OnCue is the name given to wireless sharing in OnSong. This is different than OnSong Connect, in that it uses Apple's wireless sharing frameworks to allow for sharing over Bluetooth. This provides the ability to beam and stream content to devices running OnSong without the use of WiFi.
Since OnCue is built on top of Apple's frameworks for wireless, peer-to-peer connectivity, there are a few things to consider as well as some limitations.
Beaming is the process of sharing the currently viewed song or set with nearby users. Once received, those users will need to navigate and scroll through the song on their own.
Streaming allows the user who sets up the streaming session to control the connected devices. This will send song content and navigation signals to the connected devices.
