How to: Song mode, chain mode with Elektron analog four

That’s a video I made also for myself to be able to remember how to use song mode and chain mode, which is combined, with this particular machine (Elektron analog four mk1). There is basically the same on mk1 and mk2 and analog rytm.
Maybe it’s useful for other people, too.
The song mode/chain mode (subfunction of song mode) has settings for mutes and transpose per step (take this oh MPC) :)
Please excuse bad English and pronunciation. I wasn’t in the mood to fire up the AI.
