At present, the Cortex Cloud does not have a marketplace feature. There is no officially supported way to sell your preset creations for preset creators like myself. The process works for sharing private presets is you have to befriend someone, then they can share private captures and presets with you.
I have a knack for creating clone presets based on famous artist sounds. Think bands like Monuments or Linkin Park, the kind of tones people want but might lack the knowledge to create themselves. So, I decided to build something called cortexpresets.com.
You choose the Quad Cortex presets you want, and then you get your purchases shared with you. It’s a hokey pokey process at present, but it’s the only way. All you do is befriend my account on Cortex Cloud, provide your Cortex Cloud username, and share the presets with you.
While I will be selling presets, I will also continue to create free presets. When the official marketplace is launched, people will be migrated over to the new marketplace.
