Hello, I have a song that is 4:08 in length. When I mix it down using export>audio mix down to MP3, cubase adds a 30 second chunk of the song AFTER the 4:08 end point. Yes my markers are set to cover the song from start to finish. Has never happened before. Help
So you actually hear the song finishes and then there is some other part of it comes in?
What about the same mixdown to wav?
Perhaps the arranger track is enabled?
Yes, it totally ends, then like a few seconds later a section from elsewhere in the song abruptly starts 
Just tested with a WAV file and it came out fine! It seems to be related to MP3. Any ideas?
Ha…just did a search and came up with just one other thread with exactly the same issue three years ago…and that was you too.
What os are you on?
LOL. I knew I had experienced this before. No idea how I resolved it. Ugh. OSX 10.12.3. No issue on previous songs in last week though. Nothing has changed…
