mix down problem

Hi all…anyone have thoughts on this?..When I mix down a project to a stereo wave file I’m finding that on playback of the file that it is playing back 1 to 2 semitones lower than the project file!!! … Am using CB elements 7, laptop pc dual core, windows 10…thanks in advance for any replies

Sounds like a sample rate problem. You computer might be at 44.1Khz while the file mixed down is 48kHz. All I can think is happening!

I’m having the same issue. How did it go?
