Im back with another question. I have the OT since 1 1/2 years now… still clueless about so many things

So: I have a 64 steps pattern.
Scale Mode is set to: per track.
One of the tracks is only 48 steps long, so 3/4 of the whole pattern basically.

Problem: Instead of repeating after 48 steps (for some variation), it will play the first 16 steps TWICE, which adds up to 64 steps again, thus: no polyrhythm.

I guess theres just a little hidden box to tick somewhere, but I cant find it…

Sounds like maybe the master track length is set too low (16 or 32)? Try increasing it so that the track patterns have a chance to develop those syncopations before all of them restart.

set mater length to infinity, but then you lose pattern switching

set master length to the number when the start of your patterns will match again. In the above case the 48 pattern will loop 4 times while 64 pattern will loop 3 times. And so the master length should be 192. Science, biatch

you sir, are a genius!
I set the master length to infinity, so I dont have to do the maths every time I wanna do polyrhythms (I suck at maths). I dont lose pattern switching, my Chain Behaviour is set to 16/16, so I can change patterns after every 16 steps.
Or did you mean something else?

The math for polyrhythm repeat length is LCM of the step lengths (assuming same step resolution for all sequences).

so LCM(48,64) = 192. Google prime factoring for LCM to learn the manual process. The longer will repeat 192/64 = 3x and the shorter loop will repeat 192/48 = 4x.

Keep in mind, with weird big numbers, you can easily exceed max settable track length.

LCM(37,63) = 2331 steps

If you change patterns after 16 steps, then don’t you end up with a ‘glitch’?

Yeah… At PLEN settings, you can have your pattern repeat until the sun will become a red-giant star, and eventually leave a tiny white-dwarf star as a remnant. But that’s no issue really, as the Earth will have long disintegrated before the white-dwarf phase.
