When using the Kurzweil PC3LE to control Omnisphere, the sliders on the PC3LE will be assigned to the following Omnisphere parameters:
- Knob 01 “Timbre” (CC#14) – Global Controls Cutoff
- Knob 02 “Mod” (CC#15) – Global Controls Resonance

Setup
To control Omnisphere using the PC3LE, you’ll need to do the following:
- Connect the PC3LE to your computer via USB.
- Set up the PC3LE to control Omnisphere.
- Enable the PC3LE as a MIDI input device in the host software you’re using (DAW, Standalone, etc.).
- Activate the PC3LE Hardware Profile in Omnisphere 3 or later.
PC3LE SETUP
Omnisphere relies on the default settings of Control Setup #126 named “Internal Voices” for external control.
- To load “Setup 126,” press the [Setup] button, then use the scroll wheel to step through the list of setups until you get to Setup 126 and press the [Enter] button on the numeric pad.
- Next, configure the PC3LE to send MIDI via USB by pressing the [MIDI] button and then change the “Destination:” parameter to “USB_MIDI.”
- Lastly, make sure the first bank of knobs is active on the PC3LE by pressing the [Shift] button to the left of the knobs until the LED indicator light next to the top row of knob labels is lit (next to “Timbre”).
HOST CONNECTION
- Open your host (DAW, Standalone, etc.) and make sure the PC3LE 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 “Kurzweil >Kurzweil PC3LE” to activate the PC3LE hardware profile.

TROUBLESHOOTING
Not working? Here are some things to try:
- Is your DAW receiving MIDI from the PC3LE?
- Make sure your DAW is configured to correctly route the MIDI output of the PC3LE 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 Zone 1 on the PC3LE matches the MIDI channel of the Omnisphere Part you want to control.
- Are the sliders on the PC3LE sending the correct MIDI CC messages used to control Omnisphere?
Here’s how to check:
- Go to the “MIDI XMIT” page by pressing the [MIDI] button and pressing the “XMIT” soft button.
- Highlight Control Setup”: “126 Internal Voices.”
- Press “EDIT” then select the “more” soft button.
- Select each slider one at a time and make sure they are assigned to the default MIDI CC#s listed at the top of the page.
