Mixing multiple tracks via Faderport 8 in Studio One 6.1.1. In Latch mode... mixing going fine, until suddenly the faders move, the automation track on the screen goes up and down, but the volume of the track doesn't change. At first I thought it was just the piano track... but it everything. I have volume automation on most tracks, but none of the output levels change. I've rebooted the computer and restarted everything twice... no effect. Something is disconnected. Please respond....
