Tony,

Yesterday you piqued my interest in having my Android Pro12 tablet change Songbook entries and the Songbook entries working in reverse changing what lead/vocal sheets appear on the tablet. On the Pro12 there is a USB port with with a USB cable one end plugs into the tablet and the other end plugs into the back of the board in the port labeled " device". You do not use the midi in, out or thru connections or do you use the host USB connections on front and back of the board.

With that said I downloaded the manual on the how to and played around with it today, it's a straight forward process and works well. I configured it for a dozen tunes today to work and it's flawless. The only caveat is I have 512 tunes loaded in Songbook, not so sure I want to take the time to convert them all.
