Hi , this is the answer from Ian of this group for me for the same topic, which would be helpful for you
Once you have installed your keyboard in the 'Install Target' part of the program's window using the 'Instrument Info' file, and imported some packs or content into the program, if you click on the target keyboard, the top of the screen will change to show the selected target keyboard ,and 'buttons' marked 'Save as Pack Install File' and 'Send to Instrument'
You can then select content from from each pack that you want to include in the install pack up to the maximum memory available on your keyboard.
You then use either the 'Save as Pack Install File' button to produce a PPI pack which is saved to a USB drive for transfer to the keyboard, or if you have your keyboard connected to the computer via a wireless network, you can create and send the pack to the keyboard using the 'Send to Instrument' button.
PDF versions of the YEM Owner's Manual and the Installation Guide are included in the download, so look out for them and refer to them as necessary.
