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
