#include <MIDI_Outputs/Bankable/NoteButtonMatrix.hpp>
A class of MIDIOutputElements 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.
NumRows | The number of rows of the matrix. |
NumCols | The number of columns of the matrix. |

Create a new Bankable NoteButtonMatrix object with the given pins, note numbers and channel.
config | The bank configuration to use: the bank to add this element to, and whether to change the address, channel or cable number. |
rowPins | A list of pin numbers connected to the rows of the button matrix. ⚠ These pins will be driven LOW as outputs (Lo-Z). |
colPins | A list of pin numbers connected to the columns of the button matrix. These pins will be used as inputs (Hi-Z), and the internal pull-up resistor will be enabled. |
notes | A 2-dimensional array of the same dimensions as the button matrix that contains the note number of each button. [0, 127] |
channelCN | The MIDI channel [Channel_1, Channel_16] and Cable Number [Cable_1, Cable_16]. |
velocity | The velocity of the MIDI Note events. |
