Toby Fox once wrote a tutorial for FL Studio all the way back in 2011! Even if you don’t intend to use FL, it’s still a pretty great read. https://web.archive.org/web/20111108213156/http://tobyfox.net/Tutorials/FLBasicTutorial.html
"You can get the Mega Man X soundfont for free here! It is by Dave Harris.
After two months of work, I've finally finished my cover/arrangement of Alright by Maxton Waller! I love Dndads so much, and I decided to culminate that in a medium that expresses me most. I am really happy with the end product, and I hope you enjoy listening to it :)
