Yet another beta version up and ready to test.
1.5e has a number of bug fixes (most important is that program changes are now done at the right file position), some meta track command enhancements and a new lyric karaoke mode.
Please bang on it. Make it break. Pull your hair out when it doesn't work ... and let me know if you get stuck or have suggestions.
Oh, and have fun making music!
