Method Detail

openImpl

protected void openImpl()

Description copied from class: TMidiDevice

Subclasses have to override this method to be notified of opening.

Overrides:

openImpl in class TMidiDevice

closeImpl

protected void closeImpl()

Description copied from class: TMidiDevice

Subclasses have to override this method to be notified of closeing.

Overrides:

closeImpl in class TMidiDevice

startImpl

protected void startImpl()

Description copied from class: TSequencer

Subclasses have to override this method to be notified of starting.

Overrides:

startImpl in class TSequencer

stopImpl

protected void stopImpl()

Description copied from class: TSequencer

Subclasses have to override this method to be notified of stopping.

Overrides:

stopImpl in class TSequencer

run

public void run()

Specified by:

run in interface Runnable

setMasterSyncModeImpl

protected void setMasterSyncModeImpl(Sequencer.SyncMode syncMode)

Overrides:

setMasterSyncModeImpl in class TSequencer

setSlaveSyncModeImpl

protected void setSlaveSyncModeImpl(Sequencer.SyncMode syncMode)

Overrides:

setSlaveSyncModeImpl in class TSequencer

setSequence

public void setSequence(Sequence sequence)
                 throws InvalidMidiDataException

Specified by:

setSequence in interface Sequencer

Overrides:

setSequence in class TSequencer

Throws:

InvalidMidiDataException

setMicrosecondPosition

public void setMicrosecondPosition(long lPosition)

Specified by:

setMicrosecondPosition in interface Sequencer

setTickPosition

public void setTickPosition(long lPosition)

Specified by:

setTickPosition in interface Sequencer

getTickPosition

public long getTickPosition()

Specified by:

getTickPosition in interface Sequencer

recordDisable

public void recordDisable(Track track)

Specified by:

recordDisable in interface Sequencer

recordEnable

public void recordEnable(Track track)

recordEnable

public void recordEnable(Track track,
                         int nChannel)

Specified by:

recordEnable in interface Sequencer

isRecording

public boolean isRecording()

Specified by:

isRecording in interface Sequencer

stopRecording

public void stopRecording()

Specified by:

stopRecording in interface Sequencer

startRecording

public void startRecording()

Specified by:

startRecording in interface Sequencer

setTempoImpl

protected void setTempoImpl(float fMPQ)

Description copied from class: TSequencer

Change the tempo of the native sequencer part. This method has to be defined by subclasses according to the native facilities they use for sequenceing. The implementation should not take into account the tempo factor. This is handled elsewhere.

Specified by:

setTempoImpl in class TSequencer

getTimeInMicroseconds

protected long getTimeInMicroseconds()

Retrieve system time in microseconds. This method uses the clock as set with setClock(org.tritonus.midi.device.java.JavaSequencer.Clock).

Returns:

the system time in microseconds

setClock

public void setClock(JavaSequencer.Clock clock)

Set the clock this sequencer should use.

Parameters:

clock - the Clock to be used

Throws:

IllegalStateException - if the sequencer is not closed

getClock

public JavaSequencer.Clock getClock()

Obtain the clock used by this sequencer.

Returns:

the clock currently set for this sequencer
