/**
 * @brief   A class of MIDIOutputElement%s that read the input of a **collection 
 *          of momentary push buttons or switches**, and send out MIDI **Note** 
 *          events.
 * 
 * A Note On event is sent when a button is pressed, and a Note Off event is
 * sent when a button is released.  
 * The buttons are debounced in software.  
 * This version cannot be banked.
 * 
 * @tparam  NUMBER_OF_BUTTONS
 *          The number of buttons in the collection.

     * @param   buttons
     *          An list of digital input pins with the buttons connected.  
     *          The internal pull-up resistors will be enabled.
     * @param   baseAddress
     *          The MIDI address of the first button, containing the note
     *          number [0, 127], channel [CHANNEL_1, CHANNEL_16], and optional 
     *          cable number [0, 15].
     * @param   incrementAddress
     *          The number of addresses to increment for each next button.  
     *          E.g. if `baseAddress` is 8, and `incrementAddress` is 2,
     *          then the first button will send on address 8, the second
     *          button will send on address 10, button three on address 12, etc.
     * @param   velocity
     *          The velocity of the MIDI Note events.
