Thanks Chris. I've learned something new today 
So the only way to get this PFF voice on the keyboard is to import into YEM, save, and then load (along with all other packs) into the keyboard?
I assume after doing all that, the PFF file will then be available in the keyboard voice selection?
Would it not be a lot easier to just create a .vce or similar file ? Not sure of the advantage of a PFF voice file
Hi Larry,
you can import a .ppf Pack file into the YEM using "My Packs > Import Pack", or ceate a new, empty Pack (or use an existing, unprotected Pack) and select "Import Content" inside this Pack.
Then double-click on the desired Voice to open the Voice Editor. Make sure that your PC speakers are selected for the YEM Sound output. Then you can play the voice using the virtual keyboard.
To close the Voice Editor window click "Back". I you should have accidentally changed something, be sure NOT to click "Save" but always click "Discard".
In order to use the voices
on the keyboard, you must of course run a Pack Installation (either via USB stick or via WiFi). It is important that ALL Packs/contents that you want to have on the keyboard are selected in YEM.
P.S.
Using the YEM is the only way to make new Voices that are based on new Samples. A Voice Set file (e.g. .vce) only contains edited Voice Set parameters (and use the samples of the corresponding Preset Voice).
Best regards,
Chris
