For information about “Address” and “Byte Count” fields, refer to Table 2 on the SOUND
LIST & MIDI DATA booklet.
Checksum value is set such that the sum of Address, Byte Count, and Checksum has value
zero in its seven least significant bits.
No more than 512 bytes should be sent in a single transmission. If the Dump Request asks
for more than 512 bytes, data should be sent in packets of 512 bytes or less, with at least
120msec between transmission of consecutive packets.
