Using a Virtual Driver in CASTER #
If you want to use GroundControl CASTER to monitor the audio stream of this virtual driver, add an input track for the virtual audio device you created. This is shown as “Ableton To Protools” in our example.
Note that when monitoring through Caster, the stereo channels 1&2 usually corresponds to the master output of the DAW you are using.
