The file(s) you are looking for are all in the wiki, and accessible. Hope this helps!

Ahh, I see. Is it this one?
Yes, thank you very much. 
I think the manual page needs to be updated, now it links to http://ucapps.de/midibox_sid_cs/mbsidv2_front.fpd , while the correct one is http://ucapps.de/midibox_sid/mbsidv2_front.fpd
