Studio One Setup & Troubleshooting: Impact GXP

Impact GX/LX Mini & GXP Support

This page is applicable to the following products: Impact GXP49, GXP61, and GXP88.

Important: Make sure that you install the Studio One integration files for Impact GXP series after installing Studio One. If you accidentally ran our installer before installing Studio One, Studio One will not recognize your Impact GXP series keyboard. In that case, simply run our latest Studio One support installers again. You can find the latest installers on your Account page.


  1. With your Impact GXP series keyboard connected and powered on run the Impact GXP support installer you downloaded from the ‘My Account’ section of the Nektar website after registering Impact GXP. Here are those instructions.
  2. Now launch Studio One.
  3. From the Studio One menu navigate to ‘Preferences’ (in MacOS, image 1) or ‘Options’ (in Windows, image 4) and select ‘External Devices’.
  4. If your ‘External Devices’ window already shows two Impact GXP devices (Images 1 & 4) you are ready to go. Move on to step 8.
  5. However if you see only one or no devices you will need to click the ‘Add…’ button to add them manually.
  6. Choose the missing Impact GXP** Control and/or Impact GXP** Keyboard from the Nektar folder (Mac: images 2 & 3, Win: images 5 & 6) and click ‘OK’.
  7. Make sure the ‘Receive From’ & ‘Send To’ ports are set up according to the table below:
    MacOS: Send To Receive From
    Impact GXP** Control Impact GXP** MIDI2 Impact GXP** MIDI2
    Impact GXP** Keyboard Not connected Impact GXP** MIDI1
    Windows: Send To Receive From
    Impact GXP** Control Impact GXP** MIDIIN2(Impact GXP**)
    Impact GXP** Keyboard Not connected Impact GXP**

    Note: ‘Impact GXP**’ where ** represents the Impact GXP keyboard model you are using.


  8. Click ‘OK’ to close the ‘Preferences’ window.
  9. Create a new project or open an existing one.
  10. Press the play button on the Impact GXP keyboard to confirm that Impact is communicating with Studio One.


Studio One 5.1 and above
If you have already started Studio One 5.1, with an older version of our Presonus Support and encountered an error message or crash, please run the latest installer from your account page, then navigate to the External Devices menu in Studio One and remove any External Device configurations for Nektar devices. After clicking the ‘Remove’ button, click ‘No’, so that the controllers files are not deleted. Then restart Studio One, so that the controller can be detected as if it were the first time.

If you were using your controller with Studio One 5.0.2 or earlier, please remove the devices from the ‘External Devices’ menu in Studio One, before installing this update.

If you cannot control Studio One’s included instruments or you are unable to use the Control Link system to assign controls from Instrument Mode, make sure that the ‘Impact GXP Control’ device is in focus. Every plug-in window has a drop down menu, in the upper-right corner, which allows you to select which controller is currently in focus. (See image)

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.

  • If you see your Impact GXP controllers in the External Devices window but transport and other control surface functions are not working, please reinstall the Studio One support files.
  • If you have manually removed your Impact GXP controllers you will need to reinstall the Studio One support files in order to use them Studio One again.
