A few tricks I learned are as follows:
1) To add a slight bit of kick punch to a mix without really changing the sound, try boosting the EQ with a really tight Q at about 60-80HzHz. Not boosted too much, but maybe 2-4 db.
2) Feed the kick drum into the side-channel of a compressor you're using for the bass track/buss. With a 25ms release time, you can let the kick pump through the bass a good bit without the audible pumping of post-compression. Your ears have a natural compression release, where, when a loud kick hits, your ears should recover in about the same amount of time without detecting the drop in bass guitar or MIDI bass.
3) Waves Trans-X Wide. This is a very useful tool, but I recommend using it on a
copy of your kick drum track. On kick, I may also add Waves MaxxBass with some tweaking. It does ok. I don't recommend it for bass, though. For bass, I recommend the tape saturation or tube plug-in in the Pro-Channel to bring it out a bit without adding super-low-end. Subdue anything below 30-40Hz on bass, then boost tape or tube saturation. Light use of a limiter is fun, too, on bass.
4) Create a buss, called "Kick-punch". Add the Cakewalk TS-64 Transient Shaper to it. Set the output of that buss go to the Drums buss. Now, create a Send from the kick track(s) to this Kick-punch buss, and tweak the TS64 until you get the loudest, most ear-splitting punch from the kick. It takes some playing with. It doesn't have to sound good, you're only after the attack punch. You will adjust the amount to the real kick drum by adjusting the Send or the Kick-punch fader. This will
mix the TS64 with the rest of the kit, blending it in with the actual kick sound. I use this trick on snare with excellent pop!
5) Search your project and get rid of ANY ruble or kick bleed into any other drum mics, if it's really bassy. Sometimes, low-end rumble will eat up valuable space in the low-end when mixing/mastering.
