MidiTrack Class Reference

#include <track.h>

List of all members.


Detailed Description

Stores a MIDI track.Stores a MIDI track with a simple API.

This can be thought of as a list of MIDI events.

The data types used to store the track is similar to how events are stored on a MIDI file, but used in a way that allows for faster parses.

This class is used on MidiPlayer::loadSong() to load the song and later play it with MidiPlayer::play().

Definition at line 146 of file track.cc.

int MidiTrack::msPassed ( ulong  ms  ) 

Makes the iterator advance the given number of milliseconds.

Returns:
0 if OK, and 1 if you didn't handle this track well and you forgot to take an event (thing that will never happen if you use MidiPlayer::play() ).

Definition at line 158 of file track.cc.

int MidiTrack::currentMs ( double  ms  ) 

Returns the current millisecond which the iterator is at.

Definition at line 174 of file track.cc.

ulong MidiTrack::waitTicks ( void   )  [inline]

Returns the number of ticks left for the next event.

Definition at line 205 of file track.h.

Change the tempo of the song.

Definition at line 544 of file track.cc.

void MidiTrack::readEvent ( MidiEvent ev  )
