 * @brief   A class of MIDIOutputElement%s that read the input from a **matrix
 *          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.  
 * Crude software debouncing is implemented by limiting the refresh rate.  
 * This version can be banked using an arbitrary list of alternative
 * addresses.
 *          
 * @tparam  NumBanks
 *          The number of variants/alternative addresses the element has.
 * @tparam  nb_rows
 *          The number of rows of the matrix.
 * @tparam  nb_cols
 *          The number of columns of the matrix.

     * @param   config
     *          The bank configuration to use: the bank to add this element to,
     *          and whether to change the address, channel or cable number.
     * @param   rowPins
     *          A list of pin numbers connected to the rows of the button
     *          matrix.  
     *          **⚠** These pins will be driven LOW as outputs (Lo-Z).

     *          internal pull-up resistor will be enabled.
     * @param   notes
     *          A list of 2-dimensional arrays of the same dimensions as the 
     *          button matrix that contains the MIDI Note number of each button.
     *          [0, 127]
     * @param   channelCNs
     *          The a list containing the MIDI channels [CHANNEL_1, CHANNEL_16] 
     *          and Cable Numbers [0, 15].
     * @param   velocity
     *          The velocity of the MIDI Note events.
