In Omnisphere, a Part can be thought of as an entire synthesizer, complete a multitude of parameters: oscillators, modulation routings, FX etc. A Patch is a snapshot of settings for those parameters and is loaded into a Part. A Patch is the most commonly used type of sound in Omnisphere.
Patches can range from a very simple signal path, utilizing a single oscillator in one Layer, to incredibly complex virtual connections, with all four Layers combining to create an entire soundscape at the press of a single note.
Omnisphere comes with a vast factory library of Patches that is regularly updated with new sounds. Users can also save custom Patches or import Patches available in third-party libraries or those created by other Omnisphere users.
Omnisphere has eight Parts, which means you can load up to eight different Patches in a single instance and play them simultaneously in a variety of ways.
This multi-timbral functionality leads to the top of the Omnisphere hierarchy, the Multi.
