Once I got frustrated over the small buttons on the module enough to 
chart out the contents of a user kit syx file. So it's not encoded. 
The file has distinct blocks of data for every pad and so on.

Finding out the structure of the file was quite a pain in the butt 
though, fiddling with a kit parameter and dumping the file to a 
computer to check out with a hex editor which byte has changed. I got 
it charted out pretty nicely though, except that there's this one 
byte that just changes between 0 and 1 and doesn't seem to represent 
any real setting. Oh well... :) 

And as every parameter except the kit name is just a numerical value 
it was at times a bit puzzling to connect it with the setting value 
that's visible on the module.

Didn't get around to coding a software for it yet though.
