Class Sequence
Objects of this type represent sequences of MIDI messages that can be
played back by a Sequencer.
static float | PPQ- Tempo-based timing.
|
static float | SMPTE_24- 24 frames/second timing.
|
static float | SMPTE_25- 25 frames/second timing.
|
static float | SMPTE_30- 30 frames/second timing.
|
static float | SMPTE_30DROP- 29.97 frames/second timing.
|
protected float | divisionType- The timing division type for this sequence (PPQ or SMPTE*)
|
protected int | resolution- The timing resolution in ticks/beat or ticks/frame, depending on the
division type.
|
protected Vector | tracks- The MIDI tracks used by this sequence.
|
Sequence(float divisionType, int resolution)- Create a MIDI sequence object with no initial tracks.
|
Sequence(float divisionType, int resolution, int numTracks)- Create a MIDI seqence object.

PPQ
public static final float PPQ
Tempo-based timing. Resolution is specified in ticks per beat.
SMPTE_24
public static final float SMPTE_24
24 frames/second timing. Resolution is specific in ticks per frame.
SMPTE_25
public static final float SMPTE_25
25 frames/second timing. Resolution is specific in ticks per frame.
SMPTE_30
public static final float SMPTE_30
30 frames/second timing. Resolution is specific in ticks per frame.
SMPTE_30DROP
public static final float SMPTE_30DROP
29.97 frames/second timing. Resolution is specific in ticks per frame.
divisionType
protected float divisionType
The timing division type for this sequence (PPQ or SMPTE*)
resolution
protected int resolution
The timing resolution in ticks/beat or ticks/frame, depending on the
division type.
tracks
protected Vector
The MIDI tracks used by this sequence.
Sequence
public Sequence(float divisionType,
int resolution)
throws InvalidMidiDataException Create a MIDI sequence object with no initial tracks.
divisionType - the division type (must be one of PPQ or SMPTE_*)resolution - the timing resolution
Sequence
public Sequence(float divisionType,
int resolution,
int numTracks)
throws InvalidMidiDataException Create a MIDI seqence object.
divisionType - the division type (must be one of PPQ or SMPTE_*)resolution - the timing resolutionnumTracks - the number of initial tracks
createTrack
public Track createTrack()
Create a new empty MIDI track and add it to this sequence.
- the newly create MIDI track
deleteTrack
public boolean deleteTrack(Track track)
Remove the specified MIDI track from this sequence.
track - the track to remove
- true if track was removed and false othewise
getDivisionType
public float getDivisionType()
The division type of this sequence.
- division type of this sequence
getMicrosecondLength
public long getMicrosecondLength()
The length of this sequence in microseconds.
- the length of this sequence in microseconds
getPatchList
public Patch[] getPatchList()
Get an array of patches used in this sequence.
- an array of patches used in this sequence
getResolution
public int getResolution()
The timing resolution for this sequence, relative to the division type.
- the timing resolution for this sequence
getTickLength
public long getTickLength()
The length of this sequence in MIDI ticks.
- the length of this sequence in MIDI ticks
getTracks
public Track[] getTracks()
Get an array of MIDI tracks used in this sequence.
- a possibly empty array of tracks
