S-Gear standalone on the MAC will only recognise devices that report both inputs and outputs.  Some audio interfaces report inputs and outputs as seperate devices, some only provide audio input.

The solution is to create an Aggregate Device using the Audio MIDI Setup utility.

The following Apple support article explains how to set up an Aggregate Device:

The steps are as follows (this may vary a little between different versions of OS X):

  1. Run Audio MIDI Setup from the Utilities folder.
  2. Use the '+' button to create an aggregate device, name it something useful by double clicking on the default name.
  3. Add the external interface as your input device.
  4. Add the output device (use the same device if it supports output too, or use the internal spaeker or some other device).
  5. Make sure the audio settings are the same for input and output.

The new device should appear as an option in the S-GEAR configuration menu.

By creating an aggregate device you can create a virtual audio device with inputs and outputs that you specify. This is also useful if you want to use one device as an input and another as an output.

On a MAC running macOS 10.14 or later, make sure that S-Gear has permission to access the microphone:

  • Open MAC Preferences->Security and Privacy
  • Make sure that S-Gear is added to thes list of Apps allowed to access the microphone

Other possible causes of no audio through S-Gear:

  • Check the Left and Right channel enable buttons located beneath the input trim knob on the S-Gear user interface.  If your guitar is plugged into the left channel of a stereo pair, ensure that the left channel enable button is enabled.
  • Check the audio driver settings and audio routing configuration.  On the Audio Device tab, Device status should indicate 'Running' and the Audio Routing tab should be configured with the correct input and output routings according to the selected audio interface.

    For more information on Audio setup, please refer to the Getting Started section in the S-Gear User Manual.


The following steps will clear the S-Gear Audio Settings in the registry.  This may help resolve problems loading/starting an ASIO driver.

  1. Close S-Gear

  2. Click the Windows search icon and type ‘regedit’, open Registry Editor

  3. Navigate the folder tree to find the following registry key:

  4. Right click on the key and select ‘Delete’ from the menu
    (take care not to delete any other registry keys!)

The S-Gear2 key will be recreated next time you start S-Gear.
