This is a 14th century traditional English carol. (If you really like the tune, please check out the heavenly voices of the Anonymous 4 on their album, "On Yoolis Night", for an incredible vocal arrangement.) This is a remix of a sequence I did in 1995 with my old soundcard.
This sequence uses the default pitch bend range. But if you don't play the file all the way through, then hit that old reset button anyhow ... just to clear other possible parameters which may affect how the next file is played.
