Playlist-based remote control application for OnTheAir Node

OnTheAir Live is a playlist manager for Live productions that comes bundled with OnTheAir Node and provides the user interface for adding media and controlling playback. As its name implies, OnTheAir Live has all the features required for Live operations such as Cue mode and A/B roll.

Control Multiple OnTheAir Node

Control multiple Nodes from one OnTheAir Live. As it's a client-server type of application, you can run OnTheAir Live on a different computer than OnTheAir Node, so you can have OnTheAir Live running on a computer in the control room, while the OnTheAir Nodes are running on a computer in the machine room.

About these specifications

We know that some of our users can not upgrade their macOS very often. This is why Softron tries to maintain compatibility with older versions of macOS as much as possible, but it is not always possible to achieve. Because Operating Systems are usually significantly improved over previous versions, Softron must use many of the more capable built-in functionalities inherent in Apple's latest OS releases. Failing to do so would mean that Softron software would essentially be blocked from using the new Frameworks provided in the OS. For this reason, Softron's free support is provided only on the current and previous macOS versions. Also, most of our tests will be done on these macOS versions, and only basic tests will be done on the previous OS. We will always try to help, but in some cases, the best solution is to upgrade your macOS to a more recent version.

Softron does not warrant that these recommended configurations will always meet specific user requirements. They are intended as guidelines and are based on extensive testing that Softron has done, they can be changed without notice. Hardware, drivers, software and operating systems change regularly and we advise users and prospective users to evaluate their requirements in their specific environment/workflow using Softron demo licenses that are available for downloading from Softron's web site.
