These are some innovative ideas.  you guys always impress me.  Good stuff.
 
Thanks!!

Not sure how labor intensive this would be compared to what has been posted by others...but, I used to copy and paste my cymbal hi-hat hits in their entirety by creating about 4 measures or more of realistic actual velocity.  Tap on your desk or your thighs and pay attention how you emphasize *all* the notes.  I'd make as many measures of this velocity pattern slightly altered measure by measure, until it became too tedious, then copy and repeat paste that bad boy for the length of the song.  Then go back and throw in fill ins, cymbal hits, ride changes, stuff like that.  
 
Same with fill ins and everything else.  I always tapped it out so I could hear the subtle differences in velocity - not just the obvious emphasis on certain notes, but every single hit and the nature of human performance.  
 
But, honestly, no matter what you do it pretty much sounds like synth drums to me.  I can almost always tell.  If you're just wanting the drums to sound better, then these randomizing techniques are valid.  
 
 

There is a Cal script called VaryVel that excels at this: Select midi notes->go to process in the control bar->select cal scrips and choose VARYVEL from the menu. This should randomize the hits.

I still find myself using Frank's MIDI plugins for some of these kinds of things: http://www.midiplugins.com/Plugin/12

thanks all, I'm going to have a go at some of these suggestions and see what works out best...

I've spent a lot of time programming drums, listening/analyzing drums and talking to drummers over the years. Understanding their tendencies helps a lot to create realistic programming.
 
In this case, it is common for a drummer to hit the hat harder and open the hat to varying degrees when playing the kick and the snare. During a fill, or when the drummer moves to the ride... the hat "pedals" on quarters or eighth notes. Actually, sub consciously the drummer is always pedaling the hat... opening and closing it ever so slightly on each hit.
 
The hat is the timekeeper for most drummers... that is why it is continually going. It is also the item "most often on the beat" (aka, in time) while the snare actually drifts ahead and behind the beat depending on the feel. With dance music the kick is usually right on the beat, but in most other styles it drifts similar to the snare to create more feel.
 
There are exceptions to every rule, this is not meant to be a definitive approach - just a generalization.

Aside from adjusting the MIDI data, if you are using AD2, I suggest playing around with the hi-hat levels and effects.  I find that some of the AD2 presets have the hi-hat mic dry and mixed really high up while having it muted or low in the overhead and room mics.  This gives it a really artificial sound particularly when the snare has a reverb on it.  I have an electronic kit that I use for recording drum parts and still find the hi-hat sounds fake if I don't play around with it in AD2.  
 
I like turn down the hi-hat fader (or even mute it in some cases) and then up the hi-hat in the room and overheads.  I usually turn off the reverb in AD2 and then send the drums all to a reverb bus so all the kit pieces sound like they are actually in the same room and location in the mix.  

I've taken to using Jamstix to humanize MIDI drums these days. Given that you can give it your own MIDI patterns to apply "humanity" to, it really does work great for all styles, including electronica and EDM.

I use Vary Velocity and random time ( radomize with in about 4 ticks ) Cal scripts all the time with down loaded midi files. I also make sure my hat samples have plenty of velocity layers and add round robin between hats with slightly altered envelopes using battery. It's a very good representation of actual playing when I'm done with just a few key strokes.
