selector next (up) and previous (down) PC

[santta]

Hello, does the library have selectors to switch PC up and down?
One button switches up the PC, the second button lowers the PC.

If you have a handful of programs, you can use the Program-Changer or ManyAddressesPCButton examples with an IncrementDecrementSelector.

If you want a contiguous range of program numbers, you could try something like this:

#include <Control_Surface.h>

template <setting_t NumPrograms = 128>
class FullRangeProgramChanger : public Selectable<NumPrograms> {
 public:
   FullRangeProgramChanger(MIDIAddress firstProgram = 0) : firstProgram(firstProgram) {}

   void select(setting_t setting) override {
       Control_Surface.sendPC(firstProgram + this->validateSetting(setting));
   }

 private:
   MIDIAddress firstProgram;
};

USBMIDI_Interface midi;

FullRangeProgramChanger<128> pc; // can select any of the 128 MIDI programs
IncrementDecrementSelector<128> selector {
    pc,         // this selector controls the program changer
    {2, 3},     // push button pins (increment, decrement)
    Wrap::Wrap, // Wrap around
};

void setup() {
  Control_Surface.begin();
}

void loop() {
  Control_Surface.loop();
}

thanks, I will try this sketch, and as always I will share the finished code)))
