I see. So the .wav samples are only stored on the Expansion memory.
-exactly!
Will making a Custom Pack in YEM allow for different sounds from different packs to be stored on one user pack?
If you only have (unlocked) *.ppf packs, then you can create new empty pack (name it to your liking) and then you import content from multiple ppf packs into your custom pack. After importing each ppf pack, you can delete unwanted content (voices, styles, registrations, etc). In short: you end up with one install pack which contains only one pack.
If you have locked (*.cpf) pack, then you can't import it
into your custom pack. However when you create install pack, you can check everything in your custom pack, plus desired content in one or more cpf packs. In short: you end up with one install pack which contains multiple packs -these will be shown as folders on keyboard.
Btw. you can do that with ppf packs as well.
How many sounds can fit on a pack?
The size of install pack is limited by amount of expansion memory that your keyboard has.
