I have no idea how to write 32nd notes and faster in step write, from what I can tell it’s just 16th notes.

not sure how or if you can write single notes 32nds - but you can write in re-trig notes at 32nds and have them play 32nd speed instead of 16th which is pretty great

There’s micro timing where you shift the trgs further left or right by pressing a trig and Left or Right.

Hold function and the bottom right key to increase pattern bar length. And while in that menu change the multiplier to x2.
