I never used it and am wondering why it’s there. You are going to get timing issues because you are skipping steps. Maybe put trig mutes instead so you get all 16 steps in?[/quote]
Pattern offsets is one of my favourite features of the OT. I fact, I find it so useful I got angry when I received my a4 and realized it didn’t have it. Which means I have to sequence the a4 from the OT if I want to use offsets. Very annoying.

Back on topic, offset means the pattern will start playing from the step you select. So “8” will mean the pattern start playing on step 8. Length is for how many steps the pattern will play before jumping to the next row in the sequence.

Simple example:
Pattern A01: OF 0, LN 48 (a pattern with a straight beat)
Pattern A02: OF 48, LN 16 ( a pattern with a busy, crazy beat)
= a “full” 64 step pattern in total, but with a rhythmic variation or fill in the last sixteen steps.

You could do much more interesting things than this, though. I sometimes have a pattern running at 2/3 tempo and “insert” it here and there for a few steps to introduce rhytmic variations. For the fun of it I once made a pattern play backwards by setting a lot of rows with length 1 and decreasing offsets.
