This version of Resonance comes with the following changes: - New sleep timer: We received some feedback and added a sleep timer to Resonance (Pro feature) - Improved app appearance: We've added a splash of vibrant purple to make light and dark mode more exciting to use - Bug fix: Bulk exporting tool now allows you to pick reverb type as well (e.g. hall, stadium, spring, etc.) We hope you enjoy this update!
