Screenshots 11 and 12 show the MIDI exclusive commands of memory 10 in the situation that link is o.k. In the case that link is not o.k. I cannot show this because the MSsheetmusic is not displayed.

The sheet does not have to be displayed by pressing the button. You can manually load the sheet and then take a screencapture of its MIDI commands.
The MIDI commands Mike is asking for are stored when making the link with Genos. They will not change unless someone changes them, or when a new link for that same song is created.

Having said that ... what is the smallest number of registration buttons in use, that can cause this problem? If it is possible to create a registration file, with only two working buttons, where adding/linking a third one will break the link for the first two buttons ?? If so, it may be easier to take pictures of the MIDI commands that are stored with the songs linked to that registration file, as there will only be 3 songs not 10 to take screenshots from ....
Just my two cents...
