So, I wanted to make a Triple Trouble cover with my four mains in a Pokemon Fighting game I play (Pokken Tournament DX if you must know. It's a lot of fun, 10/10 recommend if you like Tekken and Pokemon!). I plan on making different chromatics for each character. I have Lucario, Machamp, Mewtwo and Shadow Mewtwo. I also have no idea how to use FL Studio. Like, at all. So I have a few questions: 1) how can i make the chromatics sound different without using different people? 2) how should i go about getting the vocal lines and instrumentals? are they on MarStarBro's twitter thingy? 3) how do i cover the song? (if this can be answered as simply as possible, i'd appreciate it, im dumb af) 4) do i need to get permission to upload my cover to youtube? thanks in advance!
