Aggregate Device For Mac

Sep 12, 2019 When you’re done, right-click the aggregate device in the column on the left, and select the ‘Use This Device For Sound Output’ option. Play audio, or video with audio, on your Mac and the audio will be routed to all the devices you selected to create the aggregate device. If you want to use multiple audio input devices at once e.g. Open the Audio MIDI Setup application on your Mac and go to the Audio Devices window. Click on the plus icon at the bottom left of the window to create a new Aggregate Device, then double click in its name field and assign it a name. Jul 20, 2020 Mac audio device drivers. All of your connected audio devices will show up in the Audio Devices window. That includes built-in microphones and speakers, audio interfaces, HDMI connections, and aggregate devices.

If you have a number of audio interfaces on your Mac then you might find yourself either switching between them for Pro Tools sessions, or even wondering if you can use the power of all of them at the same time.

Using the Aggregate Device option in the Audio MIDI setup window on your Mac you can create flexible input and output setups for any audio application on your Mac.


Create An Aggregate Device In Audio MIDI Setup

  1. Using Aggregate Devices and multiple audio interfaces. Live Versions: All; Operating System: All; Aggregate devices on Mac. On Mac, it is possible to choose different interfaces as Input and Output device in Live. It's also possible to combine multiple audio interfaces into an aggregate device at a system level.
  2. To create an Aggregate Device, you’ll need the modules or instruments that you want to use (for example a TR-8, a Boutique such as a JP-08, a Super UA and a TB-3), a USB port to connect them all, a Mac computer and your monitoring setup (headphones, speakers).

To create a new Aggregate Device on the Mac simply open the Audio MIDI Setup application and then use the drop down menu in the bottom left of the window. Choose ‘Create Aggregate Device.’

You will then be presented with a list of all available audio interfaces. Simply tick the ones you want to use, in this example we are using an Apollo Twin connected to a 4-71-D via ADAT and a PreSonus StudioLive 16.0.2.


One thing you need to make sure is that of is that one interface is the master clock source and that all other audio interfaces in the aggregated set-up are running at the same clock speed. Once create our set-up looks like the image shown below.

As you can see we now have a possible 36 inputs and 28 outputs available to us. Remember when using Pro Tools a maximum of 32 inputs is available, this will not be the case on other DAWs.

Setting Up The I/O In Pro Tools

To make sure Pro Tools can ‘see’ all the available I/O you need to go to the ‘Setup’ menu and select ‘I/O’ You’ll see the image shown below.

The fastest way to get all the I/O set-up is to delete all the inputs then click default and repeat this process in both output and bus tabs too. You should now have all the I/O available to you.

Selecting The Inputs And Output In Pro Tools

Now when you create new tracks in Pro Tools you will have all the inputs and outputs available for use. See below.

This is a cool way of handling multiple interfaces without going through the pain of relaunching Pro Tools or for getting lots of I/O from a number of interfaces. One such scenario may be wanting to track a guitar via the Apollo with effects but using an Apogee Ensemble as you main interface. Or tracking guitars via Eleven Rack and whilst using an Apollo as you main interface.

In some cases the Mac will let you mix the protocol, so in this scenario we’ve got a Thunderbolt and a FireWire interface running as an aggregate device. Unfortunately you can’t do this with Pro Tools HD interfaces.

You can create Aggregate Device to increase the number audio inputs and outputs available at the same time. You can also use an Aggregate Device if your application doesn't support separate input and output devices.

Pro Tools Aggregate Windows 10

With Logic Pro, GarageBand, and MainStage, you can use a separate device for input and output. For example, you can use a USB microphone for input and the headphone jack of your Mac for output. Some applications not manufactured by Apple don't support separate input and output devices.


Set up an Aggregate Device

When you create an Aggregate Device, make sure to connect all external audio interfaces first.

  1. From the Finder, choose Go > Utilities. Open the Audio MIDI Setup application.
  2. Click the Add (+) button on the bottom-left corner in the Audio Devices window and chose Create Aggregate Device.
  3. A new Aggregate Device appears in the list on the left side of the window. To rename the device, double-click it.
  4. With the new Aggregate Device selected, enable the checkbox labeled 'Use' on the left side of the Audio Devices window. Do this for each device you want to include in the Aggregate Device. The order in which you check the boxes determines the order of the inputs and outputs in applications like Logic Pro and MainStage. For example, the first box you checked will be inputs one and two, the second box checked will be three and four, and so on.

    The list on the right shows the currently connected audio devices and the number of input and output channels for each one.

  5. To use the clock of a device as the master clock for all the combined devices, choose the device from the Clock Source menu of the Aggregate Device. Choose the device with the most reliable clock.
  6. If your audio devices all work with word clock, connect them together using a word clock cable. Connect the cable from the device you designated as Clock Source to the input of each other device. Refer to your audio device product documentation for specific details.
  7. If any of your devices don't work with word clock, select the Drift Correction checkbox for any devices not designated clock master.

Use an Aggregate Device with Apple music creation software

  1. Open your application.
  2. Do the following depending on the application you're using:
    • For Logic Pro, choose Logic Pro X > Preferences > Audio, then select Devices.
    • For GarageBand, choose GarageBand > Preferences > Audio.
    • For MainStage, choose MainStage > Preferences > Audio.
  3. Choose the Aggregate Device from the Output Device pop-up menu. Logic Pro and GarageBand automatically set the Input Device to the match the selected output device, which you can change if you want to use a different input device. In MainStage, you must manually select the input device.
  4. In Logic Pro and MainStage, click Apply Changes.
    GarageBand automatically switches to the new input device.

Use the Aggregate Device as the sound output of your Mac

Aggregate Device For Mac Operating System

When you set the Aggregate Device as the sound output for your Mac, sounds from other apps on your Mac play through the Aggregate Device. The Aggregate Device also becomes the System Setting option in the Output and Input Device menus of your Apple music creation apps.

  1. From the Finder, choose Go > Utilities. Open Audio MIDI Setup.
  2. Control-click the Aggregate Device in the left column, then choose 'Use this device for sound output' or 'Use this device for sound input.'
