This is a kind of Fake Transpose using Digitakt Midi out to Digitone:
DN:
Pitch Bend Modulation Setup
Destination Syn: Pitch All
126
DT:
Set Pitch Bend Trigless Trigs (1 corresponds to 1 semitone)
Set different values and fire them with [Trig]+[Yes]
So you can hear the Pitch Bend of course, not sure if setting it up by Mod Wheel, Aftertouch or Breath minimizes the short glide…
