Exporting audio in Reaper

[chinnybob]

Hey everyone,

Got a complete novice problem for you! So I've been recording with Reason for ages and been pretty happy with it, but I could never get a great drum sound out of it so I impulsively bough Superior Drummer and downloaded Reaper.

My problem is that when I render audio from Reaper and then listen to it in itunes or whatever, it sounds completely different. When I play stuff back in Reaper it all sounds fine, granted I'm not fantastic at mixing and all that, but after exporting the bass seems to get turned up on everything, which especially makes the kick drum unbearable and the whole thing starts clipping.

Literally no idea what's going on, any ideas??
