You have to begin your code with a number between 1-400 for your BPM then put L's and R's and U's and D's in whatever order then end with a slash (/) or it won't work. Make sure your letters are capital or they won't be read. Set your speed to whatever you want and enjoy! P.S: You can also put E's if you want the song to wait for a bit.
Proud's one is much better than this bcs of more customizability plus this one is a lot more buggy I only put it together in a week but this is much easier to work with especially with making your own codes without the need for a beatmapper. But if we could rework a beatmapper to this system with the addition of held notes it would be good. just a test tho, the neofunk team probs have something in mind.
