Detailed Description

Auxiliary class for microtonal conversion.

Definition at line 36 of file midimicrotonalhelper.h.

Constructor & Destructor Documentation

MidiMicrotonalHelper::MidiMicrotonalHelper ( MidiMicrotonal * midimicrotone )

Constructor, resetting the member variables.

Parameters

midimicrotone : Pointer back to the instance of MidiMicrotone

Definition at line 36 of file midimicrotonalhelper.cpp.

Here is the call graph for this function:

Member Function Documentation

void MidiMicrotonalHelper::afterTouch	(	int	channel,
		int	key,
		int	volume,
		double	delta
	)

Polyphonic Key Pressure (Aftertouch).

Parameters

channel
key
volume
delta

Definition at line 136 of file midimicrotonalhelper.cpp.

void MidiMicrotonalHelper::allNotesOff ( )

Turn all notes off.

Definition at line 232 of file midimicrotonalhelper.cpp.

Here is the call graph for this function:

void MidiMicrotonalHelper::bankSelect	(	int	bank,
		double	delta
	)

MidiMicrotonalHelper::bankSelect.

Parameters

bank
delta

Definition at line 184 of file midimicrotonalhelper.cpp.

void MidiMicrotonalHelper::controlChange	(	int	channel,
		int	control,
		int	value,
		double	delta
	)

Polyphonic Key Pressure (Aftertouch).

Parameters

channel
control
value
delta

Definition at line 162 of file midimicrotonalhelper.cpp.

int Log::getVerbosity ( )

inherited

Get the actual verbosity level.

Returns: : Verbosity level (1...4)

Definition at line 118 of file log.cpp.

void MidiMicrotonalHelper::localControl ( bool on )

Enable local control.

If one plays on an electronic keyboard it is per default controlled locally, that is, pressing a key produces a sound. This means that the keyboard unit and the sound-generating unit in the keyboard are connected. For playing in just intonation, we have to switch the local control off and send all data through the attached computer.

Parameters

on	: True = local control, false = no local control

Definition at line 352 of file midimicrotonalhelper.cpp.

void MidiMicrotonalHelper::playNote	(	bool	on,
		int	mappedChannel,
		int	key,
		int	vol,
		double	delta
	)

private

Definition at line 286 of file midimicrotonalhelper.cpp.

Here is the call graph for this function:

void MidiMicrotonalHelper::resetAllControllers ( )

Reset all controllers.

Definition at line 248 of file midimicrotonalhelper.cpp.

void MidiMicrotonalHelper::sendInitialMidiCommands ( void )

slot

Send initial Midi commands.

This function sends the intial MIDI commands for initialization. In particular it resets all channels to the same mInstrument. Moreover, it switches the local control of the target device off.

Definition at line 326 of file midimicrotonalhelper.cpp.

Here is the call graph for this function:

void MidiMicrotonalHelper::setInstrument ( int instrument )

Set the instrument (program)

Parameters

instrument : Midi instrument number (0...127)

Definition at line 57 of file midimicrotonalhelper.cpp.

void MidiMicrotonalHelper::setPitchBend	(	int	channel,
		double	pitch
	)

private

Definition at line 300 of file midimicrotonalhelper.cpp.

void Log::setVerbosity ( int verbosity )

inherited

Set the verbosity level of the class-specific messages.

Parameters

verbosity : Verbosity level (1...4)

Definition at line 107 of file log.cpp.

void MidiMicrotonalHelper::tune	(	int	key,
		double	pitch
	)

MidiMicrotonalHelper::tune.

This function receives the key number and the corresponding cent deviatin from the tuner module. It scans the array to look up which of the 16 channels currently plays this key. If so, the pitch bend function is called.

Parameters

key	: Number of the key
pitch	: pitch versus ET in cent

Definition at line 269 of file midimicrotonalhelper.cpp.

Here is the call graph for this function:

void MidiMicrotonalHelper::turnNoteOff	(	int	channel,
		int	key,
		double	delta
	)

Turn note off.

Parameters

channel
key
delta

Definition at line 211 of file midimicrotonalhelper.cpp.

Here is the call graph for this function:

void MidiMicrotonalHelper::turnNoteOn	(	int	channel,
		int	key,
		int	volume,
		double	delta
	)

Turn note on.

Parameters

channel
key
volume
delta
