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-8850 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-8850 receives a Bulk Dump Request, it will transmit a Bulk Dump in the format given below.

The SC-8850 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. Panel button operations allow you to transmit dumps of ALL, ALL 1, 16-part GS 1, 16-part GS 2, USER TONE

BANK (ALL), USER DRUM SET (ALL).

❍Parameter dump

When a Parameter Dump Request is received, or when panel operations initiate a dump transmission, the following data will be transmitted in “Data Set 1 (DT1)” format.

* When data dumped by the SC-8850 is reloaded into the SC-8850, 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-8850 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-8850, the musical result may differ.

* If the SC-8850 does not operate correctly with Bulk Dump data from another GS format compatible device, first initialize the SC-8850 (page 23) before retransmitting the data.

* When another GS format compatible device receives Parameter Dump data that was transmitted by the SC-8850, it may display a message such as “Address Error”, but this is because the

parameter addresses newly extended on the SC-8850 were not recognized by the other device. Parameters which could be recognized by that device have been correctly set.
