I don’t own a Digitone so I can’t compare but the Digitakt has a pretty cool MIDI sequencer! You can record a polyphonic sequence from an external keyboard in real-time, quantized or unquantized. You can also hold a trig and play the note/chord that you want to assign, so yeah I would say it’s pretty powerful and flexible!
I do experience some inconsistencies though, when I record something live it tends to miss some notes, but I didn’t find any similar stories on the interweb so I might be doing something wrong.
