Session Drummer 3 randomly skips notes

Hello Cakewalk land,
 
I am new to using soft synths but I love Session drummer 3. My issue doesn't seem to be addressed here in the forums (or at least I can't find it). When I playback my drum parts some notes are not played. If I stop and restart near that measure it will play it. If I delete the note and re insert it, still the same issue. I'm positive it has to be a setting related issue where the midi note isn't being recognized or my Korg isn't responding quick enough and the note doesn't get played but I can't figure it out. Any suggestions would be fantastic.
 
Thanks
