Hello! I've been looking for around a year now for a mod that changes the tickrate of a world like this mod here! https://www.curseforge.com/minecraft/mc-mods/tickratechanger
I use this mod to make noteblock songs for my youtube channel and I really want to use 1.14 noteblock sounds. The problem is I have no experience in updating mods and making mods and I would LOVE to either update this mod or make a totally new mod with the same properties of the previous mod.
Yea everyones told me that LOL but the problem with that is, it doesn't slow down or speed up the whole server. It only does it to entities and how the world develops. The mod I use makes it so redstone is effected also so I can make my noteblock songs the speed they need to be. Hope that helps!
