I recently upgraded to Mojave on my Mac. Prior to the update, I had no issues re-amping through my Axe Fx II from my Studio 1824. Since the update, there seems to be feedback loop that renders the re-amped audio completely unusable. My setup for the re-amp is as follows: The D/I track is routed to a line output on the back of the Studio 1824, which goes through a passive re-amp box and is plugged in to the front of the Axe Fx. The unbalanced outs from the Axe Fx are connected to the inputs on the front of the Studio 1824. This set up used to work and allowed me to monitor the wet re-amp signal as it was recording (also was super handy for dialing in the tone). Ever since the update to Mojave, it hasn't worked (this could very well be a coincidence). When I try to record the re-amp signal, there is a horrible screeching feedback loop regardless of output volume on the re-amp box and the output of the Axe Fx.
What can I do to fix this? Is there a better way to re-amp other than the setup I described?
