* For the address, size, and checksum, refer to ÒExamples of system exclusive messages
and calculating the checksumÓ (p. 249).
* Data whose size is greater than 128 bytes should be divided into packets of 128 bytes or
less and transmitted. Successive ÒData Set 1Ó messages should have at least 20 ms of
time interval between them.
In addition to conventional system exclusive messages, the MC-505 also uses special sys-
tem exclusive messages for operations which require realtime handling, such as knobs.
