Tempos and sounds bugged

I'm currently rewriting a marching tenor part for the high school I teach at and I'm having tons of playback issues. I have the tempo set to quarter note = 160. The program will play it back at what seems to be 1 measure=160. The audio is also pitched up an insane amount. I am using the new Drumline plugin and have it set to play marching tenor drums in the mixer. any tips?
