hey @P1505 - i’m also bummed about the missing “song mode” on digitakt. But i think you have 2 options.
1 - Call new patterns via midi from an external midi controller. I think the digitakt is looking for a “program change” message, and you send a numerical value that corresponds to the pattern you want to queue up.
2 - This one is kind of fun, it’s called “midi feedback”. You connect the digitakt midi output to the digitakt midi input, then you can sequence program change messages to itself. So if you had pattern “A” and on the last note of the pattern it sends a program change message corresponding to pattern “B”, then the digitakt will play pattern “B” next. It’s not a full song mode but can be an interesting way to work. Note that in order to make this work, you need to disable/enable some midi clock properties or the digitakt will get stuck trying to listen for the clock. There is more info on the in the electron forum.
