CCIncrementDecrementButtons
This is an example that demonstrates the use of Increment and Decrement buttons that can be used for scrolling through a song list, tuning effects, etc.
You can compare it to a rotary encoder, but with two buttons instead of an encoder.
- Boards:
- AVR, AVR USB, Nano Every, Due, Nano 33 IoT, Nano 33 BLE, Pi Pico, Teensy 3.x, ESP32, ESP8266
Connections
- 5: momentary push button (to ground)
- 6: momentary push button (to ground)
The internal pull-up resistors for the buttons will be enabled automatically.
Behavior
- If the button on pin 5 is pressed, a MIDI CC increment message is sent.
- If the button on pin 6 is pressed, a MIDI CC decrement message is sent.
- The controller number
MCU::V_POT_1
will be used.
- If either of the buttons is pressed down for a longer time, it will keep on sending increment/decrement messages quickly until you release it (like a key on a computer keyboard). This is to make it easier to scroll a large amount, for example. The timing can be changed by tweaking AH::LONG_PRESS_DELAY and AH::LONG_PRESS_REPEAT_DELAY in AH/Settings/Settings.hpp.
- If both buttons are pressed simultaneously, a MIDI Note On event is sent on note
MCU::V_POT_SELECT_1
.
(This is optional, you can just leave out the final argument to the constructor, and it won't send anything when you press both buttons at once).
- The multiplier can be used to increment multiple ticks per each time you press a button. This is useful if you have to press the button for a very long time to get a substantial change.
Map the Arduino as a Mackie Control Universal (MCU) or equivalent in your audio software.
