Another thing that is done in the studio is you aren't hearing 1 drum track ESPECIALLY the snare, almost all modern pop is layers of drums and virtually all of them are programmed. Example, I'll track up a song using something simple like EZ drummer or Superior drummer. I'll then copy that MIDI info to another track and drop a layer of Nepheton or some other TS-9 or early drum machine, then mix those together, usually making the TS9 a bit louder in the kick. Pull out most of the real sounding high hat and your start getting close. THEN layer in another snare sample or maybe some cheesy sounding thing from M Audio or dropzone. Jerk out most of the 'room' reverb and now you're cookin'. But wait theres more, add some super low end thud with the 4 on the floor kick, not a bunch just enough to make you say Lady Gaga BOOM, BOOM.
Next take your snare hits on the chorus (you can do this the whole song but it gets annoying) new set of tracks for this, and every other hit either do a reverse snare slide in, or add a really subtle clap, or BOTH. Now we're grooving pretty good but not there yet. There are some pretty slick sound modules that actually do what David originally asked about, PULSE along with the beat like bew bew bew bew most synth vst's have them. Slide one of those onto another set of tracks and mix it in really low, almost where you don't hear it at all. Figure 5-6 midi tracks just for drums. Thats the basics, it can be alot of fun to 'produce' music like this, but its a little ridiculous as well.
And this is why famous bands, DJ's ect all have to run tracks if they want to be even close to the recorded sound. Frankly I find acts like P!NK and some of the Rhianna I've seen live to be much more enjoyable when they just play instruments and create a live band sound, not really go after the recorded sound. Its different, I've heard the recording, if I wanted that live I'd just yell at them to play the CD.
