- VST Sound
Steinberg's universal media management format – VST Sound – is a fundamental part of VST3, the latest version of Steinberg's industry standard Virtual Studio Technology.
By supporting VST Sound , plug-ins and instruments from third party manufacturers can be directly integrated into MediaBay – the media management system used in Steinberg's host applications. This integration makes the entire process of finding and working with any form of media file including audio, loops, VSTi presets, videos, MIDI parts and Track Presets, much faster and simpler.
VST Sound replaces SoundFrame, which was incorporated into previous versions of Cubase products.

- VST Sound Collection Vol. I
The VST Sound Collection Vol. I offers over 1.5 GB of new content, sounds and loops produced by top producers, including Yamaha, Sonic Reality and Big Fish Audio. It can be used royalty free by all Cubase customers.

- Sequel 2 and Sequel Content Set support
