How to use buttons and send Midi CC and Midi Note through multiplexer? about control-surface

[tttapa]

The principle is the same for all MIDI elements, you just pass them a pin number.
If the pin is a real Arduino pin, the pin number will be 2 or A0 etc. If it's not a real Arduino pin, you get the pin number from the ExtIO device you're using, e.g. mux.pin(0).

See this example: https://tttapa.github.io/Control-Surface/Doc/Doxygen/d8/d59/1_8First-Output_8ino-example.html.
And adapt it to use CCButton instead of CCPotentiometer.

If you specify pin 2 as the first argument to the CD74HC4067 constructor, then it expects the signal pin to be connected to pin 2.

I have downloaded your library again. I opened the sketch "First-Output" when I check it for errors I've got an error:

Why it tells me about file with Led if I even didn't use any leds?

I have also checked the code from your link, same error appears

Ah, I see, my bad, I added a dependency on the FastLED library, and it seems like I try including it even when it's not installed.

I'll fix it in a moment.

Please, leave a message when you fix it. Thanx!

In the meantime, you can just install the FastLED library using the library manager, and it should work again.

Yes, it works. Just leave a message when you fix this bug. I always want to have new version of library without any bugs:)

[tttapa]

It should work now.

It worx, thank you!
