Set an ADSR to modulate the frequency of a sine wave oscillator or self oscillating filter.Set the sustain parameter/EG amount/filter cut-off to tune the boom of your kick.
Set the fastest attack on the ADSR that is modulating the sine wave and the fastest attack you can get away with on the EG that controls the VCA, without getting clicks on the output (usually on analog synths).
The decay parameter on the EG that controls the frequency of the sine wave is what controls the sweep of the sine wave down to the frequency set by the sustain parameter/EG modulation amount.
The faster the decay the more tight and clickier the kick. The slower the decay the more old skool MWNN sort of sh-101, goa like the kick, where you can actually hear the frequency sweeping down.
EQ the region where you want to exaggerate the click of the kick and make sure you don't have a lot of sub in there, especially if you are planning on laying the kick on top of the bassline. But it's your choice really, subby kick, or subby basslines...but you can't have both occouring at the same time without using an awful lot of headroom.
Tune the kick using the method above so you can have a nice matching bassline-kick tone going on.
Compress the crap out of it. Use a slower attack on the comnpressor just enough to let the initial click transient to come through, but slam down on the body of kick and keep in nicely under control.
Use a gate to control the lenght of the boom to your BPM, or simply by adjusting the midi note lenght. Although it is best to record longer kicks than you will need and then simply gate the part you do not want out, instead of setting loop points to the tail of kick to stretch its "boom" to your BPM.
By adjusting the lenght of the kick and attack/release settings on your compressor so that the compressor barely goes out of the release state and the next kick occours, when a moment later the compressor starts working again you can get that nice "vacuum" kick effect, especially when you have a bit of tight reveb on it that has all the bottom end high passed on the returns, and only has the mid range of the reverb pasted on the tail of the kick.
Peace.
