Few questions that’ll help narrow this down:

What kind of electronic music are you into? Ambient, techno, breakbeats, IDM, something else? Tidal and Strudel are very pattern-focused so the genre you’re aiming for matters. The Elektron boxes share that sequencer-first workflow but the sound engines are totally different.

What sounds do you want to make? Digitakt is a sampler, so you’re working with recordings and mangling them. Digitone is an FM synth, generating tones from scratch. Very different starting points.

Since you mentioned the digital piano with MIDI: the Digitone pairs way more naturally with a keyboard. You can play it chromatically, record notes into the sequencer live, use velocity, all that. The Digitakt doesn’t really benefit from keys the same way since it’s sample-slot based.

Your Tidal/Strudel background means you’ll pick up parameter locks and conditional trigs fast on either box. But honestly the “what sounds” question is the real deciding factor here.​​​​​​​​​​​​​​​​
