How to move the arrows in a song?

I'm making an Applecore port of a song and I need to know how to change the position of the arrows in the song.

Songs that have unique gameplay features such as strumline movement have what we call "modcharts". They're coded in lua. Currently, LE uses Kade Engine's modchart system, so take a look here on how the basics of modcharts work. Definitely not enough for you to learn how to make modcharts off the top of your head, unless you're a god at figuring things out by yourself (but I mean, judging by the fact that this post is here I doubt it). I'd recommend looking up a tutorial on lua basics and then taking a look at the link I sent. It's in webarchive because apparently the modchart.md thing is gone, thank god someone archived it. Anyway, I hope this works or at least helps.
