Note the - * avoidance of the phrase "MIDI data." Despite its name, - * MidiParser derivatives can be used to manage a wide - * variety of event-based music formats. It is, however, - * based on the premise that the format in question can - * be played in the form of specification MIDI events. - * - * In order to use MidiParser to parse your music format, - * follow these steps: - * - * <b>STEP 1: Write a MidiParser derivative.</b> - * The MidiParser base class provides functionality - * considered common to the task of parsing event-based - * music. In order to parse a particular format, create - * a derived class that implements, at minimum, the - * following format-specific methods: - * - loadMusic - * - parseNextEvent - * - * In addition to the above functions, the derived class - * may also override the default MidiParser behavior for - * the following methods: - * - resetTracking - * - allNotesOff - * - unloadMusic - * - property - * - getTick - * - * Please see the documentation for these individual - * functions for more information on their use. - * - * The naming convention for classes derived from - * MidiParser is MidiParser_XXX, where "XXX" is some - * short designator for the format the class will - * support. For instance, the MidiParser derivative - * for parsing the Standard MIDI File format is - * MidiParser_SMF. - * - * <b>STEP 2: Create an object of your derived class.</b> - * Each MidiParser object can parse at most one (1) song - * at a time. However, a MidiParser object can be reused - * to play another song once it is no longer needed to - * play whatever it was playing. In other words, MidiParser - * objects do not have to be destroyed and recreated from - * one song to the next. - * - * <b>STEP 3: Specify a MidiDriver to send events to.</b> - * MidiParser works by sending MIDI and meta events to a - * MidiDriver. In the simplest configuration, you can plug - * a single MidiParser directly into the output MidiDriver - * being used. However, you can only plug in one at a time; - * otherwise channel conflicts will occur. Furthermore, - * meta events that may be needed to interactively control - * music flow cannot be handled because they are being - * sent directly to the output device. - * - * If you need more control over the MidiParser while it's - * playing, you can create your own "pseudo-MidiDriver" and - * place it in between your MidiParser and the output - * MidiDriver. The MidiParser will send events to your - * pseudo-MidiDriver, which in turn must send them to the - * output MidiDriver (or do whatever special handling is - * required). - * - * To specify the MidiDriver to send music output to, - * use the MidiParser::setMidiDriver method. - * - * <b>STEP 4: Specify the onTimer call rate.</b> - * MidiParser bases the timing of its parsing on an external - * clock. Every time MidiParser::onTimer is called, a bit - * more music is parsed. You must specify how many - * microseconds will occur between each call to onTimer, - * in order to ensure an accurate music tempo. - * - * To set the onTimer call rate, in microseconds, - * use the MidiParser::setTimerRate method. The onTimer - * call rate will typically match the timer rate for - * the output MidiDriver used. This rate can be obtained - * by calling MidiDriver::getBaseTempo. - * - * <b>STEP 5: Load the music.</b> - * MidiParser requires that the music data already be loaded - * into memory. The client code is responsible for memory - * management on this block of memory. That means that the - * client code must ensure that the data remain in memory - * while the MidiParser is using it, and properly freed - * after it is no longer needed. Some MidiParser variants may - * require internal buffers as well; memory management for those - * buffers is the responsibility of the MidiParser object. - * - * To load the music into the MidiParser, use the - * MidiParser::loadMusic method, specifying a memory pointer - * to the music data and the size of the data. (NOTE: Some - * MidiParser variants don't require a size, and 0 is fine. - * However, when writing client code to use MidiParser, it is - * best to assume that a valid size will be required. - * - * Convention requires that each implementation of - * MidiParser::loadMusic automatically set up default tempo - * and current track. This effectively means that the - * MidiParser will start playing as soon as timer events - * start coming in. - * - * <b>STEP 6: Activate a timer source for the MidiParser.</b> - * The easiest timer source to use is the timer of the - * output MidiDriver. You can attach the MidiDriver's - * timer output directly to a MidiParser by calling - * MidiDriver::setTimerCallback. In this case, the timer_proc - * will be the static method MidiParser::timerCallback, - * and timer_param will be a pointer to your MidiParser object. - * - * This configuration only allows one MidiParser to be driven - * by the MidiDriver at a time. To drive more MidiDrivers, you - * will need to create a "pseudo-MidiDriver" as described earlier, - * In such a configuration, the pseudo-MidiDriver should be set - * as the timer recipient in MidiDriver::setTimerCallback, and - * could then call MidiParser::onTimer for each MidiParser object. - * - * <b>STEP 7: Music shall begin to play!</b> - * Congratulations! At this point everything should be hooked up - * and the MidiParser should generate music. Note that there is - * no way to "stop" the MidiParser. You can "pause" the MidiParser - * simply by not sending timer events to it, or you can call - * MidiParser::unloadMusic to permanently stop the music. (This - * method resets everything and detaches the MidiParser from the - * memory block containing the music data.) - */ -class MidiParser { -protected: - uint16 _active_notes[128]; ///< Each uint16 is a bit mask for channels that have that note on. - NoteTimer _hanging_notes[32]; ///< Maintains expiration info for up to 32 notes. - ///< Used for "Smart Jump" and MIDI formats that do not include explicit Note Off events. - byte _hanging_notes_count; ///< Count of hanging notes, used to optimize expiration. - - MidiDriver *_driver; ///< The device to which all events will be transmitted. - uint32 _timer_rate; ///< The time in microseconds between onTimer() calls.
