4. Bulk Dump
Bulk Dump allows you to transmit a large amount of data at once, and is convenient for storing settings for the entire unit on a computer or sequencer.
To make the SC-8820 perform a Bulk Dump transmission, send it a “Bulk Dump Request” message. Bulk Dump Request uses the Data Request 1 (RQ1) format, but unlike when transmitting
individual parameters, the “Size” specified by the request message refers not to size of the data but rather specifies the contents of the data. For the data contents corresponding to each Size, refer
to “Parameter dump.”
When the SC-8820 receives a Bulk Dump Request, it will transmit a Bulk Dump in the format given below.
The SC-8820 is also able to transmit a list of its internal sounds. This function can be used to display a list of sounds on a computer.

Parameter dump
❍
Parameter dump request (receive only)
This is a command that requests a set of parameter data, and uses “Data Request 1 (RQ1)” format. The Size specifies the requested data contents.
Address:
0C 00 00
Size:
00 00 00: ALL
request a dump of all parameters
00 00 01: ALL 1
use this when not using USER TONE BANK or USER DRUM SET
00 00 02: ALL 2
use this when USER TONE BANK, USER DRUM SET and DRUM SETUP settings have not been modified
00 00 10: 16-part GS 1
use this when using only 16 Parts
00 00 11: 16-part GS 2
use this when using only 16 Parts, and DRUM SETUP settings have not been modified
00 01 00: USER TONE BANK (ALL)
request a dump of all USER TONE BANK data
00 01 40: USER TONE BANK #64
request a dump of USER TONE BANK #64 data (128 sounds)
00 01 41: USER TONE BANK #65
request a dump of USER TONE BANK #65 data (128 sounds)
00 02 00: USER DRUM SET (ALL)
request a dump of all USER DRUM SET data
00 02 40: USER DRUM SET #65
request a dump of USER DRUM SET #65 data
00 02 41: USER DRUM SET #66
request a dump of USER DRUM SET #66 data
Example) Dump request for all parameters: F0 41 dev 42 11 0C 00 00 00 00 00 74 F7
Normally, using ALL (00 00 00) provides the greatest predictability, but the amount of data is very large, and transmission may take more than half a minute. In order to reduce transmission time
and data volume, we suggest that you request a dump only of the necessary data.

*
When data dumped by the SC-8820 is reloaded into the SC-8820, be aware that the data may not be set correctly if the transmission order of the packets is changed, if the time interval between
packets is changed, or if other messages are inserted between packets.
*
The Parameter Dump data of the SC-8820 includes data for GS format compatible devices, and this data is compatible in both directions. However, depending on the parameters which are
newly extended on the SC-8820, the musical result may differ.
*
If the SC-8820 does not operate correctly with Bulk Dump data from another GS format compatible device, transmit a GS reset before retransmitting the data.
