Hi I had the same problem Fix - ( Before you do a Mixdown ) go to : Preferences > Sound Device Change from Wavert or Asio to Wave ( Remember to click ok ) Do the Mixdown and after it has finished remember to change back to Asio or Wavert for your next recording. Why it works like that I don't know.

Hi

Just something that puzzles me a lot.

Are there anyone with an Apollo Audio Interface that feels there voice sounds better when they press the invert phase button on the Apollo ?

Very Nice Keep going
