I'm try to do some programming on QY20 SysEx, for decode bulk dump and encode midi event back to bulk dump, however I couldn't proceed with the manual 'MIDI File Format'. Say when dumping a song from QY, I could see one 'SQ' and a number of 'QY'. It is easy to follow the 'SQ' and the header portion of 'QY' but I couldn't decode the data portion. [Chart4] tells each 'QY' must start with 'F0h MNh' but none in the 'QY' data. The 'Notes' section tells each event must start with the MS-bit set but all bytes in the data portion have their MS-bit off. I tried to narrow the problem down into notes-only sequence and complete the '.mid' file againt the '.syx' file but still no clue. Anyone did this before, or something relevant? Hints, solution, or even counter problem for brain storming are all welcome.
