Setup
To control Omnisphere using the Impact LX Mini, you’ll need to do the following:
- Connect the Impact LX Mini to your computer via USB.
- Set up the Impact LX Mini to control Omnisphere.
- Enable the Impact LX Mini as a MIDI input device in the host software you’re using (DAW, Standalone, etc.).
- Activate the Impact LX Mini Hardware Profile in Omnisphere 3 or later.
IMPACT LX MINI SETUP
Omnisphere relies on the default settings of “Internal” mode while the knobs are set to the Default page on Impact LX Mini for external control.
- Press on the [INTERNAL] button on the LX Mini, then press the [PAGE] button near the knobs until the “Default Keys” LED is lit.
HOST CONNECTION
- Open your host (DAW, Standalone, etc.) and make sure the Impact LX Mini is enabled as a MIDI input device.
OMNISPHERE SETUP
- Open Omnisphere and from the header, select the HW menu button.
- From the drop-down menu, select “Nektar > Nektar Impact LX Mini” to activate the Impact LX Mini hardware profile.

TROUBLESHOOTING
Not working? Here are some things to try:
- Is your DAW receiving MIDI from the Impact LX Mini?
- Make sure your DAW is configured to correctly route the MIDI output of the Impact LX Mini to the MIDI channel assigned to the desired part in Omnisphere.
- If you are using the Omnisphere standalone host, make sure the MIDI output channel of the Impact LX Mini matches the MIDI channel of the Omnisphere Part you want to control.
- Are the knobs on the Impact LX Mini sending the correct MIDI CC messages to control Omnisphere? A simple way to check this is by using MIDI Monitor by Snoize or recording knob movement in your DAW. See the list at the top of the page for the correct MIDI CC#s.
NOTE: If you need to change the MIDI CC#s of the knobs on the Impact LX Mini, you can do so from the Impact LX Mini (for steps, please review the Impact LX Mini User Manual). An alternative is to factory reset the Impact LX Mini. However, doing so will erase all user-saved presets. If you’d like to continue with the reset, please turn OFF the LX Mini, then hold down on the [OCTAVE UP] and [OCTAVE DOWN] buttons while turning ON the Impact LX Mini. This will clear any user-saved settings and return the knobs to the factory settings.
