mainly, with a tracker, you can import N samples (the more you have, the better will be the instrument) and give them a pitch, a volume envelope, a lot of other cool things. then you save the instrument as .xi (the native instrument format for FT2, also supported by MPT). Fruity Loops can import .xi samples, do you want to try? here is a lead I use often in my remixes: Right Click, Save As. Of course I'm not sending you a registered/copyrighted sample, it's just a shitty 8-bit one, just to let you see how it works. for what I know, you can import it in fruity loops. I'm not sure because I don't use FL, but it should work.for any info about importing/tuning/etc. the samples in FT2/MPT feel free to PM me.
