Detailed Description

A Node that plays MIDI data from a MidiMessageSequence, at a specific MIDI channel.

N.B. In order to loop correctly at changing tempos, the sequence time base must be in beats.

Member Function Documentation

getItemID()

EditItemID engine::LoopingMidiNode::getItemID

(

)

const

Returns the EditItemID to identify this Node.

getMPESourceID()

MPESourceID engine::LoopingMidiNode::getMPESourceID

(

)

const

Returns the MPESourceID used by this Node.

getActiveNoteList()

const std::shared_ptr< ActiveNoteList > & engine::LoopingMidiNode::getActiveNoteList

(

)

const

Returns the ActiveNoteList in use for this Node.

Call this after prepareToPlay to get the one in use.

setDynamicOffsetBeats()

void engine::LoopingMidiNode::setDynamicOffsetBeats ( BeatDuration  )

overridevirtual

Sets an offset to be applied to all times in this node, effectively shifting it forwards or backwards in time.

Reimplemented from engine::DynamicallyOffsettableNodeBase.

killActiveNotes()

void engine::LoopingMidiNode::killActiveNotes	(	MidiMessageArray &	,
		double	timestampForNoteOffs
	)

Iterates the ActiveNoteList adding note-off events for the active notes and then resets them.

getNodeProperties()

override

prepareToPlay()

void engine::LoopingMidiNode::prepareToPlay ( const tracktion::graph::PlaybackInitialisationInfo &  )

override

isReadyToProcess()

bool engine::LoopingMidiNode::isReadyToProcess ( )

override

process()
