Detailed Description

A tempo value, as used in a TempoSequence.

This specifies the BPM, time sig, etc. at a particular time

Member Typedef Documentation

◆ Ptr

using tracktion::engine::TempoSetting::Ptr = juce::ReferenceCountedObjectPtr<TempoSetting>

Constructor & Destructor Documentation

◆ TempoSetting()

tracktion::engine::TempoSetting::TempoSetting	(	TempoSequence &	,
		const juce::ValueTree &
	)

Constructs a TempoSetting belonging to a given TempoSequence.

Don't construct these directly, use the appropriate insert methods of TempoSequence.

◆ ~TempoSetting()

tracktion::engine::TempoSetting::~TempoSetting ( )

override

Destructor.

Member Function Documentation

◆ getEdit()

Edit& tracktion::engine::TempoSetting::getEdit ( ) const

Returns the Edit this setting belongs to.

◆ create()

static juce::ValueTree tracktion::engine::TempoSetting::create	(	BeatPosition	startBeat,
		double	bpm,
		float	curve
	)

static

Creates a tree to prepresent a TempoSetting.

◆ getSelectableDescription()

juce::String tracktion::engine::TempoSetting::getSelectableDescription ( )

overridevirtual

Returns the description of this Selectable.

Implements tracktion::engine::Selectable.

◆ getStartBeat()

BeatPosition tracktion::engine::TempoSetting::getStartBeat ( ) const

Returns the start beat of the setting.

References startBeatNumber.

◆ getBpm()

double tracktion::engine::TempoSetting::getBpm ( ) const

Returns the BPM of the setting.

References bpm.

◆ getCurve()

float tracktion::engine::TempoSetting::getCurve ( ) const

Returns the curve of the setting.

References curve.

◆ getStartTime()

TimePosition tracktion::engine::TempoSetting::getStartTime ( ) const

Returns the start time in seconds of the tempo setting.

◆ set()

void tracktion::engine::TempoSetting::set	(	BeatPosition	,
		double	newBpm,
		float	newCurve,
		bool	remapEditPositions
	)

Sets the properties of this tempo setting.

Parameters

startBeatNum	The new start beat number to set.
newBpm	The new bpm value to set.
newCurve	The new curve to set.
remapEditPositions	If true, this will adjust any Edit items start/end positions so they fall on the same beat as they currently do.

◆ setBpm()

void tracktion::engine::TempoSetting::setBpm ( double newBpm )

Sets the BPM of this tempo setting.

◆ setCurve()

void tracktion::engine::TempoSetting::setCurve ( float curve )

Sets the curve of this tempo setting.

<0.0 is a log curve 0.0 is a linear curve >0.0 is an exponential curve

◆ setStartBeat()

void tracktion::engine::TempoSetting::setStartBeat ( BeatPosition )

◆ removeFromEdit()

void tracktion::engine::TempoSetting::removeFromEdit ( )

Removes the TempoSetting from the sequence.

◆ getApproxBeatLength()

TimeDuration tracktion::engine::TempoSetting::getApproxBeatLength ( ) const

Returns the approximate length of one beat based on the bpm and matching time sig denonimator.

◆ getPreviousTempo()

TempoSetting* tracktion::engine::TempoSetting::getPreviousTempo ( ) const

Returns the previous tempo setting in the sequence.

◆ getMatchingTimeSig()

TimeSigSetting& tracktion::engine::TempoSetting::getMatchingTimeSig ( ) const

Returns the time signature at this tempo's time in the sequence.

◆ getHash()

HashCode tracktion::engine::TempoSetting::getHash ( ) const

noexcept
