Detailed Description

This class represents a single value for any of the MPE dimensions of control.

It supports values with 7-bit or 14-bit resolutions (corresponding to 1 or 2 MIDI bytes, respectively). It also offers helper functions to query the value in a variety of representations that can be useful in an audio or MIDI context.

Constructor & Destructor Documentation

MPEValue() [1/2]

juce::MPEValue::MPEValue ( )

Member Function Documentation

as14BitInt()

int juce::MPEValue::as14BitInt ( ) const

noexcept

Retrieves the current value as an integer between 0 and 16383.

Resolution will be lost if the value was initialised with a precision higher than 14-bit.

as7BitInt()

int juce::MPEValue::as7BitInt ( ) const

noexcept

Retrieves the current value as an integer between 0 and 127.

Information will be lost if the value was initialised with a precision higher than 7-bit.

asSignedFloat()

float juce::MPEValue::asSignedFloat ( ) const

noexcept

Retrieves the current value mapped to a float between -1.0f and 1.0f.

asUnsignedFloat()

float juce::MPEValue::asUnsignedFloat ( ) const

noexcept

Retrieves the current value mapped to a float between 0.0f and 1.0f.

centreValue()

static MPEValue juce::MPEValue::centreValue ( )

staticnoexcept

Constructs an MPEValue corresponding to the centre value.

from14BitInt()

static MPEValue juce::MPEValue::from14BitInt ( int  value )

staticnoexcept

Constructs an MPEValue from an integer between 0 and 16383 (using 14-bit precision).

from7BitInt()

static MPEValue juce::MPEValue::from7BitInt ( int  value )

staticnoexcept

Constructs an MPEValue from an integer between 0 and 127 (using 7-bit precision).

fromSignedFloat()

static MPEValue juce::MPEValue::fromSignedFloat ( float  value )

staticnoexcept

Constructs an MPEValue from a float between -1.0f and 1.0f.

fromUnsignedFloat()

static MPEValue juce::MPEValue::fromUnsignedFloat ( float  value )

staticnoexcept

Constructs an MPEValue from a float between 0.0f and 1.0f.

maxValue()

static MPEValue juce::MPEValue::maxValue ( )

staticnoexcept

Constructs an MPEValue corresponding to the maximum value.

minValue()

static MPEValue juce::MPEValue::minValue ( )

staticnoexcept

Constructs an MPEValue corresponding to the minimum value.

operator!=()

bool juce::MPEValue::operator!= ( const MPEValue &  other ) const

noexcept

Returns true if two values are not equal.

operator==()

bool juce::MPEValue::operator== ( const MPEValue &  other ) const

noexcept

Returns true if two values are equal.
