Logic Setup & Troubleshooting: Impact GXP, LX Mini & GX Mini

Impact GX/LX Mini & GXP Support

Here are the steps you need to go through to get Logic up and running with your Impact series controller.

Setup instructions for Logic 10.6 and later

The Impact GXP, Impact GX Mini or Impact LX Mini controller is compatible with Logic Pro X 10.6 (or higher) .


  1. Locate the ‘Impact_GXP_Apple_Support’ or ‘Impact_GX-LX_Mini_Apple_Support’ installer included with this package and run it.
  2. A dialog box will appear stating “This package will run a program to determine if the software can be installed”. Click “Continue”.
  3. If a second message appears, informing that an older version of Nektar DAW integration for logic was found, click here for instructions.
  4. Otherwise continue following the installer prompts until complete.
  5. Plug in your Nektar controller and make sure it’s switched on.
  6. Launch Logic.
  7. In Logic, a dialog box will appear asking ‘Do you want to automatically assign the controls of the Nektar “Impact…”?’
  8. Click “Auto Assign”
  9. The Control Surface window will appear showing the Impact GXP, GX Mini or LX Mini icon. Close the window.

That’s it, setup is now complete.

Troubleshooting with Logic 10.6 and later

If you do not see the message detailed in step 6, or if the Nektar DAW integration is not working following, complete these steps:


  • Open the ‘Logic Pro’ menu at the top left part of your screen and select ‘Control Surfaces/Preferences’.
  • In the window that appears, select the ‘MIDI Controllers’ tab. (see image)
  • Check the box in the ‘Auto’ column for your Impact controller.

Setup instructions for Logic 10.5 and earlier

Note: Impact GX Mini and LX Mini are only compatible with Logic 10.6 and later.


  1. Make sure Logic is already installed on your computer. If not, please install Logic first and open Logic at least once, before running the installer for Nektar DAW integration software.
  2. Download the ‘Impact_GXP_Apple_Support’ file from your Account page after registering your product. If you selected Logic as your DAW, you’ll find the link below your product registration.
  3. Run the ‘Impact_GXP_Apple_Support’ installer and follow the onscreen instructions.
  4. Plug-in your Impact keyboard and make sure it’s switched on (if you didn’t do so already).
  5. Launch Logic.
  6. Create a new Project or open an existing one.
  7. The Control Surface Setup window will appear to indicate that Logic has detected a new control surface. See image.

Troubleshooting with Logic 10.5 and earlier

If the controls/keys on your Impact GXP are behaving unusually or simply not working try this fix.

  1. Close any applications you have open.
  2. Open a Finder window.
  3. Open the ‘Go’ menu at the top of the screen.
  4. Select ‘Go to folder…’
  5. Type ‘~/Library/Preferences
  6. Click ‘Go’.
  7. Find com.apple.logic.pro.cs and move it to the trash (Important!)
  8. Empty the Trash.
  9. In the Finder go to //Applications/Nektar/GXP or //Applications/Nektar/Apple.
  10. Run the uninstaller located in that directory.
  11. Restart your computer.
  12. Start Logic and create an empty project (this is just so Logic creates a new cs file).
  13. Quit Logic.
  14. Run the latest installer (the latest installers can always be found on your Account page).
  15. Start Logic again.

You should now be able to control Logic’s transport functions using your GXP’s transport buttons.


Patch Changes
If you find that the [< Patch] and [Patch >] buttons don’t work when controlling a third-party plug-in, it’s likely because the plug-in uses it’s own patch browser. The Patch buttons on the Impact series control the patch navigation functions of the DAW, so you may need to save the plug-ins presets in your DAWs patch format, before you can use the Patch buttons on the Impact controller for patch navigation. You can find more information about saving patches in your DAW, in the documentation for that program.
