Arduino not speaking to EOS

Did you activated "OSC USB" in Setup > System Setting > Show Control > OSC ?

Thank you!! I am sorry to bother but I still not understadning alot of this. I got the two buttons to work but now i want to make the 3rd button a macro button which would be AT FULL REMDIM. I am confused on how to change the buttons function in the code itself.

Maybe you have a look to my library https://github.com/sstaub/eOS

Ive looked through that but I don’t know exactly what im looking for. I think im looking for a list of the buttons i can use for it. from my understanding the next and last buttons are just apart of some list of options of buttons that are available to be used with this library.

My library allows to use the encoder buttons (if there are) as shift button. There is macro button method and example.
