dc offset problems can occur for a number of reasons. If you have a sample that is shifted - there's the problem. However, you might check all of your samples and see nothing wrong with them individually - leaving you puzzled. You may be playing back a sample at a very very high speed - or a very very low speed. Doing this can often do weird things to the DC offset. If you're using samples from vinyl, be sure to check them as very low frequencies can show up and cause similar DC-offset related problems. In fruityloops, if you solo each track and look at it in the waveform display, it should be easy to see which one is causing problems. Its difficult to explain, but once you see it, you'll think "oh, weird". Usually, filtering out the bass frequencies on whatever channel is giving you the dc offset problem is a good solution - unless your bass sample is causing the problem in the first place, in which case you probably need to re-think what you're trying to do w/the bass. Its the really really low bass frequencies that cause problems, so using highpass filters set at 30hz or wherever your desired bass drops out could do the trick.
