Help! Audio files move when changing tempo track

Hello Studio Forums!


I have a rather tricky problem. I was and recorded the drums to a disc for a while (Band: Age of Glory) in Cubase 5 I recorded a prerecorded backtrack with a metronome. So I didnt record to Cubase click.

Back at my home studio. I want to add some plugins which are based on automation and so on. The song is set in 150 bpm. The default setting in Cubase is 120 so I change the tempo track to 150 bpm. Now the strange magic happens: The audio files have moved! They have been stretched out… What is happening?

I added three pictures for you guys to look at, the first image is 120 bpm, everything sounds as it should. Second picture, I have raised the tempo. As you can see, the files are stretched out. Third, I have lowered the tempo and the files shrinks.


Does anyone have an idea how to solve this? I use Cubase Artist 7.


Thanks in advance!
