MaxxBass and Sidechaining

I've only used it a little but i couldn't get any results from it that i really liked.
Felt like it'd be more beneficial on processing bass for rock bands or shit intended for playback on computer speakers or something.
If you're producing something to be played in a club i think a balanced mix is an easier way to get solid weight in the low end.
Especially if your basslines are sine's with other layers on top

That said I'm sure if you spent long enough with it you would find a method that would work for club systems
