Set up your audio device with Logic Pro

Focusrite ScarlettAdding a sound card can sometimes be tricky. There are lots of different manufacturers, all offering different functions and features, and finding the right one can be a challenge. Installing the one you’ve chosen can also be difficult.

Preflight check


  1. Have your “INSTALL CD” ready
  2. Your new interface at the ready with all associated cabling
  3. Some headphones or monitors to hear recorded audio
  4. Have a sound source to record, (e.g. A microphone, guitar pedal etc)

Getting Logic to recognise an audio interface is made a lot easier now that manufacturers include an install CD or download. If the install has never been completed, insert the Manufacturers install CD now. Follow the relevant instructions on the installer to make sure that the audio interface is recognised. Once the interface install has been completed, plug in the interface and turn it on if required.


Mock Installer


To check that the install was completed correctly, go to the applications folder in the finder.




Find the utilities folder within the applications folder


apps utilities


Once opened, find the “AUDIO MIDI SETUP” application


Audio Midi Setup


Once opened there is a virtual representation of how the computer sees the audio interface. Once installed, the sound card will be highlighted meaning that the computer recognises the audio interface. The main information contained here is related to MIDI information. It is possible from here to connect up any analogue instruments that are connected via MIDI to the interface.


M-Audio Pro Keys


The triangles located below the sound cardĀ enableĀ the user to make the midi connections required (or available) to replicate the virtual impression of the studio. Double click the new device that has been created to rename the device if desired.


Audio Midi Settings


Once happy, close the program by pushing CMD + Q. Now it’s time to turn the focus to Logic and ensure that it is able to hear any audio being passed to the recording interface. Find Logic pro and open it.


Open Logic


Logic will scan for the new audio device that has been added. It should be recognised but there are some additional checks to be made. Create a new blank project and add one audio track.


insert audio tracks


Once an audio track has been created, find the “INSPECTOR” icon and click the “PREFERENCES” icon that is located next to it. A number of options will be displayed.




Select the audio option and a window will open displaying the options for selecting an audio interface.


Audio Setup


If the audio device is is available to use, it will now be available in the preferences section displayed here. There are some important drop down menu and check boxes that will enable certain features if available on the recording device.


  1. Output device; this drop down menu will give the option of selecting the newly installed interface.
  2. Input device; this drop down menu will give the option of selecting the newly installed interface.
  3. I/O Buffer Size; lower buffer settings will mean less delay between playing an instrument and hearing the signal in headphones or monitors. Higher buffer settings enable more plug ins and instruments to be used, but mean that there is a delay between playing the source and hearing the effect or software instrument. When recording audio, always use lower buffer settings.
  4. 24 bit recording; If unchecked will mean that the computer records the audio at a lower bit depth. For higher audio fidelity, leave this field checked.
  5. Software monitoring; if unchecked, the audio being recorded will not be played back to headphones or monitors WHILE recording.
  6. Independent Monitoring Level; if checked, this will use different volumes on channel strips for recording and playback. This will enable the user to continuously mix a project without affecting the headphone mix being transmitted during recording sessions.

Once done, there is some advice available to create a template.
