How do you use Digitakt for full-fledged productions?

Wait for OB or sell it, really the only choice for those of us that take our time crafting tracks from composition, to arranging, to tracking, to overdubs, to mix etc.

That said
In live you can use dummy clips to trigger pattern changes though. Any MIDI sequencer you can do this really. So make your own song mode using a DAW and try that. doesn’t help the tracking/mix stage unless you are a masochist and enjoy the track by track process.
