#include <MIDI_Outputs/ManyAddresses/NoteButtonMatrix.hpp>

Detailed Description

template<setting_t NumBanks, uint8_t NumRows, uint8_t NumCols>
class Bankable::ManyAddresses::NoteButtonMatrix< NumBanks, NumRows, NumCols >

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 using an arbitrary list of alternative addresses.

Template Parameters

NumBanks	The number of variants/alternative addresses the element has.
NumRows	The number of rows of the matrix.
NumCols	The number of columns of the matrix.

		const PinList< NumRows > &	rowPins,
		const PinList< NumCols > &	colPins,
		const Array< AddressMatrix< NumRows, NumCols >, NumBanks > &	notes,

	)

inline

Create a new Bankable NoteButtonMatrix object with the given pins, controller numbers and channel.

Parameters

bank	The bank to add this element to.
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 list of 2-dimensional arrays of the same dimensions as the button matrix that contains the MIDI Note number of each button. [0, 127]
channelCNs	The a list containing the MIDI channels [CHANNEL_1, CHANNEL_16] and Cable Numbers [CABLE_1, CABLE_16].
velocity	The velocity of the MIDI Note events.
