Not in front of my DAW at present but if you look in the track inspect clip tab there is a transpose function there.
My error if you look in the inspector for your midi track and click on the pro channel tab near the bottom is a window that says
Key+ To quote from the help
Key+. The number of half steps by which the notes in the track are transposed on playback (e.g., 12 to transpose up one octave)
