Hi Matthias,

To upload a file, all you have to do is, after you open a message window, click on "File Manager" as in the uploaded screenshot below. If you have an issue, let me know. I will PM you.



Now, what file are you referring to? I was wondering if you would share your MIDI Designer layout/file. Once I have that, I will go from there and incorporate a foot controller.

You said, "because I can only use Sysex for existing buttons." As you probably know, there are many other functions in the SD40 that you can call up by sysEx. So I was thinking that once I receive your MIDI Designer layout, I can just enter any sysEx I want.
