byte *	_buffer
int8	_noteChannelToTrack [16]
Protected Attributes inherited from MidiParser
uint16	_activeNotes [128]
	Each uint16 is a bit mask for channels that have that note on.
NoteTimer	_hangingNotes [32]
	Used for "Smart Jump" and MIDI formats that do not include explicit Note Off events. More...
byte	_hangingNotesCount
	Count of hanging notes, used to optimize expiration.
MidiDriver_BASE *	_driver
	The device to which all events will be transmitted.
uint32	_timerRate
	The time in microseconds between onTimer() calls. Obtained from the MidiDriver.
uint32	_ppqn
	Pulses Per Quarter Note. (We refer to "pulses" as "ticks".)

	Microseconds per quarter note.
uint32	_psecPerTick
	Microseconds per tick (_tempo / _ppqn).
uint32	_sysExDelay
	Number of microseconds until the next SysEx event can be sent.
bool	_autoLoop
	For lightweight clients that don't provide their own flow control.
bool	_smartJump
	Support smart expiration of hanging notes when jumping.
bool	_centerPitchWheelOnUnload
	Center the pitch wheels when unloading a song.
bool	_sendSustainOffOnNotesOff
	Send a sustain off on a notes off event, stopping hanging notes.
bool	_disableAllNotesOffMidiEvents
	Don't send All Notes Off MIDI messages.
bool	_disableAutoStartPlayback
	Do not automatically start playback after parsing MIDI data or setting the track.
byte *	_tracks [MAXIMUM_TRACKS]
	Multi-track MIDI formats are supported, up to 120 tracks.
byte	_numTracks
	Count of total tracks for multi-track MIDI formats. 1 for single-track formats.
byte	_activeTrack
	Keeps track of the currently active track, in multi-track formats.
Tracker	_position
	The current time/position in the active track.
EventInfo	_nextEvent
bool	_abortParse
	If a jump or other operation interrupts parsing, flag to abort.
bool	_jumpingToTick
	True if currently inside jumpToTick.
bool	_doParse
	True if the parser should be parsing; false if it should not be active.
bool	_pause
	True if the parser has paused parsing.

Detailed Description

Parser for the MIDI data of the Windows versions of Simon The Sorcerer 1 and 2. This consists of 1 or more type 1 SMF files, preceded by a byte indicating the number of files. The MIDI data for Simon 1 also has broken pitch bend events, as well as incorrect tempos, which are corrected by this parser.

Member Function Documentation

determineDataSize()

int32 AGOS::MidiParser_SimonWin::determineDataSize ( Common::SeekableReadStream *  stream )

overridevirtual

Returns the size in bytes of the MIDI data in the specified stream, or -1 if the size could not be determined. The MIDI data must be in the format handled by the MidiParser subclass that this method is called on. Not every MidiParser subclass has an implementation of this method.

Reimplemented from MidiParser_SMF.
