Quartet: General

Can ONE, Duet or Quartet be powered from the iPad/iPhone dock connector?

No, the iPad and iPhone cannot supply nearly enough power through their dock connector to allow Apogee interfaces to function properly. ONE can be powered by two AA batteries for remote operation, but the Duet and Quartet require their power supplies to be plugged in at all times.

Can ONE, Duet or Quartet route audio from an iPad directly into a Mac?

Apogee interfaces are only able to communicate with one computer or iOS device at a time. It is possible to route the audio from an Apogee interface connected to an iOS device into an Apogee interface connected to a Mac. The USB-A Port on the back of Duet-iOS and Quartet-iOS is only for MIDI data, and cannot be used to pass audio.

How do I know what version of Maestro is installed on my Mac?

To find out what version of Maestro you have installed:
  • Open Maestro 2 (found in your Mac’s application folder) and click on the “Apogee Maestro 2″ menu in the upper left-hand corner of the desktop menu bar
  • select “About Maestro 2″. This will bring up a window showing you which version you have installed (see example below)

How do I connect Quartet to my iPad, iPhone, or iPod Touch?

Is Quartet USB Core Audio Class Compliant?

Yes, the Quartet USB audio connection can be plugged directly to the USB port of any Mac with OSX 10.6.8 or higher, without installing any additional drivers or software, and fully function as an Audio I/O device. All of the Front Panel controls (Mute, Dim, Sum to mono, Input/Output levels) are fully functional without installing any software.

You will need to install the latest Quartet installer package from Apogee’s site for full access to functions such as toggling input source (ex. from Microphone to Instrument), enable speaker sets, low latency monitoring, etc.  These functions and many more are accessible through Apogee’s Maestro 2 Application (Automatically included with the Quartet Software Installer)

Can I use two Quartet’s simultaneously?

Yes, you can connect two Quartet’s to your Mac and use the inputs and outputs of both units at the same time.  This is done through a process called aggregation.

 

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

 

See “Using 2 Quartet’s – Aggregate Device Setup” for more info.

Using 2 Quartet’s – Aggregate Device Setup

Before you get started, make sure that you have updated the firmware on both Quartets to the most recent version. After the firmware has been updated, run the most recent Quartet software installer.

 

Setup

1) After you have ran the software installer, open up “Audio MIDI Setup”, found in Applications > Utilities.

2) Make sure both Quartets are set to the same sample-rate by selecting each device and choosing the correct sample-rate from the drop-down menu.

3) 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”.

4) In the right side of Audio MIDI Setup, select the checkbox beside each Quartet. The Clock Source drop-down menu should blank.

5) 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. The Aggregate Device should now show the speaker and mic icons next to it.

 

 

Using Logic

1) Launch Logic and go to the Audio Preferences (Logic Pro > Preferences > Audio). Click on the drop-down menu for the Output Device and select “Aggregate Device”. It should automatically select Aggregate Device for your Input Device as well. Click the “Apply Changes” button at the bottom of the window.

2) To set up the I/O labels in Logic for your Aggregate Device, go to the Options menu, select “Audio” and then “I/O Labels”. The I/O Labels window will appear. Click anywhere in the window and then press Command-A to select all. Now click on one of the circles in the “Provided by Driver” column. This will select all of the i/o labels for your Aggregate Device. Close the I/O Labels window.

3) Now you’re ready to record with your Aggregate Device! Create a track and assign your input and output.

 

Hotplugging devices or sleep/wake while Logic is open isn’t recommended while using an Aggregate Device. If you hotplug or sleep/wake, you may have to quit and relaunch Logic.

 

Using ProTools

1) Launch ProTools and before creating or opening a session, select “Playback Engine” by clicking on the Setup menu. Select “Aggregate Device” in the top drop-down menu for the Playback Engine and then click “OK”. ProTools may have to quit and relaunch after this. 

2) After you’ve relaunched ProTools, go to the “I/O Setup” by clicking on the Setup menu and selecting “I/O”. After the I/O Setup window opens, click “Default” in both the input and output tabs.

3) You can customize the i/o labels by double-clicking on an entry and entering a label of your choice.

Hotplugging devices or sleep/wake while ProTools is open isn’t recommended while using an Aggregate Device. If you hotplug or sleep/wake, you may have to quit and relaunch ProTools.

 

 

Troubleshooting

If you ever run into “choppy” audio or clicks and pops while using an Aggregate Device, here is a list of troubleshooting tips:

– Make sure both devices are set to the same sample-rate in Audio MIDI Setup

– Quit and relaunch Logic or ProTools.

– Reload the driver in Logic by going to the Audio Preferences, toggling the I/O Buffer Size back & forth and then clicking “Apply Changes”.

– Try raising the I/O Buffer Size in Logic’s Audio Preferences or ProTools’ Playback Engine.

– Open Audio MIDI Setup, delete Aggregate Device and create a new Aggregate Device using the steps above.
