To do so we need to figure out reply formatting of command querying preset.
|
|
amidi --port=hw:1,0,0 --send-hex F0 00 00 10 00 5E 02 2a 00 04 00 62 F7 --receive=preset
|
|
will create file named preset (give a while for it, and then hit ctrl+c)
|
|
this file should have around 440 bytes (depends on actual preset)
|
|
0x21 byte holds amount of options
|
|
from 0x22 byte starts effects configuration which is:
|
|
-2 bytes for ID
|
|
-1 byte for position
|
|
-1 to 3 bytes for value
|
|
Each 8th byte (beginning from 0x27) seems to be status byte which describes
|
|
whether or not we shall add 0x80 to ID or value and whether or not value
|
|
will be multibyte. So far I couldn't figure the exact meaning of those bytes.
|
|
To check you can download some patch from DigiTech Sound Community, apply
|
|
it to your device, and then do this amidi command.
|
|
Open resulting file in hex editor, and open patch file in text editor.
|
|
Every ID, position and value found in patch will appear in the binary file.

-fix expression pedal settings (possible types depend on active effects)
