I'm having a very disappointing problem. I've just created two new pieces of music and then I released that I couldn't export them fully. They stop exporting as soon as it hits a different song-gobble automation (tempo and time sig.). Please help me! I've tried using the default settings. And I also have the 1.1.3 stable version. So...
The issue is known and it should have been fixed already. Please try the latest beta of lmms-1.2
