Member Function Documentation

void CFugue::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

Definition at line 107 of file MidiEventManager.h.

References GetTrackTime().

void CFugue::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

Definition at line 120 of file MidiEventManager.h.

References GetTrackTime().

void CFugue::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

Definition at line 133 of file MidiEventManager.h.

References GetTrackTime().

void CFugue::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;

Definition at line 202 of file MidiEventManager.h.

void CFugue::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

Definition at line 146 of file MidiEventManager.h.

void CFugue::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
