* The amount of data that can be transmitted at once is fixed for each type of data.
Data that does not have the specified starting address and data size will not be
received. Refer to the explanation in 3. Bulk Dump.
* There must be an interval of at least 40 ms between each exclusive message that
is sent.
* Also, you must leave an interval of at least 500 ms after transmitting one set of
bulk dump data.
3. Bulk dump
Bulk dump allows a large amount of data to be transferred in a single operation.
For example, this can be used to store all settings of a device into a computer or
sequencer.
On the PCR-1, a bulk dump will be transmitted when you execute the Bulk mode
operation BULK TX. The bulk dump is transmitted as several exclusive messages.

* You must leave an interval of at least 40 ms between each exclusive message.
* In the case of ALL BULK, the contents of memories 1--F will be transmitted as
the current memory, consecutively from memory 1 through memory F. After
transmitting one set of bulk dump data, you must leave an interval of at least
500 ms.
* Please be aware that if you modify the data dumped from the PCR-1 by
changing the order in which the exclusive messages are transmitted, by
inserting other messages between the system exclusive messages, or by
speeding up the timing of the transmission, the data may not be set correctly
when the PCR-1 receives it.
