Yamaha SY55 Product Manual page 191

The song data is transmitted even if the song is empty.
NSEQ track data begins with F0H mnH (m = song number; n = track number)
If bulk dumps are executed in succession, a break of greater than 100
milliseconds is inserted between each transmission.
If an ALL DATA or NSEQ DATA transmission exceeds 512 bytes, it will be broken
down into 512-byte blocks and a byte count and header will be attached to the
beginning of each. A checksum will be attached to the end of each block. A break
of greater than 100 milliseconds will be inserted between each block.
In accordance with the above, a break of greater than 100 milliseconds is
required between each bulk dump when multiple bulk dumps are received.
