Att:VideoTrack:

Thanks for guidance. Here are the answers for your question:

The stuttering happens to every song that uses RealTrack,
only one instrument,
The beginning of the end of the song is a 2-bar after the song finishes,
The stuttering is in short duration at the beginning of the first bar of the 2-bar ending,
Sorry I don't know how to create an audio file of the song to attach here,
I use ASIO driver...
Thanks a million..from California
