Sometimes you might want the Omnisphere standalone to be the only thing on your screen. Fullscreen mode hides your desktop and places Omnisphere on a simple black background for a clean look with no distractions.
Select “Fullscreen” from the View menu or simply hit “Command–F / Control-F” to enter Fullscreen mode.
Hitting “Command–F / Control-F” again or pressing the ESC (Escape) key exits Fullscreen.
TIP: By using Fullscreen in conjunction with Magnify, you can set up a large, easy-to-see interface.
