If Quad Cortex is selected as the main audio device on your computer, you will hear the computer audio through Quad Cortex Outputs 1/2 and Headphones Output. This feature lets you jam along with Youtube™, Spotify®, iTunes®, or your DAW tracks with low latency monitoring.

TRS Outputs 3/4 can also be used for hardware monitoring on macOS:

  • Open the Audio MIDI Setup app.
  • Click on Quad Cortex.
  • Click on Configure Speakers.
  • Change the speaker channels "To Out 1" and "To Out 2" to "3" and "4" accordingly. 
  • Click on "Apply" to save the settings. 

Recording Quad Cortex's processed signal, dry input, or specific rows is also possible. In either case, you will hear your signal from Quad Cortex before it's routed through the DAW, which is great for low latency monitoring.

Multiple inputs and outputs can be used by tapping the Input and Output blocks on both sides of The Grid. USB Inputs and USB Outputs are also available here. This feature allows getting different routings without connecting any additional cables to the unit. 

Monitoring with both Quad Cortex and a DAW at the same time could cause phase problems. In order to avoid any issues, turn off the input monitoring in your DAW.
