OK here is my situtaion, We recorded the drum tracks on a Mac using Garage Band, then I took the tracks (AIFF Files) and put them on my PC. I am using Cubase LE on a PC, I opened Cubase and created a new project, inserted all my new tracks then imported the drum tracks and everything loaded fine and played back fine. I recorded my bass track then sent the AIFF bass track back to my cousin that I got the drum tracks from and he inserted the track into Garage Band. When he played the song the drums started before the bass, why is this?. Another problem is I took all the drum tracks and my bass track and gave it to my guitarist on a memory stick and he loaded then on his PC using Cubase LE and everything played perfect. Now here is another problem. I recorded a new bass track for a song I already gave my guitarist and when he removed the original bass track and inserted the new bass track and payed it back the bass track started about a second after the drums started, what is going on here I am at a loss............
