If you want a device to fill the role of drum machine or sampler with some sort of song sequencing of patterns… Digitakt will just keep letting you down.
Sure, you can using the quick pattern sequence mode – but it is awkward. You can sequence the patterns from another device using program changes. You can even try the trick of routing MIDI out to in, but there are dragons there…
Even if you get pattern sequencing to work in your set up, the rest of the Digitakt isn’t designed for it: In particular, the sound kits are per pattern, and not shared - so if you tweak a sound in one of the patterns of a song, you’ll need to hand copy it to the others. The main mixer and compressor have the same issue.
In short - it isn’t set up to do this task.
