How to request for a "Patch Dump" SysX message (technical)
Preparations:
- switch on "MIDI EXT." on the DK70 ("MIDI INT." switched on is also handy),
- connect MIDI IN and OUT to the computer OUT and IN.
Send the Patch Dump Request using computer software.
F0 21 00 xx F7
Explanation of the dump request message:
|
A SysX message is usually represented using hexadecimal numbers, because that is close to the way computers communicate with each other. |
The DK70 responds by sending a 50 bytes long message back containing all the Patch parameters.
Save this message to a file and upload the file.
Example of a dump (this is Patch #93):
F0 21 04 5D 02 0F 08 06 04 0A 00 0E 09 02 04 0F 09 00
0F 00 04 01 0A 0F 0F 0F 0F 01 01 00 00 07 00 04 0F 00
00 01 03 00 00 0C 08 05 08 04 04 0B 0D F7
Technical
You can upload any file, as long as it is recognized as a SysX file for the DK70.
This means:
-
a 50 bytes file
- that starts with the 3 bytes SIEL header: F0 21 04
- followed by the patch number and the DK70 id: 02
- then 44 bytes of data that contain all the Patch parameters
- and at last the 1 byte 'sysx end' marker: F7
This app does not store an uploaded file in a database, so you have to take care of backups yourself.
