Interface Sequencer

All Superinterfaces:
MidiDevice
public interface Sequencer
extends MidiDevice
A hardware or software device that plays back a MIDI sequence is known as a sequencer. A MIDI sequence contains lists of time-stamped MIDI data, such as might be read from a standard MIDI file. Most sequencers also provide functions for creating and editing sequences.

The Sequencer interface includes methods for the following basic MIDI sequencer operations:

In addition, the following operations are supported, either directly, or indirectly through objects that the Sequencer has access to:

Method Details

addControllerEventListener

public int[] addControllerEventListener(ControllerEventListener listener,
                                        int[] controllers)
Registers a controller event listener to receive notification whenever the sequencer processes a control-change event of the requested type or types. The types are specified by the controllers argument, which should contain an array of MIDI controller numbers. (Each number should be between 0 and 127, inclusive. See the MIDI 1.0 Specification for the numbers that correspond to various types of controllers.)

The returned array contains the MIDI controller numbers for which the listener will now receive events. Some sequencers might not support controller event notification, in which case the array has a length of 0. Other sequencers might support notification for some controllers but not all. This method may be invoked repeatedly. Each time, the returned array indicates all the controllers that the listener will be notified about, not only the controllers requested in that particular invocation.

Parameters:
listener - the controller event listener to add to the list of registered listeners
controllers - the MIDI controller numbers for which change notification is requested
Returns:
the numbers of all the MIDI controllers whose changes will now be reported to the specified listener
See Also:
removeControllerEventListener(ControllerEventListener,int[]), ControllerEventListener

addMetaEventListener

public boolean addMetaEventListener(MetaEventListener listener)
Registers a meta-event listener to receive notification whenever a meta-event is encountered in the sequence and processed by the sequencer. This method can fail if, for instance,this class of sequencer does not support meta-event notification.
Parameters:
listener - listener to add
Returns:
true if the listener was successfully added, otherwise false

setLoopCount

public void setLoopCount(int count)
Sets the number of repetitions of the loop for playback. When the playback position reaches the loop end point, it will loop back to the loop start point count times, after which playback will continue to play to the end of the sequence.

If the current position when this method is invoked is greater than the loop end point, playback continues to the end of the sequence without looping, unless the loop end point is changed subsequently.

A count value of 0 disables looping: playback will continue at the loop end point, and it will not loop back to the loop start point. This is a sequencer's default.

If playback is stopped during looping, the current loop status is cleared; subsequent start requests are not affected by an interrupted loop operation.

Parameters:
count - the number of times playback should loop back from the loop's end position to the loop's start position, or LOOP_CONTINUOUSLY to indicate that looping should continue until interrupted
Throws:
IllegalArgumentException - if count is negative and not equal to LOOP_CONTINUOUSLY
Since:
1.5

setLoopEndPoint

public void setLoopEndPoint(long tick)
Sets the last MIDI tick that will be played in the loop. If the loop count is 0, the loop end point has no effect and playback continues to play when reaching the loop end point.

A value of -1 for the ending point indicates the last tick of the sequence. Otherwise, the ending point must be greater than or equal to the starting point, and it must fall within the size of the loaded sequence.

A sequencer's loop end point defaults to -1, meaning the end of the sequence.

Parameters:
tick - the loop's ending position, in MIDI ticks (zero-based), or -1 to indicate the final tick
Throws:
IllegalArgumentException - if the requested loop point cannot be set, usually because it falls outside the sequence's duration or because the ending point is before the starting point
Since:
1.5
See Also:
setLoopStartPoint(long), setLoopCount(int), getLoopEndPoint(), start()

setLoopStartPoint

public void setLoopStartPoint(long tick)
Sets the first MIDI tick that will be played in the loop. If the loop count is greater than 0, playback will jump to this point when reaching the loop end point.

A value of 0 for the starting point means the beginning of the loaded sequence. The starting point must be lower than or equal to the ending point, and it must fall within the size of the loaded sequence.

A sequencer's loop start point defaults to start of the sequence.

Parameters:
tick - the loop's starting position, in MIDI ticks (zero-based)
Throws:
IllegalArgumentException - if the requested loop start point cannot be set, usually because it falls outside the sequence's duration or because the start point is after the end point
Since:
1.5
See Also:
setLoopEndPoint(long), setLoopCount(int), getLoopStartPoint(), start()

setMasterSyncMode

public void setMasterSyncMode(Sequencer.SyncMode sync)
Sets the source of timing information used by this sequencer. The sequencer synchronizes to the master, which is the internal clock, MIDI clock, or MIDI time code, depending on the value of sync. The sync argument must be one of the supported modes, as returned by getMasterSyncModes().
Parameters:
sync - the desired master synchronization mode

setSlaveSyncMode

public void setSlaveSyncMode(Sequencer.SyncMode sync)
Sets the slave synchronization mode for the sequencer. This indicates the type of timing information sent by the sequencer to its receiver. The sync argument must be one of the supported modes, as returned by getSlaveSyncModes().
Parameters:
sync - the desired slave synchronization mode
See Also:
Sequencer.SyncMode.MIDI_SYNC, Sequencer.SyncMode.MIDI_TIME_CODE, Sequencer.SyncMode.NO_SYNC, getSlaveSyncModes()

setTempoFactor

public void setTempoFactor(float factor)
Scales the sequencer's actual playback tempo by the factor provided. The default is 1.0. A value of 1.0 represents the natural rate (the tempo specified in the sequence), 2.0 means twice as fast, etc. The tempo factor does not affect the values returned by getTempoInMPQ() and getTempoInBPM(). Those values indicate the tempo prior to scaling.

Note that the tempo factor cannot be adjusted when external synchronization is used. In that situation, setTempoFactor always sets the tempo factor to 1.0.

Parameters:
factor - the requested tempo scalar

setTrackSolo

public void setTrackSolo(int track,
                         boolean solo)
Sets the solo state for a track. If solo is true only this track and other solo'd tracks will sound. If solo is false then only other solo'd tracks will sound, unless no tracks are solo'd in which case all un-muted tracks will sound.

This method may fail for a number of reasons. For example, the track number specified may not be valid for the current sequence, or the sequencer may not support this functionality. An application which needs to verify whether this operation succeeded should follow this call with a call to getTrackSolo(int).

Parameters:
track - the track number. Tracks in the current sequence are numbered from 0 to the number of tracks in the sequence minus 1.
solo - the new solo state for the track. true implies the track should be solo'd, false implies the track should not be solo'd.

start

public void start()
Starts playback of the MIDI data in the currently loaded sequence. Playback will begin from the current position. If the playback position reaches the loop end point, and the loop count is greater than 0, playback will resume at the loop start point for the number of repetitions set with setLoopCount. After that, or if the loop count is 0, playback will continue to play to the end of the sequence.

The implementation ensures that the synthesizer is brought to a consistent state when jumping to the loop start point by sending appropriate controllers, pitch bend, and program change events.

Throws:
IllegalStateException - if the Sequencer is closed.

startRecording

public void startRecording()
Starts recording and playback of MIDI data. Data is recorded to all enabled tracks, on the channel(s) for which they were enabled. Recording begins at the current position of the sequencer. Any events already in the track are overwritten for the duration of the recording session. Events from the currently loaded sequence, if any, are delivered to the sequencer's transmitter(s) along with messages received during recording.

Note that tracks are not by default enabled for recording. In order to record MIDI data, at least one track must be specifically enabled for recording.

Throws:
IllegalStateException - if the Sequencer is closed.
See Also:
startRecording(), recordEnable(Track,int), recordDisable(Track)

stop

public void stop()
Stops recording, if active, and playback of the currently loaded sequence, if any.
Throws:
IllegalStateException - if the Sequencer is closed.
See Also:
start(), isRunning()
