Setup

To control Omnisphere using the APC Key 25 mk2, you’ll need to do the following:

  1. Connect the APC Key 25 mk2 to your computer via USB.
  2. Enable the APC Key 25 mk2 as a MIDI input device in the host software you’re using (DAW, Standalone, etc.).
  3. Activate the APC Key 25 mk2 Hardware Profile in Omnisphere 3 or later.

HOST CONNECTION

  • Open your host (DAW, Standalone, etc.) and make sure the APC Key 25 mk2 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 “Akai > Akai APC Key 25 mk2” to activate the APC Key 25 mk2 Hardware Profile.

TROUBLESHOOTING

Not working? Here are some things to try:

  • Is your DAW receiving MIDI from the APC Key 25 mk2?
  • Make sure your DAW is configured to correctly route the MIDI output of the APC Key 25 mk2 to the MIDI channel assigned to the desired part in Omnisphere.
  • Are you using the APC Key 25 mk2 as a “Control Surface” for Ableton Live? If so, you’ll need to change the knobs on the APC Key 25 to “Device” mode so that the knobs can connect to Omnisphere. You can do so by holding down the [SHIFT] button and then press the [Device] button. If you’re still unable to control Omnisphere, you may need to disable the APC Key 25 mk2 as a “Control Surface” in Ableton Live’s “Preferences > Link/MIDI” settings page.
  • If you are using the Omnisphere standalone host, make sure the MIDI output channel of the APC Key 25 mk2 matches the MIDI channel of the Omnisphere Part you want to control.
