Hi Gordon,
Thank you so much for your response. I have tried it using Mackie protocol on windows and it did not work. I have done it exactly the same way you advised but it is not working. I used another DAW (Reaper) and it worked flawlessly. I also checked through the Allen and Heath link (https://www.allen-heath.com/media/DAW-Control-Setup-Notes-V1.40.pdf) and they don’t have set up notes for Adobe Audition CC.
Thank you so much for your time.
Franklin
