Hi, I was reading this post... How to write a java program that writes a MIDI file

This Java code generate the contents of the File.

[positionFile]:Hex Byte(signed value Byte): Representation, ....

Below the content


[00]:4D( 77):M, [01]:54( 84):T, [02]:68( 104):h, [03]:64( 100):d, [04]:00( 0): , [05]:00( 0): , [06]:00( 0): , [07]:06( 6): ,

If you can see ...

[22]:00( 0): , [23]:F0( -16):ð, [24]:05( 5): , [25]:7E( 126):~, [26]:7F( 127):, [27]:09( 9): , [28]:01( 1): , [29]:F7( -9):÷,

like result of Java code:

byte[] b = {(byte) 0xF0, 0x7E, 0x7F, 0x09, 0x01, (byte) 0xF7};

      SysexMessage sm = new SysexMessage();

      sm.setMessage(b, 6);

      MidiEvent me = new MidiEvent(sm, (long) 0);

      t.add(me);

The question is:

How determine the length of SysexMessage/SysexEventType, in order to parse correctly the File and obtain te next event?...
