atemOSC

The application acts as a bridge that translates OSC, MIDI, and HTTP messages into commands for Blackmagic Design ATEM video switchers and HyperDeck devices. It discovers compatible hardware on the network automatically and offers in‑app documentation for the supported command set, allowing users to control switcher inputs, mix‑effect blocks, transition parameters, and related functions without manual configuration.

It is aimed at live‑production engineers, streaming technicians, and anyone who needs to integrate ATEM switchers or HyperDecks into custom control surfaces, such as MIDI keyboards or software controllers. By supporting multiple protocols, the tool lets users replace separate utilities like OSCulator with a single, unified interface.

The software has evolved since its 2012 release, adding features such as multi‑switcher handling, HyperDeck control, Web Presenter support, and cross‑platform availability on macOS, Windows, and Linux. The current version maintains full compatibility with earlier OSC commands while simplifying setup and extending functionality beyond the original ATEM‑only focus.
