I’ve run into a strange issue within 8.5. I created a track with no issues, went back to make some finishing touches and one audio channel and a group buss are not working. All other channels are working. Have checked routing. The only thing is that I have recently installed new plug ins. The instruments that are routed to the group buss work if I route them directly to the master buss but the audio track does not have any signal no matter what I do.
I am on a late 2013 15" MacBook Pro, 2.3ghz, 16 gb RAM
