Apogee Quartet & Duet – Connecting and using both on the same Mac

In this tutorial we will show you how to connect and use a Quartet and a Duet at the same time.

First make sure your Quartet and Duet firmware and software are up to date.

Both devices must be directly connected to an available USB port on the Mac.  You cannot daisy chain the second device from the first devices’s USB MIDI port.

Open up “Audio MIDI Setup”, found in Applications… Utilities.

Make sure the Quartet and Duet are set to the same sample rate by selecting each device and choosing the correct sample-rate from the drop-down menu.

Create an Aggregate Device in Audio MIDI Setup by clicking on the “+” icon at the bottom left side of the device column and selecting “Create Aggregate Device”.

On the right side of Audio MIDI Setup, select the checkbox next to Duet and then Quartet.

The device you choose first will be the first inputs and outputs to show up in the recording software.

If you want the six analog inputs to show up first…. Duet’s two and Quartet’s four…
you will want to select Duet first.

If you choose choose Quartet first… Duet’s inputs show up as inputs 13 and 14 as they will come after Quartet’s four analog inputs and eight digital inputs.

With “Aggregate Device” still selected, go back to the bottom of the device column and click on the “gear” icon. Choose “Use This Device For Sound Input” and “Use This Device For Sound Output” to set your Aggregate Device as the default input & output for your Mac.

You can also re-name the Aggregate Device to anything you like

Now in your recording software simply select the new Aggregate device.

Logic allows you to make custom labels for the inputs and outputs and can come in handy when dealing with this amount of I/O

Go to Options, select “Audio”, and then “I/O Labels”
Click anywhere in the window and then press Command-A to select all. Click on user and now create custom labels.
Remember you have to do this for Mono and stereo channels

Now just assign your inputs and outputs in your recording app and you are ready to record.
