If you are having a problem in Fruity Loops or any other DAW with your Audio Interface, but it works nicely in other programs then this can help you.

- Open “Audio MIDI Setup” from Applications -> Utilities -> Audio MIDI Setup
- Click “+” and select “Create Aggregate Device”
- Choose your Audio Interface with a checkbox
- Close Audio MIDI Setup and select this new device in DAW.


Voilà!
I was trying to give up FL because I couldn’t solve this problem. Thanks to you. Thank you very much. Thank you from the bottom of my heart
