I have a problem where if I have heavy bass or a bass drop it pulls the volume of everything else down. It almost sounds like it's pulsing. Can someone please help me understand how to fix this and have heavy bass without causing everything else to pull down? I thought I had everything eq'd and compressed decently, but I guess not. I'm using FL Studio so if you could recommend stuff that is already in there or free plugins that work better it'd be greatly appreciated. Thanks in advance!

I don't think my volume level is necessarily the issue. It doesn't seem to affect the drop or anywhere else I have the sub bass. Only where I have the single shot it seems to draw the levels of the rest of the sounds down. As far as the bass drop I'm referring to it's just a bass drop sample that you'd put after a drop or something so when I have that hit it draws the level of my down lifter down and when the sample finishes the volume level of the down lifter rises back up. I don't have the volume levels cranked

I can't decipher what you're talking about. The terminology isn't any thing common or useful :|

What is a down lifter? and how does it go down? and in what context does it go down?

It still smells like that particular "down lifter" is to loud and causing some thing to activate like a limiter or a compressor (don't mix into those things if you have them on your master buss; i also wouldn't recommend mixing into them on a channel either, because if you don't know how it behaves, you could end up getting that pump, and not in the way arnold means it)

If you can come up with better words to describe your situation, maybe i can help some more.

But i'd suggest what wontolla says and see if that does the trick.

The problem is with a conflict of all of your low end elements. At that "instant" on the first beat of your drop. You have (I'm assuming) Kick, sidechained bass, "sub drop/downlifter", and other assorted downshifters (while even though they might be white noise they still have a ton of low end energy).

Some tips:
Put a very small fade in on the first kick beat. It will allow the transients of your impacts and downshifters to come through on that first beat. This is done by a lot of prog producers including Jay Hardway, Volt and state, Manse etc...

High pass the white noise downshifters to get the low end out of their samples out of the way.

Make sure your Sub and bass are sidechained hard enough so that they are not conflicting with the kick.

Add a sidechain/lfotool/volumeshaper to your downshifters.

Just tossing out an idea...

Could it be a frequency clash? He stated it is on that specific hit, and all I could think is that certain frequencies are cancelling others out possibly.
