Jim:
If you have different song names in each of your 10 buttons x 100 banks, there is a way with YRM 5.1 Special to do exactly what you're looking for.
Put all your registration banks in a single directory.
Open YRM and set the target keyboard to Genos.
Click the button Duplicate/Remove Bank Settings
There is a option in the first pane, Export Buttons to Banks, check this and Ok
Check All Buttons in the next pane and Ok.
Click the Button Export Buttons to Banks and select the folder containing your 100 banks, then select or create a folder for the new 1,000 banks.
When that has finished, click the button on the Main screen, Play List Editor.
Click the button New Play List
Click the button Open Banks, and select the folder containing your 1,000 new registration banks.
In the next box you'll need to identify where these banks will be stored on your Genos. You can edit the folder name before you click the Ok.
Click the First record, scroll to the bottom of the box and Shift Click the last record, all will be highlighted.
Click the Add Item button and all will be added to the playlist.
Click Save Playlist and choose a name, and you're done.
While you're in the Play List Editor, you can sort, move items around, change the name of an item or search the list (needs at least 3 characters for the search).
Hope you have access to a PC now, cause this is a piece of cake.
Cheers,
Murray
