Another option is to use Jamstix, which isn't based on pre-recorded MIDI loops and you can use it to generate quite realistic sounding fills. It has a lot of control over how to generate the fills, from super simple to over the top complex, based on "players" modeled after famous drummers. You can also use Jamstix to drive your favorite drum VSTi, or use the generated MIDI as a clip somewhere else.

In some aspect, I'll use drum fills in Toontrack, only because I'm not a drummer, wouldn't necessarily think of that pattern to program on my own and am relying on the expertise of the creator of the MIDI fills.  Then you can tweak them to land where you want, cymbals, etc.  Using MIDI triggers, many fills I'd never be able to play as well.
That said, I could care less if a drum fill revels that the *drummer* has 3+ arms banging away.  It's the end result.
 
I can say the same for just general grooves as well.  Lots of times I'll hear something that will give some extra inspiration.  No different than puking on your keyboard with Omnisphere, and digging the sounds.

another option for grabbing fills for the non-drummer is to download one of the endless midi files of songs in existence and just copy and paste the section with the desired fill.  As with any midi file, you can alter it .  Jungle/drum and bass artists have taken the same Amen break and made tens of thousands of songs from it.  I treat any premade loop whether audio or midi like a sculptor would treat a piece of marble.  You can leave it as is and have a nice block or you can start carving and create something that only you can.

Thank you for your support and replies. Drums are not something I enjoy programming. It is very time consuming and boring at the same time (to me). I have electronic drum kit (Roland V-Concert- the blue set). I have local guys come over and record drums for me, but lately I have been busy with school and had no time to maintain a drummer. While I can program simple fill, the point is- if something is for sale- it implies that it is for me to use. I am not happy about the fact that I bought it and then I have to make my own. The fill should start on 1 and if it does not play on 1, have some kind of place holder, so that when I insert it on 1, it plays where it meant to be. If the fill does not start on 1 and I insert it on 1, it plays some "blub dig boop", then I would have no way to know what that person meant because I don't know where it fits in the measure. With the grid on, it falls on one of 16th notes, without grid- it can be inserted anywhere and it does not even ends on 4 or 1.
 
My music is very tolerant. It has no style. The song I was working on mixes groovy rap/hip-hop beat at 80 bpm, with orchestral, opera, dub step, trance and metal guitars. Any fill should fit in, if the fill is 1 measure or 2 measures. If the fill is 2/3 of a measure and it is not logical, I don't know where to insert it. All I am saying is- how hard is it to ask a drummer to play square 1 measure fills? The reason I can not program it myself is because my drum track is set with Maschine (and my midi controller is weighted key action). I do not know how to use Maschine pads to control non-Maschine plugin. For example, if I wanted to use pads of Maschine to trigger Sessional Drummer- it wont do it. It probably will in Controller mode.... The point is- I went through all libraries that came with SD and other libraries that I had as expansions, and none of the fills would work. And then the workflow on the Sessional Drummer: there is no way to audition the loops without actually inserting them in to the Loops section. There is no "Next" button, so you can not go from one loop to another by clicking next- you have to open a file window every time. Also if you on loops starting with "M", such as "Monkey Jam", and you want to open new one again- it jumps back to "A", so you have to go look for the one you just inserted to replace it with next one. That is very time consuming. Now loops in Sonar browser were silent- they would not audition trough Sessional Drummer. Then if I double-click on a loop, for some reason, it inserts at least 5 loops on 5 tracks below the Sessional drummer, and even if it is violin audio track, it throws some kind of loop on it, which I obviously can not hear. What in the world is it?     

I think youre overcomplicating things, you do realize that editing and creating your own drum loops is easier than just about anything else you can do on this software using the piano roll view? You don't need a midi controller to do this. The first day I downloaded X3, I looked up the session drummer tutorials and was instantly creating my own drum loops with ease. If I can do it with no effort then surely you can manage as well.

Your next project should be, get to learn how to use Maschine inside out. If you've got one of these use it!!! Good Lord man!!
I have one as well but I haven't really got around to it properly, I definitely will once Groove updates their tutorials to version 2 (just around the corner so I'm told)...

BTW I can trigger Addictive drums or session drummer easily in Maschine controller mode.

this is no joke. rail's platinum samples are top notch stuff.
we received a complimentary sample pack with the content club last year with the purchase of sonar x2 and I love them.
 
about session drummers included content, there sample pack loops from smart loops, exc.
smart loops are not the worst ive heard.
 
I don't use them personally, I create all my own beats and fills.
IMO its about originality, creating my own things, I don't feel comfortable using other peoples creations.
that's not to say its a bad thing, that's only my opinion.
I only use the included SD3 midi loops for previewing my kits when im building them.
 
though I am warming up to addictive drums and realize its power over SD3, I become fond of session drummer for its simplicity. its so simple to set up each drum to each track and apply effects.
even now when im in a bind recording a live kit, if the kick is not consistant, I will sample a kick and create an SFZ file, drag/drop it right in to SD3 and start layering.

I made this Video, its called editing drums in the PRV.
check I out.

not time consuming at all.
build a routine, if your not using the piano roll in sonar, then you are missing out on one of sonars best tools in my opinion.

You can preview MID grooves from the Browser window in Sonar... Where you can easily switch between files to preview
