- Knob 3 (CC#46) – Global Controls Filter Envelope Amount
- Knob 4 (CC#47) – Global Controls Vibrato Depth
- Knob 5 (CC#48) – Global Controls Ambience Amount
- Knob 6 (CC#49) – Global Controls Ambience Length
- Knob 7 (CC#50) – Global Controls Unison Amount and Detune
- Knob 8 (CC#51) – Global Controls Glide
- Fader 1 (CC#09) – Global Controls Amp Envelope Attack
- Fader 2 (CC#10) – Global Controls Amp Envelope Decay
- Fader 3 (CC#11) – Global Controls Amp Envelope Sustain
- Fader 4 (CC#12) – Global Controls Amp Envelope Release
- Fader 5 (CC#13) – Global Controls Filter Envelope Attack
- Fader 6 (CC#14) – Global Controls Filter Envelope Decay
- Fader 7 (CC#15) – Global Controls Filter Envelope Sustain
- Fader 8 (CC#16) – Global Controls Filter Envelope Release
- Fader 9 (CC#17) – Part Level
Setup
To control Omnisphere using the NTK-49, you’ll need to do the following:
- Connect the NTK-49 to your computer via USB.
- Set up the NTK-49 to control Omnisphere.
- Enable the NTK-49 as a MIDI input device in the host software you’re using (DAW, Standalone, etc.).
- Activate the NTK-49 Hardware Profile in Omnisphere 3 or later.
NTK-49 SETUP
Omnisphere relies on the second bank of knobs and faders and the factory default settings of a Scene on the NTK-49 while in MIDI Mode for external control.
Here’s how to set this up:
- First, enable MIDI Mode by pressing the [MIDI] button on the NTK-49.
Next, you’ll need to load a Scene.
- If you haven’t customized any Scene on the NTK-37, then you can move on to next steps under “HOST CONNECTION.”
- If you have customized one of the 16 Scenes on the NTK-49, you can simply load an unused Scene that has not been customized by long-pressing the [MIDI] button to enter the “Scene” settings, then use the 5-way master encoder to select the unused Scene.
- If you have customized all 16 Scenes then you’ll need to use NUX’s NTKEditor to reset a Scene back the factory default settings and then send that Scene to the NTK-49. See the list at the top of the page for the correct MIDI CC#s.
- Lastly, enable the 2nd Bank of knobs by pressing the [SHIFT] + [BACK] buttons.
HOST CONNECTION
- Open your host (DAW, Standalone, etc.) and make sure the NTK-49 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 “NUX > NUX NTK-49” to activate the NTK-49 hardware profile.

TROUBLESHOOTING
Not working? Here are some things to try:
- Is your DAW receiving MIDI from the NTK-49?
- Make sure your DAW is configured to correctly route the MIDI output of the NTK-49 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 NTK-49 matches the MIDI channel of the Omnisphere Part you want to control.
