GoSing Karaoke Player

oSing is a complete karaoke system that is compatible with the file formats KAR, MID and MK1. The program lets you play your karaoke songs on a fully configurable and full-screen display. It will display, of course, the lyrics but also a kind of traffic light to tell you when you should and should not enter. It supports compressed ZIP files and you can change a whole range of parameters, including tempo, in real time whilst playing your songs. The program is completely free, requires no installation, and you can find some great designs for playback on your webpage https://www.gosing.com/.
