public Sequence(float divisionType, int resolution) throws InvalidMidiDataException
divisionType
is PPQ (pulses per quarter note) and
the resolution is specified in ticks per beat. For SMTPE timing,
divisionType
specifies the number of frames per
second and the resolution is specified in ticks per frame.
The sequence will contain no initial tracks. Tracks may be
added to or removed from the sequence using createTrack()
and deleteTrack(javax.sound.midi.Track)
.

public Sequence(float divisionType, int resolution, int numTracks) throws InvalidMidiDataException
divisionType
is PPQ (pulses per quarter note) and
the resolution is specified in ticks per beat. For SMTPE timing,
divisionType
specifies the number of frames per
second and the resolution is specified in ticks per frame.
The sequence will be initialized with the number of tracks specified by
numTracks
. These tracks are initially empty (i.e.
they contain only the meta-event End of Track).
The tracks may be retrieved for editing using the getTracks()
method. Additional tracks may be added, or existing tracks removed,
using createTrack()
and deleteTrack(javax.sound.midi.Track)
.
