Calling a custom function from a button press in a mux

[MoSaye]

Hello there,

Is there a way to call a function when a single button is pressed, the button is connected in a mux, so what i want to do is to call a custom function when this specific button is pressed and sends a midi note on

Thanks for your help and great work

so for example this is the mux code:

NoteButton LimitSwitches[] = {
{mux3.pin(0), {note:0x00, CHANNEL_1}},
{mux3.pin(1), {note:0x01, CHANNEL_1}},
{mux3.pin(2), {note:0x02, CHANNEL_1}},
{mux3.pin(3), {note:0x03, CHANNEL_1}},
{mux3.pin(4), {note:0x04, CHANNEL_1}},
..........

I want to call a function called x for example when the first button is pressed, or the third button, just a specific button in the mux array

You can get the button state from the NoteButtons:

if (LimitSwitches[i].getButtonState() == Button::Falling)
  someFunction();

If you need more flexibility, see this example: https://tttapa.github.io/Control-Surface-doc/Doxygen/d4/d3b/Custom-MIDI-Output-Element_8ino-example.html

Thank you for the explanation, getting the button state works fine and i will look into the custom midi output for more.
