Ok I have an orchestral sample taken from a big piece of music. I dont know the name of the piece, I dont know what key it is in and most importantly, this means i have no idea how to write a bassline/melody/whatever if I was going to us the sample as part of my tune. How do I find what key its in to then make a bassline/melody/whatever. Or alternatively, is there a way that I can change the sample from whatever it is to a key of my choice? Im working with FL Studio 7 Thanks people!
