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

`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}`

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

`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
