Every now and then, I get nice results from sidechaining the bassline to the kick drum using a high pass filter instead of a compressor. There are other ways to get this same sort of thing done, but this approach can yield a really interesting sound.

What’s nifty about this approach is that you’re filtering out low frequencies from the bass in response to the kick instead of changing the volume. The more you turn up Envelope, the more the cutoff frequency will rise in response to the kick attack. With higher values and a bit of resonance (Q), you can create more dramatic effects.

This works particularly well on big saw/square/distorted bass sounds with lots of high frequency content. You definitely get some of the pump of sidechain compression, but with all the nice high end crunch left alone.
