Does the PSR S900 support the same linking functionality as the Genos and SX keyboards? If so, just select the Genos/SX600/700/900 option for the MIDI Device Type, and then you should be able to go to the MIDI tab in the song editor for a song and tap the link icon to link to the active registration. Otherwise if it does not have the linking functionality, you will need to set up the MIDI messages manually to trigger the loading of the registrations. You will have to determine if this will be done through Patch Select messages or system exclusive messages.

Thanks, I'll persevere a bit more, though a step by step would be nice.
I already have a program that will trigger PDFs from registrations, I was really looking forward to the reverse
