I didn't snap inherited sections because it's pointless and a huge waste of time.
I did fix the problem in Larto's difficulty though, just copy this and all the sliders fix themselves (don't put this in any other difficulties):

Also apparently the taiko difficulty is just a copy of Larto's sections that don't do anything in taiko, plus one speed change (wat). Just replace with this:
Also drums sound fine at 30-45s. If it's off it's like 2ms
