Here's what they say:
Toxic Omnisphere is the first library created by someone other than John Lehmkuhl that is being sold exclusively through PlugInGuru.com. I am very happy to introduce all of you to Seth Norman. He's been helping here at PlugInGuru for almost a year now. He's done many of the cool kits in the R2 and R3 updates for MegaMacho Drums. He created demo sequences for Rotten Razor and Omniverse III: Aurora. He was also one of the 5 programmers that created grooves for the iZotope's BreakTweaker version of the MegaMacho Drums library. Everything he's touched has turned out golden so it was time to invite Seth to make a library of patches for Omnisphere.
Toxic Omnisphere takes the concept of bold, "In Your Face" synth patches where the Modulation Wheel does evil and nasty things to the sound that was first pioneered on Toxic FM8 and re-invents Omnisphere to be a complete evil task-master with waveforms and distorted resonant sounds like you've never heard come from Omnisphere before. These are sounds that will re-define how you can use Omnisphere. Taking you deeeeeep into the world of cutting edge EDM (whatever that is) genres and beyond.
Toxic Omnisphere is available for the introductory price of $25 until August 1st, 2014.
