◆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.

For Bulk Dump Request, you must use the Address and Size listed in the following Bulk Dump Request.

■Parameter Dump Request

Address(H)	Size(H)
10 00 00 00	00 00 00 00
	(All User Songs: dump request for all user songs)
40 00 00 00	00 00 00 00
	(Setup: dump request for all setup except Device ID and
	LCD Contrast)
41 mm 00 00	00 00 00 00
	(One Drum Kit: single drum kit dump request specified by
	"mm")
41 7f 00 00	00 00 00 00
	(All Drum Kits: dump request for all drum kitsÅj
mm = 00H - 62H	(Drum Kit No.1 - 99)

*Data of preset song (No.1 - 150) cannot be transmitted.

*Make sure to set "00 00 00 00" for the data size.

■Decimal and Hexadecimal table

In MIDI documentation, data values and addresses/sizes of exclusive messages etc. are expressed as hexadecimal values for each 7 bits.

The following table shows how these correspond to decimal numbers.

+——————————————————————————————————————————————————————————+ Dec. Hex. Dec. Hex. Dec. Hex. Dec. Hex. ——————+——————++——————+——————++——————+——————++——————+——————

*Decimal values such as MIDI channel, bank select, and program change are listed as one(1) greater than the values given in the above table.

*A 7-bit byte can express data in the range of 128 steps. For data where greater precision is required, we must use two or more bytes. For example, two hexadecimal numbers aa bbH expressing two 7-bit bytes would indicate a value of aa x 128 + bb.

*In the case of values which have a +- sign, 00H = -64, 40H = +- 0, and 7FH = +63, so that the decimal expression would be 64 less than the value given in the above chart. In the case of two types, 00 00H = -8192, 40 00H = +- 0, and 7F 7FH = +8191. For example if aa bbH were expressed as decimal, this would be aa bbH - 40 00H = aa x 128 + bb - 64 x 128.

*Data marked "nibbled" is expressed in hexadecimal in 4-bit units. A value expressed as a 2-byte nibble 0a 0bH has the value of a x 16 + b.

<Example1> What is the decimal expression of 5AH ?

From the preceding table, 5AH = 90

<Example2> What is the decimal expression of the value 12 34H

given as hexadecimal for each 7 bits?

From the preceding table, since 12H = 18 and 34H = 52

18 x 128 + 52 = 2356

<Example3> What is the decimal expression of the nibbled value 0A 03 09 0D ?

From the preceding table, since 0AH = 10, 03H = 3, 09H = 9, 0DH = 13

((10 x 16 + 3) x 16 + 9) x 16 + 13 = 41885

<Example4> What is the nibbled expression of the decimal value 1258 ?

16) 1258

16) 78 ...10

16)4 ...14

0 ...4

Since from the preceding table, 0 = 00H, 4 = 04H, 14 = 0EH, 10 = 0AH , the answer

is 00 04 0E 0A
