Creating a backup
=================
Since MIOS V1.4 it is possible to read out all non-volatile memories
by using the SysEx read command. This allows you to create backups
from your system, to analyze the internal data and/or to clone a
complete setup.
Required Steps
~~~~~~~~~~~~~~
o start the SysEx tool of MIDI-Ox
o type one of these SysEx commands (depending on PIC derivative) into the command window:
F0 00 00 7E 40 00 01 00 00 20 00 F7 (PIC18F452, 32k)
or
F0 00 00 7E 40 00 01 00 00 40 00 F7 (PIC18F4620, 64k)
or
F0 00 00 7E 40 00 01 00 00 40 00 F7 (PIC18F4685, lower 64k)
F0 00 00 7E 40 00 21 00 00 20 00 F7 (PIC18F4685, upper 32k)
This command requests the internal flash content
o Start "Command Window->Send/Receive SysEx"
o the flash content will appear in the display window.
Save it (Display Window->Save as...) under the name "flash.syx"
o type one of these SysEx commands (depending on PIC derivative) into the command window:
F0 00 00 7E 40 00 01 20 00 00 20 F7 (PIC18F452, 1k)
or
F0 00 00 7E 40 00 01 20 00 01 00 F7 (PIC18F4620/PIC18F4685, 4k)
This command requests the internal EEPROM content
o Start "Command Window->Send/Receive SysEx"
o the EEPROM content will appear in the display window.
Save it (Display Window->Save as...) under the name "eeprom.syx"
o if a 32k BankStick is connected to your core, type
F0 00 00 7E 40 00 01 40 00 20 00 F7
into the command window
This command requests the content of the first BankStick (#0)
Use
F0 00 00 7E 40 00 01 40 00 40 00 F7
for a 64k BankStick
o Start "Command Window->Send/Receive SysEx"
o the BankStick content will appear in the display window.
Save it (Display Window->Save as...) under the name "bankstick_0.syx"
o if additional BankSticks are connected, do the same like above,
but change the BankStick ID (1-7) like shown here:
+--- BankStick ID
|
F0 00 00 7E 40 00 01 40 00 20 00 F7
F0 00 00 7E 40 00 11 40 00 20 00 F7
F0 00 00 7E 40 00 21 40 00 20 00 F7
F0 00 00 7E 40 00 31 40 00 20 00 F7
F0 00 00 7E 40 00 41 40 00 20 00 F7
F0 00 00 7E 40 00 51 40 00 20 00 F7
F0 00 00 7E 40 00 61 40 00 20 00 F7
F0 00 00 7E 40 00 71 40 00 20 00 F7
For 64k BankSticks use:
F0 00 00 7E 40 00 01 40 00 40 00 F7
F0 00 00 7E 40 00 11 40 00 40 00 F7
F0 00 00 7E 40 00 21 40 00 40 00 F7
F0 00 00 7E 40 00 31 40 00 40 00 F7
F0 00 00 7E 40 00 41 40 00 40 00 F7
F0 00 00 7E 40 00 51 40 00 40 00 F7
F0 00 00 7E 40 00 61 40 00 40 00 F7
F0 00 00 7E 40 00 71 40 00 40 00 F7
NOTE:
~~~~~
The core module will be reset after every read request. Wait
until MIOS has been booted before saving the next memory type.
Writing back the memory contents
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Just upload the files with MIDI-Ox
IMPORTANT: The delay between SysEx strings must be 750 mS!!!
MIDI-Ox: SysEx->Configure... -> set "Delay after F7" to 750 mS
If your sequencer supports receiving/sending SysEx
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You can just record and playback the received SysEx data
with a sequencer like Cubase or Logic
In this case, you don't need to take the "Delay after F7"
into account, as MIOS already delays the blocks during sending.
This method allows you to embedd the EEPROM or BankStick content
(e.g. MBSID patches, MBSEQ patterns) into a song.
Debugging
~~~~~~~~~
The MIOS release contains a syx2hex script which allows you
to descramble and to edit the SysEx strings.
