Have you looked at the master transpose track? You can record transpositions into the master transpose track and have it transpose selected tracks.
Activate a track. 2nd+TRACK to enter settings. Activate transpose. Now this track will be transposed with the master transpose track. Create a new track. Set output to transpose. This track will now transpose. You can record notes onto this track. I think the root note default is C4. This can be change in the settings under “Transpose Note”.
PS. You can select all the notes in a pattern at the same time in step mode while holding REC. Rotate encoder 1 to transpose notes. Rotate encoder 2 o transpose notes, by octaves.
Hope this helps.
