The Revelator IO 24 offers a number of robust routing solutions that can be easily utilized to incorporate Studio One as part of your live streams. Whether you wish to live stream a mixing session or you are performing and wish to use Studio One to play backing tracks, Studio One can be seamlessly incorporated into your live streams using the Revelator IO 24's virtual audio streams and OBS Studio. The same steps will also apply to whatever your chosen DAW is. 


On Windows, the Revelator IO 24 acts as a 6 In/6 Out audio interface. The first two channels are the main In/Out on the interface while streams 3/4 and 5/6 are the virtual streams. To route general system audio (iTunes, Spotify, YouTube) click on the speaker icon in the bottom right of the screen and select Playback L/R (Revelator IO 24) as your audio device. 




This will route all system audio to the playback stream which can be controlled using the playback fader in Universal Control. 




Next, open Studio One. On the Start page, click Configure Audio Device. A new window will open. Click the drop down menu and select Revelator.




Once you have selected this, click ok. Your revelator will now appear as your audio device on the Start page. 




Once your device has been setup, open the song you wish to use as part of your live stream. You may need to configure your Audio I/O within Studio One. To do this, navigate to the menu bar at the top left of the screen and click Song -> Song Setup -> Audio I/O 




Click on Outputs and then click Add Stereo to add a stereo output for the three Output Streams (Playback, Virtual Output A, Virtual Output B). Click Apply, then click Ok.




Next, go to your master channel and Select Virtual Output A as your output in Studio One.




This will send all audio from Studio One to the Virtual Output A. This can be controlled using the Virtual A fader in Universal Control. 




With this setup, you can now control your general system audio on your playback fader and your audio from Studio One on the Virtual A Fader in Universal Control. To select Mix A as your output stream, first click on Stream Mix to activate it and then click on Mix A and turn up one or both of the faders to set the level for your system playback and Studio One audio. 




The next step is to set up the device in OBS Studios. First, open OBS and create a new scene by clicking the Plus button in the bottom left corner. You can name this scene and save it for future use. 





Next, move to sources to add the Studio One window for your livestream.  To do this click the Plus button to add a source and then select Window Capture. Click create new and name your display. 




Select Studio One from the from the displays in the Window drop down menu. 




Next we will move to the Audio Mixer to route our Audio to OBS. By default, there will be two audio tracks available when you create a new scene in OBS. These are Desktop Audio and Mic/Aux. For this example, we will be using Stream Mix A to send all of our audio to OBS as a single stereo stream. 


To do this, click the settings cog under the meter on the Mic/Aux Channel and select Properties.




In the next Window, click the Drop down menu and select Stream Mix A as the Input device.



All that is being sent to Stream Mix A Audio in Universal Control is now being sent to OBS. You can control the levels of each audio stream, including your microphone, using the faders in Universal Control.  


For additional control during your livestream, you can download and install the UC surface app for iPad. This will allow you to have the mixer open in front of you on a separate device during your stream.


You are now ready to livestream audio and video on your streaming platform of choosing.
