This is the first part of Keeper of Mummy Omnisphere2 Pack.
It is consist of 52 Patches, 17 our own Soundsourses from hard synths.
It is focused on LowEnd spectrum of sound and composed to get all you need in your Bass track.
All presets are based on MOOG hard synth. What is better for that purposes ? I don't know.
Not bass only. There are such beautiful Pads in this project like some MOOGs are Poly synth. PolyVoyager f.e..
