Struct LocalControlValue

pub struct LocalControlValue { /* private fields */ }

A parameter found on most MIDI keyboards that have built-in sounds. Local Control can be set on or off, and is normally found in the global parameters for a particular instrument. When enabled the keyboard is electronically connected to the internal sounds of the instrument. This is the “normal” or default mode for most instruments. When turned off the keyboard only transmits MIDI to the MIDI out jack. The built-in sounds can then only be accessed from a MIDI input (or an internal sequencer where applicable). When people use keyboards with external sequencing equipment local control is normally turned off, and the sounds are just driven through the sequencer. This prevents a phenomenon known as MIDI echo, where a sound is triggered directly by the keyboard, and then a very short time later the same note is played again due to the data being passed through the sequencer.

Implementations

impl LocalControlValue

pub fn channel(&self) -> Channel

A getter for the channel field.

pub fn on_off(&self) -> OnOff

A getter for the on_off field.

Trait Implementations

impl Clone for LocalControlValue

fn clone(&self) -> LocalControlValue

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LocalControlValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LocalControlValue

fn default() -> LocalControlValue

Returns the “default value” for a type.

impl Hash for LocalControlValue

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for LocalControlValue

fn cmp(&self, other: &LocalControlValue) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LocalControlValue

fn eq(&self, other: &LocalControlValue) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for LocalControlValue

fn partial_cmp(&self, other: &LocalControlValue) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
