The customer originally used the DYB2001_CBS for this project. It has since been changed to the DYB2003_CBS because of the larger memory capacity. The horse ride was purchased and the DYB2003 was added to play various sound files. It has been used at several children’s birthday parties. When the ride starts it will play the first sound file. When that file is finished the child can pull on the reigns of the horse and a new sound file will play.
