Omnisphere 3 Hardware Guide

Setting up the Masterkey 49

When using the Acorn Instruments Masterkey 49 to control Omnisphere, the knobs on the Masterkey 49 are assigned to the following Omnisphere parameters:

  • Knob 1 (CC#74) – Global Controls Cutoff
  • Knob 2 (CC#71) – Global Controls Ambience Amount
  • Knob 3 (CC#73) – Global Controls Vibrato Depth
  • Knob 4 (CC#72) – Global Controls Glide
  • Slider 1 (CC#07) – Part Level

Setup

To control Omnisphere using the Masterkey 49, you’ll need to do the following:

  1. Connect the Masterkey 49 to your computer via USB.
  2. Enable the Masterkey 49 as a MIDI input device in the host software you’re using (DAW, Standalone, etc.).
  3. Activate the Masterkey 49 Hardware Profile in Omnisphere 3 or later.

HOST CONNECTION

  • Open your host (DAW, Standalone, etc.) and make sure the Masterkey 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 “Acorn Instruments > Acorn Instruments Masterkey 49” to activate the Masterkey 49 hardware profile.

TROUBLESHOOTING

Not working? Here are some things to try:

  • Is your DAW receiving MIDI from the Masterkey 49?
  • Make sure your DAW is configured to correctly route the MIDI output of the Masterkey 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 Masterkey 49 matches the MIDI channel of the Omnisphere Part you want to control.
  • Are the knobs on the Masterkey 49 sending the correct MIDI CC messages to control Omnisphere? A simple way to check this is by recording knob movement in your DAW.

NOTE: If you need to change the MIDI CC#s of the knobs on the Masterkey 49, you can do so from the Masterkey 49 (for steps, please review the Masterkey user manual). An alternative is to factory reset the Masterkey 49. However, doing so will erase all user-saved data. If you’d like to continue with the reset, please turn OFF the Masterkey 49, then hold down on the [OCTAVE UP] and [OCTAVE DOWN] buttons while turning ON the Masterkey 49 and release the Octave buttons once you see the display light up with “888”. This will clear any user saved settings and return the knobs back to their default factory settings.
