2. Bulk Dump
Bulk dumps and dump requests are recognized while in the
Play Mode only.
If ALL is selected, all Memory and System Setup data will be
transmitted when MIDI Bulk transmission is carried out.
When Data is divided into several blocks for transmission, there
is an interval of 150ms between the transmission of each block.
Internal parameters are all 8 bit data, bit 7 is assigned as the
1st bit of the MSB (byte), MSB and LSB are always separated
into 2 bytes and transmitted and received in order.
The Dump Request is only received when in the Play Mode.

Bulk data for 8 memories is transmited as in sequence as a
single block. After all memory data has been transmitted,
the system data will then be transmitted. See for
more information on the system data format.
When received, this data overwrites the Edit Buffer’s data.
