MIDI Output Elements

Original: MIDI output elements

Output elements read physical controls and send MIDI messages. They register with Control_Surface on construction and update automatically in the loop() cycle.

Buttons

Class	Description	Constructor
`NoteButton`	Note On/Off on press/release	`{pin, address}`
`CCButton`	CC 127/0 on press/release	`{pin, address}`
`PCButton`	Program Change on press	`{pin, address}`
`NoteButtonLatched`	Toggle Note each press	`{pin, address}`
`NoteButtonLatching`	Note while held, toggles	`{pin, address}`
`CCButtonLatched`	Toggle CC each press	`{pin, address}`
`CCButtonLatching`	CC while held, toggles	`{pin, address}`
`NoteChordButton`	Multiple notes on press	`{pin, address, chord}`

Button arrays and matrices

Class	Description
`NoteButtons<N>`	Array of N sequential note buttons
`CCButtons<N>`	Array of N sequential CC buttons
`NoteButtonMatrix<R,C>`	Row/column scanned note grid
`CCButtonMatrix<R,C>`	Row/column scanned CC grid

Potentiometers

Class	Description
`CCPotentiometer`	Analog input → CC 0-127
`PBPotentiometer`	Analog input → 14-bit Pitch Bend
`CCPotentiometer` with `map()`	Custom mapping to calibrate or apply curves

CCPotentiometer pot {26, {MIDI_CC::Channel_Volume, Channel_1}};
pot.map(myMappingFunction);

Encoders

Class	Description
`CCRotaryEncoder`	Relative CC from quadrature encoder
`CCAbsoluteEncoder`	Absolute CC position from encoder
`PBAbsoluteEncoder`	14-bit Pitch Bend from encoder
`BorrowedCCRotaryEncoder`	Shared encoder reference
`CCIncrementDecrementButtons`	Two buttons for CC inc/dec

CCRotaryEncoder enc {{0, 1}, {MIDI_CC::Pan, Channel_1}, 1, 4};

Constructor: {pin_pair, address, speed_multiplier, pulses_per_click}.

Program changers

Class	Description
`ProgramChanger<N>`	Selectable list of N program changes

ProgramChanger<4> pc {{
    {MIDI_PC::Harpsichord, Channel_1},
    {MIDI_PC::Organ, Channel_1},
    {MIDI_PC::Guitar, Channel_1},
    {MIDI_PC::Piano, Channel_1},
}};
