Detailed Description

Gravis Ultrasound synthesizer output class .

This class is used to send midi events to synthesizers on GUS cards.

GUSOut inherits MidiOut and supports the same simple API.

The recommended way to use this class is by using a DeviceManager object, and use the DeviceManager::setPatchesToUse() member which will call the setPatchesToUse() member in this class.

Sends MIDI events to GUS synths

void GUSOut::closeDev ( void   )  [virtual]

See MidiOut::closeDev().

Reimplemented from MidiOut.

Definition at line 169 of file gusout.cc.

void GUSOut::initDev ( void   )  [virtual]

See MidiOut::initDev().

Reimplemented from MidiOut.

Definition at line 178 of file gusout.cc.

uchar  note,
uchar  vel 
) [virtual]

See MidiOut::keyPressure().

Reimplemented from MidiOut.

Definition at line 262 of file gusout.cc.

int GUSOut::loadPatch ( int  pgm  ) 

Loads a single patch on the synthesizer memory.

Parameters:
pgm is the number of the GM patch when pgm is between 0 and 127. Values from 128 to 255 are used to represent the percussion instruments.
Returns:
0 if OK and -1 if there was an error (patch not found, not enough memory, etc.)

void GUSOut::noteOff ( uchar  chn,
uchar  note,
uchar  vel 
) [virtual]

See MidiOut::noteOff().

Reimplemented from MidiOut.

Definition at line 247 of file gusout.cc.

void GUSOut::noteOn ( uchar  chn,
uchar  note,
uchar  vel 
) [virtual]

See MidiOut::noteOn().

Reimplemented from MidiOut.

Definition at line 217 of file gusout.cc.

void GUSOut::openDev ( int  sqfd  )  [virtual]

See MidiOut::openDev().

Reimplemented from MidiOut.

Definition at line 137 of file gusout.cc.

int GUSOut::patch ( int  p  ) 

Returns p if the patch with number p has been correctly loaded.

In the case it hasn't been loaded, it returns the number of another patch that is loaded and that should be used instead.

loadPatch()

setPatchesToUse()

Definition at line 208 of file gusout.cc.

void GUSOut::setGUSPatchesDirectory ( const char *  dir  )  [static]

Sets the directory where the GUS patches are stored, that is, where the acpiano.pat, .

.. files can be found.

It will store a copy of the parameter, so you should delete the memory used by the parameter you passed.

Definition at line 322 of file gusout.cc.

void GUSOut::setPatchesToUse ( int *  patchesused  ) 

See DeviceManager::setPatchesToUse() .

All the information about this member is explained there because it's (for now) just a simple call to this function when the device used is a GUS device, and you're supposed to use a DeviceManager object instead of a GUSOut object except in rare ocassions.

patch()

loadPatch()

Definition at line 525 of file gusout.cc.

void GUSOut::sysex ( uchar *  data,
ulong  size 
) [virtual]

It's an empty function, as GUS synths don't support System Exclusive messages.

Reimplemented from MidiOut.

Definition at line 317 of file gusout.cc.
