Hmm, so I'm just working on some time signature features and I stumbled upon this bug in 3.1 that might be useful to some for experimenting. Maybe someone has posted this before, I don't recall seeing a post about it.
If you want to place a pattern and have it NOT aligned to the measure line, first switch to pianoroll view in the sequencer, then touch the note icon between the two zoom icons. De-select "Q.tize" on the right, then select some note zoom value to make the menu go back to normal.
Now if you switch back to pattern view, you can move your pattern and it will respect the "don't quantize" feature of the pianoroll, allowing you to place it at a delay. You can use this to repeat a pattern to odd values like 1.5x, but you can't go smaller than 1 measure. Overlapped patterns are also possible and while the app gives an error, it still plays fine, just cuts off the old measure to play the new one.
Just remember to set quantize back on when you're done messing around.
