First of all — pick some songs and mix them. There's a lot of software you can use but I prefer FL Studio.
Copying & Pasting
1) Make another blank difficulty
2) Open up the map you want to copy patterns from. Delete everything (timing sections and notes) EXCEPT the notes you need to copy.
3) Save and open up the map in notepad.
4) Copy notes to the external difficulty you've made as said in 1).
5) Open up your external difficulty and place your notes where you need them. Add red section(s) for BPM as well.
6) Save and open up the external difficulty in notepad. Copy timing sections and notes to your original difficulty.
Adjusting slider speeds
1) Use slider speed of 2.0 in your compilation
2) Look up for slider speed in the map you're copying patterns from and add custom slider speeds.
Here's the list if custom speeds you need:
2.0 = no custom speed needed
1.9 = 0.95x
1.8 = 0.9x
1.7 = 0.85x
1.6 = 0.8x
1.5 = 0.75x
1.4 = 0.7x
... etc etc
*insert your cool storyboard here*
Submit your map and get a lot of stars and comments.
