switching programs on two buttons

[Wallirec]

Hello! Tell me how to switch programs on two buttons, I can’t find an example. The first button increases the program number and the second decreases it.

The following resources should help:

• FAQ: Can I change the address, controller number, MIDI channel, etc. at runtime?
• Bank.ino
• PCButton
• ManyAddressesPCButton.ino
• IncrementDecrementSelector

Yes, thanks, I found all these links myself. There is switching banks, binding the program number to the button ... But I did not find (not enough knowledge) how to switch programs with two buttons. My midi keyboard has no control buttons and I need to switch programs in the Raspberry sampler.
