# Companion

If you plan to use MixEffect with a Stream Deck, you'll want to download the free [Companion application from Bitfocus.io](https://bitfocus.io/companion/).

Next, configure the Companion app to communicate with MixEffect. There are currently two ways to control MixEffect from Companion:

* [Generic OSC Module](/automate/osc/companion/generic-osc-module.md)
* [Native MixEffect Companion Module](/automate/osc/companion/native-module.md)
