Hi Drsun19,
When you press a Registration button on the Genos, a unique SysEx string is sent via MIDI / USB-MIDI. You should be able to record this SysEx message with Camelot's MIDI Learn function and link it to the corresponding scene/song (to which the relevant PDF file is linked). When loading the registration on the Genos, the relevant scene/song should be loaded in Camelot Pro and the linked PDF should be displayed. Conversely, when you select a specific scene/song in Camelot Pro, the relevant registration should be loaded automatically on the Genos.
By the way, in the iOS app "Songbook+" there is a special link function, with which a "song" can be linked to the currently loaded registration on the Genos with one click, and this link then works automatically in both directions. In principle, however, this can be achieved with any suitable app that has a MIDI learn function (that supports SysEx) and in which the recorded SysEx message can be linked to a "song" (for MIDI transmit and/or receive, such as described above for Camelot Pro).
Hope this helps!
Best regards,
Chris
