Hi Joe H,
I would welcome any feedback about this procedure, because as I said, although I can make '.cpf' packs specific for the instrument info files that I have, I have not really got a way of checking them, other than loading them back into YEM, but since this has those instruments installed as target keyboards, it would work wouldn't it! I suppose that I could make a pack for one of them, then delete that instrument as a target in YEM, and then try to import the 'protected' pack.
Edit: In fact I have just tried this for a pack that I exported protected for the S970 that was installed as a target in YEM when the pack was exported. I deleted the S970 from YEM and tried to import the pack. The program responded with a message box saying "The pack could not be imported because there is no instrument capable of using this pack". I then reinstalled the S970 as a target and tried to import the 'cpf' pack and it reported that a pack of the same name already existed so could not import it! So I deleted the original pack in YEM and then the program successfully imported the 'cpf' one. When I open the imported pack in YEM's contents window, it now shows with a padlock in the header, which I think means that it is a protected pack! As an additional check, I made an installation pack of the file after re-importing it into YEM and that produced a 'cpi' file according to the file extension! However unless I selected the correct S970 target, I couldn't even select the protected 'cpf' from the installed packs window to select to include it in an installation file. If either the T5 or the S670 that are also installed in YEM as targets was selected, there was no 'tick' ['checkmark'] at all in the pack icon
If you have read the relevant part of the YEM manual, you should have seen the following note (on page 9):
"NOTE
You cannot use Export Pack, Change Image, or Rename with protected Packs, such as any that you have purchased."
The '.cpf' pack that you purchased (for a Tyros5!) would probably have the same problems for you today if you tried to make either an installation or a project file pack for a different keyboard! How did you even manage to purchase a Premium Pack for a Tyros5 without having registered a T5 with Yamaha Musicsoft?
Please check the situation out and report back, just out of curiosity/interest from my point of view, because currently I have no intention of replacing my T4 with a T5, and I don't need a PSR, so YEM is somewhat academic for me.
Regards
Ian
