Fixed Vocoder Issue
If you have been having issues with your vocoder or any other issues with devices in your rack the big problem may be that
YOU STILL HAVE AN INSTANCE OF RECORD INSTALLED WITH THE NEW REASON PLATFORM!
If you have a mac google this app called appcleaner it should come right up. Install it on your mac in the applications. Click the applications icon at the top of the app interface and look for Record. Check the box and delete it completely from your system. Once you do this your vocoder should work.
I have been messing with this for about two weeks now until I found this app. Its free and it fix your vocoder problem. Enjoy
