Constructor Detail

MidiFileFormat

public MidiFileFormat(int type,
                      float divisionType,
                      int resolution,
                      int bytes,
                      long microseconds)

Constructor without properties

Parameters:

type - 0(SMF 0), or 1(SMF 1)

divisionType - Sequence.PPQ, Sequence.SMPTE_24, Sequence.SMPTE_25, Sequence.SMPTE_30DROP, or Sequence.SMPTE_30.

resolution -

• divisionType == Sequence.PPQ : 0 - 0x7fff. typically 24, 480
• divisionType == Sequence.SMPTE_24, Sequence.SMPTE_25, Sequence.SMPTE_30DROP, Sequence.SMPTE_30 : 0 - 0xff

bytes - the length of file

microseconds - the length of time(in micro seconds)
