Mantis is a plugin that emulates a rare BBD (bucket-brigade device) delay/echo unit of the 70s, faithfully recreating its warm and analog sound.
Mantis is available for MAC, PC, and LINUX (VST, VST3, AU, AAX, CLAP, 64-bit only), and will also be available as AUv3 and Standalone on the App Store in a few days.
