Setup
To control Omnisphere using the M50, you’ll need to do the following:
- Connect the M50 to your computer’s MIDI interface.
- Set up the M50 to control Omnisphere.
- Enable the M50 as a MIDI input device in the host software you’re using (DAW, Standalone, etc.).
- Activate the M50 Hardware Profile in Omnisphere 3 or later.
M50 SETUP
Omnisphere relies on the default settings of the External Setup named “000: KLC M1” for external control.
Please go through the following steps to activate External Setup KLC M1 on the M50:
- First, press the [PROG] button, and then press the [EXTERNAL] button (located near the 4 knobs).
- Access the “Prog P0: Play – Control Surface” page then choose “Setup (Setup Select).”
- Choose the first preset named “000: KLC M1.”
HOST CONNECTION
Open your host (DAW, Standalone, etc.) and make sure the M50 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 “Korg > Korg M50” to activate the M50 hardware profile.

TROUBLESHOOTING
Not working? Here are some things to try:
- Is your DAW receiving MIDI from the M50?
- Make sure your DAW is configured to correctly route the MIDI output of the M50 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 on the M50 matches the MIDI channel of the Omnisphere Part you want to control.
- Are the M50 knobs sending the default MIDI CC messages? You can check this navigating back to the “Prog P0: Play” > “Control Surface” page and reviewing the MIDI CC assignments for each knob.
