MIDI aggregate device output problems

an "aggregate device" is normally used to combine input sources. for your purpose, you need to make a "multi-output device" (in MIDI settings) to hear the audio from both devices at the same time.

well, I'm stumped. yes, everything looks correct. the only other thing I can think of, would be to Start up your Mac in safe mode. you won't be able to test your sound settings, as sound is disabled while in safe mode. but you can boot into safe mode and run the Mac for a few minutes, and then restart normally again. sometimes a safe boot followed by a regular boot resolves issues.

if no resolution, please let us know. someone else may have an idea.

have you made sure that all your desired devices are selected in your "multi-out device" settings?

and then, before starting a recording, are you using your menubar sound selection to choose "multi-out device"?

Any luck fixing this issue?

Thanks for this advice !! I had the same problem and this solved it.

I had used the aggregate device for output before and it worked, but I switched laptops and now it doesn't.
