Hello!
Only recently I found out [that I like a lot listening to] Jan Jelinek’s music.
If I had to create something similar, I’d have no clue!
Perhaps my favourite is “Them, Their”.
Understandably, I do not find many tutorials for this kind of music.
I am sure he uses plenty of gorgeous gear 
but I’d like to ask you: if you had to choose one Elektron box, and only one, which would you choose to recreate the gist of his music?
Octatrack.
Jan Jelinek is “important” in the history of the music for the innovative use of samples. So, I think that DT, OT and AR are machines that can help you to make “similar” music.
Absolutely love JJ. He uses a lot of different time signatures as well.
I’ve seen him also use a lot of modular.
Here is a decent vibe similar to his on the OT:
He also has some aliases - Farben and The Exposures are two that I’m aware of.
