I imported a 16 measure audio file and when I play the song, the audio file stops playing at the end of measure 12. I'm missing 4 measures of the audio file while BIAB continues playing the other tracks in the song. I'm just using this 16 measure song to test the process, so I'm not sure what's going wrong. Any ideas?
