MixEffect can connect to most ATEM Switchers running version 8.5.x of the ATEM software.

When connected, you have nearly total control over the switcher. It’s like having the complete ATEM Software Control app on your iPhone or iPad, with features and usability enhancements that can only come from being on a mobile-first environment.

Add a Switcher

You can add a new switcher to MixEffect by following these steps.

  1. Go to the MixEffect Home.
  2. Tap the + button.
  3. Tap New ATEM Switcher.
  4. Enter a name for your simulated switcher (e.g. ATEM Mini Pro).
  5. Enter the IP Address for the switcher (e.g. This is the same address you use in the ATEM Software Control application on macOS and Windows.
  6. Tap Add.

Add a switcher

You can add multiple switchers in MixEffect, even to the same switcher. Create sets of switchers that have different settings depending on the project you are working on.

Discovering ATEMs on the Network

Newer version of MixEffect automatically try to discover ATEM switchers on your network. In the New ATEM Switcher sheet, a list of switchers found on the network will appear. Tap on one to populate the name and IP address fields.

NOTE: Some ATEM switchers may appear in the list but are unable to connect due to the fact that MixEffect and the switcher are on different networks. Refer to the Connection Help section for troubleshooting tips on how to connect your ATEM switcher to MixEffect.

Default Section

Tapping on the switcher image from the detail page will take you to the default section defined for the switcher.

You can change this section by editing the switcher and closing a new default section in the drop-down list.

NOTE: The section list may contain sections that stewed not supported by your switcher. Make sure your switcher supports the feature backed by your choice or you may see a blank screen.


You can control MixEffect from Companion or any app that supports sending of Open Sound Control (OSC) messages. Refer to the documentation in the OSC section for more details.

SuperSource Macros

If you have an ATEM switcher that supports SuperSource, you can instruct the switcher to run a macro when entering or existing a MixEffect SuperSource preset. This powerful feature allows you to configure exactly how your switcher should be configured when transitioning between presets. Learn more about this feature in the SuperSource section.

  1. From the MixEffect Home, tap the gray connect symbol to the left of the switcher name for the switcher you wish to connect to.
  2. Or, tap on the switcher’s name to bring up its Detail Screen. Then, tap Connect.

How a button operates is indicated by the following visual affordances:


A section related to a particular feature on your ATEM switcher. For instance: the Program bus, Next Transition, or Downstream Keyer.


If you have used Blackmagic’s ATEM Software Control on macOS or Windows, some of these panels will look familiar.

Pages are collections of panels arranged in a particular layout.

MixEffect comes with three different layouts for organizing your panels and buttons:


Mix Effects Bus

If your ATEM switcher supports multiple mix effects buses, a segmented picker will appear at the top of the screen allowing you to select the current M/E bus you wish to control. Buttons and panels that are tied to the currently selected M/E will update when you switch buses.
