How to tailor an audio drum clip

What i did was recorded off of a multieffects pedal ,a short drum clip. Granted it starts out on beat but to have it end up exactly where it should end so that i can duplicate or repeat it is another thing for me. What i want is some help in figuring this out. The reason I’m doing this is because the MTPDK DRUMKIT plugin i have suddenly slowed up to take minutes to load.
The other thing is and i should have stated this before is that i am using Cubase Elements 10. The other thing is can I in Elements 10, can i change the tempo of the audio clip?

PROBLEM SOLVED
GOT THE MTPDK WORKING(BY LUCK)
