I seem to be the only one I know that does this, but I write the entire drum parts in the piano roll of my DAW. I audition parts in EZD/SD3, but then drag the MIDI's directly to my piano roll. It just seemed to work faster for me that way and it's a hell of a lot easier to adjust the velocities in the piano roll. Essentially, I use either program as a sound module for the kit sounds only and then to sort through fills. I write 90% of my drum tracks and only pull from the fills when I'm being lazy and don't want to program them.
One thing I wish I learned early on is that for the kit to sound more realistic, you really need to pay attention to the velocities. Look at some of the supplied MIDI's to see what they look like. If you want a robotic drum sound, just peg everything at 127 and call it a day. I've found the kicks sound best at 118-122 so you're not burying the beater in the head (the drum resonates more when the beater hits it then bounces away from it, burying the beater keeps the beater on the head after you hit it). Snares I'll usually keep around 124 until a chorus, then I'll get them all at 127 (except for fills).
I don't know if Reaper has this function, but in Logic, I can select a large amount of MIDI notes and randomize the velocities. So if I have a section where it's straight 16th's on the kick drums, I'll randomize it to 118-122, then go back and set all the downbeats to 122. The thinking behind that is actual drummers tend to lay into downbeats a little harder. Sometimes I slide shit off the grid a bit to make it a bit more human, like the end of a fill I might rush a tiny bit just to give it more excitement (without sounding like a beginner drummer).
I used EZD2 for about 4 years before upgrading, it definitely gets the job done. Programming drums is the least amount of fun to be had when writing, but it's one of the biggest payoffs when the drums come out sounding great and they work with your song well. You can always point out when someone just dragged a bunch of fills or didn't write their own drum parts.
Oh, you can also write a drum section in your DAW, export it from the DAW and load it into EZD's MIDI bank, so you'll be able to use it in the future. I did this for a few standard beats I use all the time and it's come in handy quite often.
