Omnisphere 3 Hardware Guide

Setting Up the VI25

When using the Alesis VI25 to control Omnisphere, the Knobs on the VI25 are assigned to the following Omnisphere parameters:

  • Knob 1 (C#C20) – Global Controls Cutoff
  • Knob 2 (CC#21) – Global Controls Resonance
  • Knob 3 (CC#22) – Global Controls Filter Envelope Amount
  • Knob 4 (CC#23) – Global Controls Vibrato Depth
  • Knob 5 (CC#24) – Global Controls Ambience Amount
  • Knob 6 (CC#25) – Global Controls Ambience Length
  • Knob 7 (CC#26) – Global Controls Unison
  • Knob 8 (CC#27) – Global Controls Glide

Setup

To control Omnisphere using the VI25, you’ll need to do the following:

  1. Connect the VI25 to your computer via USB.
  2. Set up the VI25 to control Omnisphere.
  3. Enable the VI25 as a MIDI input device in the host software you’re using (DAW, Standalone, etc.).
  4. Activate the VI25 Hardware Profile in Omnisphere 3 or later.

ALESIS VI25 SETUP

Omnisphere relies on the factory default settings of any blank Preset on the Alesis VI25 for external control.

  • If you haven’t customized any Presets on the VI25, then you can move on to the next steps under “HOST CONNECTION.”
  • If you have customized any of the 25 available Presets on the VI25, you can simply load a new/unused Preset that has not been customized using the Preset UP and DOWN arrow buttons located below the LCD display.
  • If you have customized all available Presets on the VI25 then you’ll need to use the Alesis VI25 Preset Editor to make a Preset that matches each knob to the MIDI CC#s at the top of the page.

HOST CONNECTION

  • Open your host (DAW, Standalone, etc.) and make sure the VI25 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 “Alesis > Alesis VI25” to activate the VI25 Hardware Profile.

TROUBLESHOOTING

Not working? Here are some things to try:

  • Is your DAW receiving MIDI from the VI25?
  • Make sure your DAW is configured to correctly route the MIDI output of the VI25 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 VI25 matches the MIDI channel of the Omnisphere Part you want to control.
