Hay nmuturi,
Did you ever get this to work. I am trying to do the same thing but with El Wire. I tool you code that you had posted. (Hope that’s ok) and modified it a bit.
I got it to work. Well I got sound and things light up that is. But not the way I would like to. Right now it’s light up a different El wire per tone not note.
If you worked it out can you post the code.
I am working on it but, I just started playing with Arduion a few days ago and I am just learning the code.
Thanks
