So, is the Bosendorfer piano already preloaded onto the Montage or is it a library of some sort that must be uploaded in order to be used? Such a beautiful sound.
Think I found my answer here, already replied to in a previous post response to another forum member:
Place the drive with the unzipped file in the TO DEVICE port.
Press [UTILITY]
Select "Contents" > select "Load" > there should be box representing your USB drive, touch it to open it
set CONTENT TYPE = "Library File"
Find the "Bosendorfer.X7L" file, touch it.The LIBRARY file does NOT overwrite what is your Montage's current USER memory. It installs this file directly to the Read Only Memory area of the Flash.
