All the instruments get improved browsers with a "Favorites" listing method of organization, a user-selected "Star Rating" for library sorting, and a Project Tag that ties any sound to a particular project.

Sonic and operational improvements include new synthesizer filter algorithms including 12dB/24db low pass/band pass/high pass configurations for Omnisphere and Trilian, and a new Sample File Server function that uses RAM outside the 32-bit memory limit of MAC computers running 32-bit hosts such as Pro Tools for loading Spectrasonics patches, allowing more plug-ins to run simultaneously than previously possible.

Version 1.3 adds: Latch performance freezes notes from any part in Live Stack mode; Trigger mode allows Omnisphere and Trilian parts to be synchronized and quantized in real-time performance; Sustain2 offers more realistic Rock-style bass playing from Trilian; Envelopes now have Groove Lock™ feature; and there are 121 new Omnisphere patches and 17 new "produced" Trilian Bass Multis and Patches.

The free iPhone app called Omni Live that turns an iPhone or iPod Touch into a wireless remote control for Omnisphere's Live Mode page. Other additions: triplet and dotted rhythmic resolution for Arpeggiator, numerous compatibility and support improvements for Apple's recent Logic 9.1 update and 64-bit memory addressing, and Vienna Ensemble Pro 64-bit support.
