QuickTime Real Time playback for jMusic. * Score 1 is used first then score 2 and repeat infinitly. * While one score is playing the other score is updating. * Any class calling QTRT must implement two methods, * updateScore1() and updateScore2() * It is the responsibility of the calling app to * update the scores as required. Syncronisation of * this can be assisted by polling the value of the * score1PlayingFlag boolean variable. * A swing GUI is provided to adjust the scheduling * parameters as required. * The scoreLength argument is critical as it determines the * size of the scores created when updateScore methods * are called, which (of course) also changes the delay * between update calls. It can be changed using the * setScoreLength() method. * Remember to call the startPlayback() method (only once) or else * nothing will happen ;) Use suspendPlayback() and * resumePlayback() to interupt the playback once started. * * @param Score the first score object * @param Score the first score object * @param Object the class the calls this class * * @author Andrew Brown

Method Detail

startPlayback

public void startPlayback()
Begin the cycling playback of the scores.

playCycle

private void playCycle()
Shedule score playback na d score updating when required.

setScoreLength

public void setScoreLength(double newLength)
Specifies the length of a score to be played. * Changes the interval between score update calls.

getScoreLength

public double getScoreLength()
Reports the current score length setting.

setScore

public void setScore(jm.music.data.Score s)
Specifies the score to be played.

setTempo

public void setTempo(double newTempo)
Specifies the speed in beats per minute.

getTempo

public double getTempo()
Reports the current speed in beats per minute.

setNextTempo

public void setNextTempo(double newTempo)
Specifies the speed in beats per minute.

updateTempo

public void updateTempo()
Updates the current speed in beats per minute * based on a waiting tempo change. * This prevents gaps or overlaps in the playback * which can occur from the use of setTempo() * which updates immediatly.

setCycleCount

public void setCycleCount(int newCount)
Specify the number ot count cycles from.

getCycleCount

public int getCycleCount()
Report the number of times the cycle method has been run. * Useful for counting beats , bars, phrases or * whatever the chunk passed to the QTRT.

resumePlayback

public void resumePlayback()
If paused, restart playback.

suspendPlayback

public void suspendPlayback()
Pause playback.

setSleepTime

public void setSleepTime(double newSleepTime)
Update the sleep time value..

getSleepTime

public double getSleepTime()
Report the current loop gap time.

setTheGap

public void setTheGap(double newGap)
Update the sleep time value..

getTheGap

public double getTheGap()
Report the current loop gap time.

settings

public void settings()
Open a GUI with sliders to adjust the scheduler loading. * Used to optimise the timing and efficiecy of the real time * QuickTime playback.

stateChanged

public void stateChanged(javax.swing.event.ChangeEvent e)
Description copied from interface: javax.swing.event.ChangeListener
Called by an object to notify the listener that the object's state has changed. The incoming event identifies the source of the event, allowing the listener to differentiate when it is listening for changes in multiple sources.

Specified by:
stateChanged in interface javax.swing.event.ChangeListener

changeTempo

private void changeTempo()

changeSleep

private void changeSleep()

changeGap

private void changeGap()

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent ae)
Description copied from interface: java.awt.event.ActionListener
This method is invoked when an action occurs.

Specified by:
actionPerformed in interface java.awt.event.ActionListener
