Thanks for a thorough +/—walkthrough! 
My hopes with it is to use it as a more “one-box-only”.
But I’m not sure how easy the Rytm is to make melodic sequences?
With the DT you just push [FUNC] + [TRK] to reach chromatic mode and you can also choose in what scale to play, is this somewhat similar?
How direct is the sampling on the Rytm compared to the DT?
