I am getting midi feedback loop when assigning an IAC port to both the input and output of the Mackie Control Device Panel in the Devices Set Up Menu in Cubase 9.0.1. When I assign other midi input/outputs to the same Mackie Control Device Panel I do note get a feedback loop. The feedback look only happens when I use the IAC bus. Nothing else is assigned to the IAC bus.
Any ideas or suggestions? Thanks in advance.
