I feel that OB is going to make the DT more harmonious with Ableton. It’s just so capable- what I think OT has over DT is it’s ability as an FX processor(which, don’t get me wrong, it’s really fun to play around with and make the Fx portion of a track playable like an instrument-particularly with the scenes, but also with LFO)
But, DT sounds great with samples- will be able to “sample” via USB at some point which means a clip in your DAW can quickly be routed into the DT where it can be jammed on and recorded back into Ableton in an Arrangement.
That’s my logic and excitement for wanting a DT at some point- though OT mk 2 has a better USB port than the mk1 so MAYBE the OT really COULD be DTPro?
