You can remove content of protected cpf packs by unselecting the styles and registrations in YEM but indeed you cannot add content. So in this case, you have to create your own pack (using “create pack” in YEM) in which you add the renamed styles (and adapted registrations if needed). You can then combine both packs in one cpi file and you will find the styles/registrations on the keyboard in your own pack. I have done this for the downloaded packs for the SX700.
There is a much easier way.
1 Select the pack in YEM
2 You can then RENAME ANY file you wish directly within YEM
If you have already loaded the pack into your KB you can then save all the Registrations that refer to the Original Style Names and modify then.
4 Now copy these modified Registrations back to the YEM using "Import Content"
5 Then simply delete the original Registrations.
All Done
You can also use the MusicSoft Manager directly to your installed packs.
