  • To open, edit or close a layout, click on the editing pencil to switch to edit mode.
    You can now move tiles with a long press, or tap on them to change their size, color and, in the case of user buttons, their function.

    If you would like to add new functions to your layout, click on the tile icon to open a toolbar with additional tiles. Simply drag and drop a tile into your layout.

    If you tap on the layout itself and then on the yellow burger (menu) icon, you can save your layout. Layouts are saved to the files section of your device and can be shared with others. You can also load one of the many default layouts that are included with the CCA. 

  • There are two possible reasons for this.
    1.    The tile is locked, recognizable by the padlock icon in the tile. To unlock it, press and hold.
    2.    The function of the tile is not included in your subscription, recognizable by the not available sign in the tile. To use it, decide in favor of a subscription or try out a trial version.

  • MIDI (Musical Instrument Digital Interface) is a signal protocol that makes it possible to connect electronic musical instruments with each other and with computers. There are many different controllers that can be used as physical control elements in the Companion App.

  • In the CCA, go to the MIDI menu and enable MIDI.

    Now select a function from a function area, such as Lock from Global Actions. Click on the row that appears: the row will turn blue to indicate that the CCA is waiting for a MIDI trigger.  Press the button on your MIDI device to which you want to assign the function. The CCA will register the MIDI button press (or knob turn) and allocate it to the function selected.

    The MIDI menu can be used to check assigned functions: a yellow border will be highlighted on any function assigned to a MIDI controller when pressed.

    Using this method it is also possible to assign the same function on several cameras (for example Exposure Index on camera A and camera B) to the same physical button.

  • Tap on the editing pencil which will open the edit mode. In the edit mode you will find the option to add, remove or rename tabs. Tabs are supported in the Premium version on iPad and Mac.

Known Issues

  • Playback cannot be started if the recording codec of the last recorded clip does not correspond to the currently selected recording codec.
  • If the app is used to adjust lens motors, unreachable values (outside the value range of the lens) can cause the Warning: Unable so set value to appear. As several CAP commands are sent when using the app in this way, the warning may appear several times.
  • The default layouts for the iPad and Mac are developed for landscape use. An automatic change of layout when turning the device is not provided for iPad and Mac.
  • In the frame grab tile, the correct frame lines cannot always be applied to the frame grab.
  • Frame grabs are currently not supported on ALEXA 265.
  • There is currently no indication to the user that it is not possible to calibrate the lens motors during recording.
  • Occasionally, after intensive use of the layout editing mode, it may not be possible to place a tile. In this case, save the layout and restart the app.
