Dump preset (001 on bits 6-4):

00h-2fh – Dump preset A-1through D-8in flash 30h-7eh – Invalid (command will be ignored)

7fh	- Dump preset edit
Dump sequence (011 on bits 6-4):
00h	- Dump upper arpeggiator rhythm/sequence
01h	- Dump lower arpeggiator rhythm/sequence

Figure 20 - Command 04h - Dump block request command

Requests a sequence, patch or patch block, preset or preset block dump from Europa. It responds with one or more write block commands (05h). In the case where multiple presets or patches are dumped, multiple write block commands will be sent – one for each patch or preset. Europa delays 70 milliseconds between each write block command transmitted because of this command. This ensures the patches and/or presets will be properly restored when played back to the Jupiter 6, as this delay is required for writing to Europa’s flash memory.

Byte #	Value	Description
0	05h	Write block – patch, preset, or sequence
1	Bitwise	Bit 7	Unused – set to 0
		Bits 6-4	Block type to write:
			000	– Patch
			001	– Preset
			010	– Reserved – not valid
			011	– Arpeggiator step rhythm/sequence
			100-111 – Not valid - Command will be ignored
		Bits 3-0	Unused – set to 0 (other values will invalidate the
			message and it will be ignored.
2-n	Depends on the	See tables below for appropriate patch, preset, or sequence dump
	block type
	Figure 21 - Command 05h - Write block command

Instructs Europa to store a patch, preset, or sequence block in flash or edit buffer. Note that any patch or preset written to flash must delay at least 70 milliseconds afterward to give time for Europa to write to internal flash, otherwise any subsequent command for that time period will be ignored/dropped!

Depending upon byte 1 of the command 05h data stream, one of the following three tables will be applicable:

Byte #	Valid	Name	Description
	range
2	0-47,	Patch number	Place to store patch #0-47 are patch flash positions
	126-127		A-1through F-8. 126=Lower patch edit,
			127=Upper patch edit (used in WHOLE mode)
3	0-16	Patch name length	Length of patch’s name. Can be up to 16 ASCII
			characters
4-19	0-127	Patch name	Patch’s name (in ASCII). This is actually a variable
			length field and is only as long as the data in byte #
			3.
20	0-127	LFO 1 Rate	Set LFO 1’s rate
21	0-127	LFO 1 Delay	Set LFO 1’s delay time
22	0-127	VCO MOD LFO	Set LFO 1’s effect on VCO
