Detailed Description

MIDI output device.

This device supports both MT-32 MIDI, as used in Kyrandia 1 and 2, and GM MIDI, as used in Kyrandia 2.

Member Function Documentation

init()

bool Kyra::SoundMidiPC::init ( )

overridevirtual

Initializes the output device.

Returns

true on success, else false

Implements Kyra::Sound.

updateVolumeSettings()

void Kyra::SoundMidiPC::updateVolumeSettings ( )

overridevirtual

Updates internal volume settings according to ConfigManager.

Reimplemented from Kyra::Sound.

initAudioResourceInfo()

void Kyra::SoundMidiPC::initAudioResourceInfo ( int  set, void *  info  )

overridevirtual

Assigns static resource data with information on how to load audio resources to

Parameters

set	value defined in AudioResourceSet enum info various types of resource info data (file list, file name pattern, struct, etc. - depending on the inheriting driver type)

Implements Kyra::Sound.

selectAudioResourceSet()

void Kyra::SoundMidiPC::selectAudioResourceSet ( int  set )

overridevirtual

Select audio resource set.

Parameters

set	value defined in AudioResourceSet enum

Implements Kyra::Sound.

hasSoundFile()

bool Kyra::SoundMidiPC::hasSoundFile ( uint  file ) const

overridevirtual

Checks if a given sound file is present.

Parameters

track

track number

Returns

true if available, false otherwise

Implements Kyra::Sound.

loadSoundFile() [1/2]

void Kyra::SoundMidiPC::loadSoundFile ( uint  file )

overridevirtual

Load a specifc sound file for use of playing music and sound effects.

Implements Kyra::Sound.

loadSoundFile() [2/2]

void Kyra::SoundMidiPC::loadSoundFile ( const Common::Path &  file )

overridevirtual

Load a sound file for playing music (and sometimes sound effects) from.

Implements Kyra::Sound.

loadSfxFile()

void Kyra::SoundMidiPC::loadSfxFile ( const Common::Path &  file )

overridevirtual

Load a sound file for playing sound effects from.

Reimplemented from Kyra::Sound.

playTrack()

void Kyra::SoundMidiPC::playTrack ( uint8  track )

overridevirtual

Plays the specified track.

Parameters

track

track number

Implements Kyra::Sound.

haltTrack()

void Kyra::SoundMidiPC::haltTrack ( )

overridevirtual

Stop playback of the current track.

Implements Kyra::Sound.

isPlaying()

bool Kyra::SoundMidiPC::isPlaying ( ) const

overridevirtual

Checks if the sound driver plays any sound.

Returns

true if playing, false otherwise

Reimplemented from Kyra::Sound.

playSoundEffect()

void Kyra::SoundMidiPC::playSoundEffect ( uint16  track, uint8  volume = 0xFF  )

overridevirtual

Plays the specified sound effect.

Parameters

track

sound effect id

Implements Kyra::Sound.

stopAllSoundEffects()

void Kyra::SoundMidiPC::stopAllSoundEffects ( )

overridevirtual

Stop playback of all sfx tracks.

Reimplemented from Kyra::Sound.

beginFadeOut()

void Kyra::SoundMidiPC::beginFadeOut ( )

overridevirtual

Starts fading out the volume.

This keeps fading out the output until it is silenced, but does not change the volume set by setVolume! It will automatically reset the volume when playing a new track or sound effect.

Implements Kyra::Sound.

pause()

void Kyra::SoundMidiPC::pause ( bool  paused )

overridevirtual

Stops all audio playback when paused. Continues after end of pause.

Reimplemented from Kyra::Sound.
