Okay, I'll try to make this as short as possible sweatdrop

So, I have an order for an Ar Tonelico OVA cover that I'm almost finished with, but I'm having a slight problem with the BPM. I think there's a slight increase (like, maybe from 102 - 105), and I've seen a VSQ that shows a change in BPM mid-song... how does one do that?
