36 real-time analog-modeled plugins included – The plugin library consists of emulations of most coveted and hard-to-find studio analog gear from around the world. The collection spans from a rare Austrian-born EQ to legendary British solid-state processing. A growing library of expansions is available to you in the Antelope software store.
