How can I change button's note with master button? about control-surface HOT 9 CLOSED

Changing noteNames doesn't change the addresses of the buttons.

I think what you need is the ManyAddresses::NoteButton.
That's the best way to do it if you need arbitrary addresses.

If you just want to transpose everything by the same amount of semitones, it's best to use the Bankable::NoteButton class combined with a Transposer.

Can you show me some examples of ManyAddresses::NoteButton?

In addition, Is it possible to make when you press button 1, you increase one octave, when you press button 2, you go one octave down, when you press button 3, you can change the major order (F-C-G-D-A-E-B to Gb-Db-Ab-Eb-Bb-Fb-C), when the button 4 is pressed, return the majors in order?
(sorry this is translated comment, so it can be strange.)

Sure, basically, you create a custom class that has a lock, unlock and getActiveAddress method.

Lock and unlock ensure that the note number doesn't change while the button is pressed (otherwise the note off event will be sent to a different address, leaving the original note playing forever).

GetActiveAddress returns the right address, in your case, the address of the right note (F or Gb) plus or minus one octave.

ManyAddresses is a class that handles a list of alternative addresses, and BankableMIDIOutput is a class that adds an offset to a given address, so both are combined:

Then you just pass it as the first template argument to the Bankable::MIDIButton class.

It looks scary, but it's all just glue between existing classes. You probably don't have to change that file.

What you do have to change is the note numbers etc. in the main sketch:

That looks really nice, I'll try it.
I really love you and this library!

Oh, by the way, if you're not seeing any MIDI output, that could be because the sketch uses a USBDebugMIDI_Interface, it prints the MIDI message in a readable format to the serial monitor. You can change it to a USBMIDI_Interface if you want.

Can I ask one more question?
When there is a Bank , is it possible to press the button to go to the last bank and press the button again to return to the previous bank?

from control-surface.

Not sure what you mean.

The Bank class has a select method that you can call directly: https://tttapa.github.io/Control-Surface/Doc/Doxygen/db/dbd/classBank.html#ab4b91b7f4363e5e497b34e17a303bdbb

There are some included Selectors that can manage a Bank, based on the input from push buttons or rotary encoders etc. https://tttapa.github.io/Control-Surface/Doc/Doxygen/d0/d0c/group__Selectors.html

It works very nice, thanks!
