I just tried it. Live recorded notes on the internal keyboard, then transposed as he did in the video, worked for me. Did you hold down a trig that already had a note on it when you transposed ?
I am on DT1, is this a DT2 feature? My problem remains and is the same for midi or audio tracks. If I do the note+track thing it just locks a note that’s transposed. If I do the page thing then it transposes the whole track, not only the page.
Any note I play on the keyboard is untransposable, I have checked the settings for any weird thing.
It is a DT2 feature … sorry, I should have taken account of this being an old thread.
They are pushing me into consumerism, fuck. Thanks a lot for the help. I wish they would shine one last ray of update to the old box 
Does octatrack have this 
Just so you know the DTII has the capability of transposing all notes on a track by holding a trig and TRK at the same time, and has the ability of transposing all notes on a page by holding Page and the trig at the same time.
However, it does not allow you to do this by octaves (what the thread starter was on about.) Because Elektron prevents the use of FUNC snap functionality when setting/editing trigs.
So be sure if you are buying the box you know the limitations of the current firmware and are happy with them before spending more money.
