FM Broadcaster
FM Broadcaster is a companion app of Ferromagnetic on macOS, which captures the output texture of the visualizer and forwards it to Syphon or allows saving into a file.
It is distributed as a standalone binary for compatibility with data streaming protocols that are not available on the App Store due to the sandboxing of applications. (See relevant issue on Syphon-Framework#10)
FM Broadcaster is an optional free extension for FM Producer users. Download it below:
Note: It requires Ferromagnetic version 2.5 and above, with FM Broadcaster option enabled in the settings menu.
