Sync lights with music similar to hue sync or hue disco?

Has anyone developed a side app similar to hue sync or hue disco app to sync the lights in smartthings with music?
Is it even possible to develop such an app or capability with WebCore or rules API?

Doubtful. Zigbee ans ZWave network transports are not designed for the high speed control signals that would be required for music sync. As it is, you really canā€™t even get sub 5 second resolution on timingsā€¦ (just do a search on the number of times people have asked how to make a bulb flash on response to an alarm) Music or video sync would be completely untenableā€¦
