I'm running a new MacBook Air, newest version OS 10.15, I have a Studio 68c version 4 with the most recent drivers. I'm plugging my condenser mic into input 1 on the 68c, 48v is on, I can hear the mic through the monitoring in my headphones. I create a track in the software, set the input to input 1 (or L as its labelled in the I/O), I arm the track....nothing. I'm doing everything right, but I'm unable to get sound into the software. Any one! Please help!!!
