Member Function Documentation

void Midi::enableParser

(

bool

enable

)

Enable the input MidiParser.

If the parser is enabled, getInput() will return an error code. Midi messages should instead be retrieved via, e.g.: getMidiParser()->getNextChannelMessage();

Parameters

enable

true to enable the input MidiParser, false to disable it.

MidiParser* Midi::getParser

(

)

Get access to the input parser in use, if any.

Returns

a pointer to the instance of MidiParser, if currently enabled, zero otherwise.

void Midi::setParserCallback ( void(*)(MidiChannelMessage, void *)  callback, void *  arg = NULL  )

inline

Sets the callback to call when a new MidiChannelMessage is available from the input port.

Internally, it calls enableParser() and the MidiParser::setCallback();

Parameters

newCallback	the callback function.
arg	the second argument to be passed to the callback function.

Examples:

FFT-phase-vocoder/render.cpp.

int Midi::readFrom

(

int

port

)

Open the specified input Midi port and start reading from it.

Parameters

port	Midi port to open

Returns

1 on success, -1 on failure

Examples:

FFT-phase-vocoder/render.cpp.

int Midi::writeTo

(

int

port

)

Open the specified output Midi port and prepares to write to it.

Parameters

port	Midi port to open

Returns

1 on success, -1 on failure

int Midi::getInput

(

)

Get received midi bytes, one at a time.

Returns

-1 if no new byte is available, -2 on error, the oldest not yet retrieved midi byte otherwise

int Midi::writeOutput

(

midi_byte_t

byte

)

Writes a Midi byte to the output port

Parameters

byte	the Midi byte to write

Returns

1 on success, -1 on error

int Midi::writeOutput	(	midi_byte_t *	bytes,
		unsigned int	length
	)

Writes Midi bytes to the output port

Parameters

bytes	an array of bytes to be written
length	number of bytes to write

Returns

1 on success, -1 on error

MidiParser* Midi::getMidiParser

(

)

Gives access to the midi parser, if it has been activated.

Returns

a pointer to the midi parser if active, zero otherwise
