Cannot see what the problem should be here.
Try importing it as a .wav file.
Try and make your source file a wave file or convert it to wave outside of cubase and then import.
The way you are currently doing it means Cubase SX is converting the MP3 and importing - if there is something going wrong in the conversion as least this way it is cutting that stage out.
If SX fucks up the basic importing of a wave file then we are deep in it. |
