This thread inspired me to dig into the Arranger mode on the OT. The manual is definitely your friend here, along with a few quick test arrangements / experiments. A couple of hours will make sense of it all. Well worth it, helps you think more about structure and not just pattern to pattern playing.

The most complex part is certainly the Offset & Length parameters but that’s more on a conceptual level. The explanation above is clear though… offset is where in a pattern song mode plays from and length is how many steps will then play. You then use Rep to repeat that a number of times if desired.

So if Offset was 8, Len 8 and Rep 4 then steps 8 - 16 would play 4 times before moving on. The only bit I don’t understand is why Length can only be a minimum of 2 (so no single step repeats) but this seems to be a limitation of the OT sequencer overall (ie: you can’t set a Track length to be 1 beat either… It always has to be 2).

The mutes LEDs not updating is kinda odd but at the same time since you can override the Arranger and mute tracks manually above what the Arranger mutes. So the LEDs reflect your manual muting decisions. A half lit LED would have been nice though.

After playing with the Arranger for the afternoon this video now makes a lot more sense and it shows what you can do creatively with the Arranger (it’s MD but it’s essentially the same as the OT)
