When using Apogee interface with Cubase, output volume level goes to max.

Symptom: When opening any Cubase session or selecting Apogee as the audio device, the output goes to full volume every time.

Solution: In Cubase, go to Devices > Device Setup > Control Panel > Core Audio Device Settings. Under Options, verify that set device attenuation to 0 dB is unchecked.

Can I use two interfaces at the same time for more I/O? (aggregation)

Yes, Mac OS allows you to use multiple audio devices at once and use them as-if they were a single device. Through a process called Aggregation, inputs and outputs of the separate devices are combined and can be used simultaneously.  For example, you can aggregate 2 ONE’s, effectively creating a device with 4 output channels.

Apogee supports device aggregation for a maximum of 2 devices only on Mac OSX 10.7 (Lion) or greater.


Apogee devices that support Aggregation:

  • Duet 2
  • Quartet
  • GiO
  • JAM
  • MiC
  • ONE


To create an aggregate device and use multiple interfaces simultaneously:

  • Open Audio Midi Setup (Located in Applications/Utilities/ on your Mac)
  • Click the + from the button left of the window
  • Select “Create Aggregate device”
  • Double-click the newly created device’s name “Aggregate Device” and rename it if desired
  • In the right side of the window, select the devices you wish to aggregate. For example ONE, Built-in Input, Built-in Output.
  • For best results, be sure Apogee device is selected as the Master Clock
  • In your recording application, select the device name you’ve just created.
  • To select this device to be your default for Mac sound, Right click (or control click) the device in Audio MIDI Setup and select “Use this device for sound input/output”
  • Select the Output speaker channels by clicking “Configure Speakers”, selecting the stereo tab and assigning destinations for left and right channels
  • Select “Done” button and you’re all set.

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

How do I set my software’s I/O buffer?

The I/O Buffer setting found in most audio software is one of the most crucial, but often ignored, settings in a Mac-based recording system. When choosing a buffer setting, a compromise between the latency through the application and the amount of computer processor power accessible to the application must be made.Latency– the slight delay between the moment you play a note and hear it in your headphones after conversion and processing.

A lower buffer setting results in lower latency but less available processing power. If the application can’t access enough processor power, processor overruns may occur, resulting in audible clicks and pops or error messages that interrupt playback and recording. A higher buffer setting, on the other hand, results in greater amount of accessible processor power (i.e. less chance of overruns) but increases the latency. Determining the best setting requires some trial-and-error in order to find the best compromise.

Keep in mind that as tracks and plug-ins are added to a software session, processor requirements increase. Thus, the buffer setting that works during the early stages of a session might result in processor overruns during later stages. The best strategy is to set the buffer to a lower setting during recording and accept certain limitations on plug-in usage, and then raise the buffer during mixing to utilize the computer’s full processor power when latency isn’t an issue. With the processing power of today’s Macs, you may find that adjustment of the buffer isn’t necessary, and you can leave it at a setting for low latency and still access a sufficient amount of processing power when adding tracks and plug-ins. If you do encounter clicks, pops or software errors, don’t hesitate to experiment with the buffer setting. Please consult the section on Working with GarageBand, Logic and Mainstage to determine how to se the I/O buffer setting is found in your audio application.

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.


What is the maximum current capacity of the 48V phantom power? Will it handle any microphone?

Any Apogee product that includes microphone inputs with 48v phantom power is designed to handle loads up to a complete short, or 14.1 mA. This will properly power any microphone.
