Reaper - General Help

[Kain Nobel]

(I'm changing the topic title to "Reaper - General Help", as I'll probably be asking further questions when the need arises.)

Alright, the input monitoring is probably as good as I'm going to get, I suppose I can work with it from here. There is still a bit of delay, but the tone it outputs is relatively clear, so as long as I play it as low background noise while I'm recording, I have an idea if I'm in the 'sweet spot' or not.

I do have another question though! :D

I've made a couple backing tracks in another software, some drum and bass and such, which I would like to record over, how do I do that? I'm aware that you can make your own 'beats' in Reaper somehow (I haven't gotten around to that), but for now I'm making them in FL Studio since I'm efficient with that program lol. Anyways, I want to take my FL tracks, render them to mp3 or wav or whatever, and jam over them.
