Nightcore/daycore creating blocks

This project turns any song into nightcore, daycore, to the specified percentage, and you can evan add the song to sounds, where you can download it. There are no songs left in the project, or it wouldn't let me save it, but I have tested it with songs.
My nightcore/daycore project!

Why is the sample rate variable a block variable?

What? ^h ^h ^h ^h ^h Pardon, what do you mean?

You see I use sample rate 3 times?!

So I wished to abbreviate it rather that write it out in full. Three times.
