Duet 2 (USB) Maestro Error “No Apogee Systems Found”

Symptom: Apogee Maestro will not properly recognize Duet 2 (USB) if Mac user is logged into a Guest Account.  Maestro simply says “No Apogee Systems Found”.


Resolution: Confirm you have latest Duet software installed (you can download here), go to Apple Menu>System Preferences>Show All>System Accounts>My Account view>Set User Name to Admin, restart the Mac and Maestro will now launch successfully.

How do I use the custom I/O labels in Logic?

For Logic 9 and lower:

With your Apogee devive selected as the input/output in Logic’s Audio Preferences, go to the “Options” menu and select “Audio” and then “I/O Labels”. Now you can select the custom Apogee labels for your device.

For Logic X and higher:

  • Go to Logic’s Mix menu at the top of the screen and select “I/O Labels…”
  • There are several columns: Channel, Provided by Driver, User, Long, & Short.
  • To use the labels provided by the Ensemble:
    • Click the button in the Provided by Driver column.
  • To enter your own custom label:
    • Click the button in the User column.
    • Double click the “-” in the Long column, type in a new name, then press Return on your Apple keyboard

When recording, the input is delayed in my headphones

Decrease the I/O buffer size in your audio application. See “How do I set my software’s I/O buffer?” for more information.


I’m not getting any output from audio software applications. What should I check?

1) Verify the unit is properly connected and recognized by the Mac.  You should see 4 icons on Duet’s OLED (input 1, input 2, speaker out, headphone out).

2) Select Duet USB as your Mac Sound Output device in System Preferences/Sound or in Audio MIDI Setup (Applications/Utilities).

3) If you have chosen Mixer for the output selection in Maestro, then the Software Return fader must be raised to send audio software application outputs to Duet’s outputs.
