Member Function Documentation

void MusicNoteLib::MIDIEventManager::AddChannelPressureEvent

(

unsigned char

uPressure

)

Adds a Channel Pressure event to the current track

Parameters:

uPressure

the pressure value that should be applied to the notes on the current channel

References GetTrackTime().

void MusicNoteLib::MIDIEventManager::AddControllerEvent	(	unsigned char	uControlIndex,
		unsigned char	uControlValue
	)

Adds a MIDI controller event to the current track.

Parameters:

uControlIndex	the controller
uControlValue	value for the controller

References GetTrackTime().

void MusicNoteLib::MIDIEventManager::AddKeySignatureEvent	(	signed char	nKeySig,
		unsigned char	MajMin
	)

Adds a short Key Singature event to the current track.

Parameters:

nKeySig	a value in the range [-7, 7]
MajMin	indicates if this is Major (0) scale or Min (1) scale

References GetTrackTime().

void MusicNoteLib::MIDIEventManager::AddNoteEvent	(	int	noteValue,
		int	attackVel,
		int	decayVel,
		long	lNoteDuration,
		bool	addNoteOn,
		bool	addNoteOff
	)

Adds a short NoteOn message event to the current track using attack/decay velocities. Automatically adds a NoteOff message using the specified duration. These NoteOn and NoteOff can be suppressed (useful when notes are tied).

Parameters:

noteValue	the MIDI note value. For example, Mid-C = 60
attackVel	the attack Velocity of the note
decayVel	the decay Velocity of the note
lNoteDuration	duration of the MIDI note
addNoteOn	indicates if NoteOn event should be created automatically. For the end of a tied note, this should be false; otherwise true;
addNoteOff	indicates if NoteOff event should be created automatically. For the start of a tied note, this should be false; otherwise true;

References AdvanceTrackTime(), and GetTrackTime().

void MusicNoteLib::MIDIEventManager::AddPitchBendEvent	(	unsigned char	uLowByte,
		unsigned char	uHighByte
	)

Adds a PitchBend event to the current track.

Parameters:

uLowByte	the low byte value of the pitch bend
uHighByte	the high byte value of the pitch bend

References GetTrackTime().

void MusicNoteLib::MIDIEventManager::AddPolyphonicPressureEvent	(	unsigned char	uKey,
		unsigned char	uPressure
	)

Adds a key pressure event to the current track.

Parameters:

uKey	the note the pressure should be applied to
uPressure	the Pressure value that should be applied to the key

References GetTrackTime().

void MusicNoteLib::MIDIEventManager::AddProgramChangeEvent

(

unsigned char

nInstrumentID

)

Adds a short ProgramChange message event to the current track.

Parameters:

nInstrumentID

indicates the selected instrument that should be used for playing further notes;

References GetTrackTime().

void MusicNoteLib::MIDIEventManager::AddTempoEvent

(

unsigned short

nTempo

)

Adds a short Tempo message event to the current track.

Parameters:

nTempo

indicates the selected Tempo value in BPM that should be used for playing further notes;

References GetTrackTime().

void MusicNoteLib::MIDIEventManager::AdvanceTrackTime

(

unsigned long

lDuration

)

Advances the timer for the current Track by the duration (specified in Pulses Per Quarter)

Referenced by AddNoteEvent().

void MusicNoteLib::MIDIEventManager::Clear

(

)

Clears all the Events stored in the tracks and Resets the Track Timers

Reimplemented in MusicNoteLib::MIDIRenderer.

unsigned long MusicNoteLib::MIDIEventManager::GetTrackTime

(

)

const

Returns the Timer value for the current track (in Pulses Per Quarter)

Referenced by AddChannelPressureEvent(), AddControllerEvent(), AddKeySignatureEvent(), AddNoteEvent(), AddPitchBendEvent(), AddPolyphonicPressureEvent(), AddProgramChangeEvent(), and AddTempoEvent().

void MusicNoteLib::MIDIEventManager::SetCurrentTrack

(

unsigned short

nTrack

)

Sets the current Track/Channel to which new Events will be added

void MusicNoteLib::MIDIEventManager::SetTrackTime

(

unsigned long

lNewTime

)

Sets the current Track's time to the supplied new time (specified in Pulses Per Quarter)
