So here we are, my intention was to create my own guide for this topic. But why invent what already been invented:-) The web and youtube has it all.
I had begun creating my own templates from scratch and ran in to some issues. Took a search online and found alotta guides who helped me out.
Owners of Omnisphere can download a free template from Spectrasonics website. Link to site for authorized users
Here is a great guide, which also gives a free useable template for Reaper. Links to other sources below.
