Why Can't I Purchase any Sonic Extensions?
Sonic Extensions is an incredible line of amazing products for Omnisphere built by Spectrasonics.
Omnisphere 3 (or version 2) must be registered to your user account as well as installed and authorized on your computer to be able to purchase any Sonic Extensions.
Sonic Extensions are not compatible with Omnisphere version 1. If you have Omnisphere 1 and would like to upgrade to Omnisphere 3, you can purchase an upgrade from any of our resellers near you for the best deal (Sweetwater, Guitar Center, Sam Ash, or click here to find other resellers near you). Our resellers also have the best deal on brand new purchases of Omnisphere 3.
