We are happy to announce version 1.7 of Late Replies, our creative delay and reverb plug-in that combines built-in and third-party effects within customizable delay lines and feedback loops for advanced echo, reverb and sound design applications.
The update delivers significant performance gains, alongside smoother preset transitions and a new quiet update mode for seamless delay time changes without pitch shifting artifacts.
Version 1.7 also introduces new tools for managing presets and third-party plug-ins, expanded MIDI control capabilities, and numerous enhancements to the user interface, compatibility, and overall user experience. A complete list of new features, improvements and fixes is available below.
Blue Cat's Late Replies 1.7 is available now for Windows and macOS in VST, VST3, Audio Unit and AAX formats. To celebrate the release, we are offering a 20% introductory discount until June 30, 2026. The update is free for existing customers and available from their original download location.
