouncer2 library to detect button press with very short interval and BOUNCE_WITH_PROMPT_DETECTION  option to detect it immediately, it would be faster using the press event  but I'm using the release event to avoid firing a message when long press or double press is used although I may change it to press just to test. One recommendation is to not use the sleep function, this is important to make it more responsive.

I just want to say thank you very much to @stoo, I have just build my own midi controller for my HX Stomp based on your code and wanted to show the result. I used different board, layout and libraries but it all started with your post.

I have attached my code but I would try to keep it update on github: https://github.com/yeraym/vulcano_controller
