Hi Osbermusic,
Which YEM version are you using and which firmware version is installed on your SX900?
Please make sure you are using YEM V2.9.0 and that firmware V1.11 is installed on the SX900. To test I would then proceed as follows:
- Export the Instrument Info file (.n27) again from the SX900 to a USB stick.
- Delete the previous SX900 Install Target in the YEM and create a new Install Target by importing the new .n27 file.
- Click on the SX900 Install Target in YEM and select only ONE (relatively small) pack.
- Delete (on the computer) all previous Pack Install files from the USB stick used (file types .cpi, .ppi, .cqi, .pqi).
- Save a new Pack Install file of the selected pack on the USB stick in YEM. Before saving the Pack Install file, make sure you select the .cpi (or .ppi) file type (not .cqi/.pqi!).
- Try a Pack Installation of this file on the SX900.
Good luck!
Best regards,
Chris
