Recent Changes New feature allows user to control how many channels of sound are being used for sing-a-long. Default is 3 - one loud vocal, one soft vocal, and one music only. 2 is loud vocal and music only. 1 is loud vocal only. This parameter is set in the LASERKID.INI file as Channels=3 Lowering this setting will decrease the time loading the music files, and will cause the music to be ready to play sooner.
