Hi hoppysheba,
It's been a while since I last saw you on the forum. Welcome back

As Matt and Lloyd have indicated, there are some things that can be tried that might do the job. In addition to what's already been mentioned, here are some other thoughts that might be useful.
Find a particular set of Realdrums that you like and use that in all songs.To find potential Realdrums that will be suitable, have a look at the image below and follow the instructions 1 - 5.

1. Right-click on the Realdrum name in the mixer.
2. Select (i.e. left-click) on "Realdrums in style" (#2 on image). This will open Realdrum picker.
3. In Realdrum picker, left-click on the "Genre" column I've highlighted so that the genre's are sorted in alphabetical order.
4. Scroll down to "Jazz" (#4).
5. One by one, click on each of the Realdrums and then use the preview buttons (#5) at the bottom of the Realdrum picker window to hear how the drums sound. When you find a drum set that you like, write it down and then manually load it in each of your song creations.
Investigate styles using time-base settings.6. Down the bottom of Realdrum picker, there's a time-base setting. Experiment with this. I suspect that by setting the time-base to 'half-time' and then exiting to your song, you might find something that does the job.

Note: After changing the time-base, it's necessary to regenerate the song when you return to the chord sheet. (Also unfreeze the drum track prior to generating if it's frozen.)
Regards,
Noel
