Excellent - that's good;) I was asking because I wasn't sure whether you are using some sort of recent version or a really old one, where there was no limiter on master channel by default.
Got a little excercise for you: I had this sort of quality / compression issues (especially while trying to "pump it up") and then someone told me to do this (it was a MASSIVE eye-opener for me):
1) Create a new project, you should end up with the basic fl "dancy" drums (kick, clap, hat, snare), leave everything default
2) On your Pattern 1 enter the most basic kick drum beat, a simple 1-2-3-4, not the slightest variation, just basic
3) Max the volume of your kick drum using the knob on step sequencer
4) On the very same Pattern 1 insert a new channel - 3 Osc
5) All 3 Osc shapes will be set to Sine - first one on the left. Change all of them to the square one (third one from the left, like a horizontal squary "S")
6) Go to the 3 Osc piano roll and insert one C3 note, just one note, spreading across the whole bar
7) Click play and listen to the pattern
8) Now then... Add Fruity Compressor to kick drum mixer channel (should be 1 by default).
9) Choose 'Brickwall' preset on the compressor
10) Play pattern 1 again
Compare what sort of difference switching this compressor on / off makes. And there you go
Next step would be to try to create an actual song with this setup. Try to keep the pump while layering it up with more stuff - don't compress anything else. This approach is somewhat limiting, as in it won't fit every style, but it should hopefully get you started big time.
Also, when you feel you need to add some bass on your EQ.... substract some mid / high instead
