Control Surface main
MIDI Control Surface library for Arduino


Many bankable potentiometers and buttons. Bank selector displays bank setting using LEDs.
If any of the buttons is pressed, the LED on pin 22 is turned on.

// Create a new bank selector that changes the bank setting of the bank we just
// created.
// It has push buttons connected to pins 21 and 20 that increment or decrement
// the bank setting, and 4 LEDs to pins 46, 48, 50, 52 that display the current
// bank setting.
