So I've been in synthesis mood lately. I also like synthesis as a topic for videos because it's great, Usable info for you. In fact I think learning how to make your own patches is key to making your own sound. I think I put the producers that make their own sounds, sounds I want to re-create,In a different category than I do the producers that use the same old Nexus/Omnisphere sounds.
Don't get me wrong,I use Nexus, or any other pre-made patches, for that matter, as well. I don't, however,Lie on them.Also if you are a Nexus user this video will help you as well in order to understand the envelope parameters it features as well.
