Blue Cat Audio Late Replies Audio Plug-in Software

Delay for days! Create pulsing patterns, shimmering textures, and drones -- even add third-party FX with this powerful delay/reverb/multi-effects plug-in.

Blue Cat's Late Replies is a powerful delay, reverb, and multi-effects plug-in that can be indefinitely extended by hosting third-party VST, VST3, or AU plug-ins anywhere in the signal path.

With its unique topology, the plug-in is a full-featured delay machine with unlimited powers: both the 8 taps pattern module and the two nested feedback loops include plug-in slots that can host built-in effects or third-party plug-ins.

So it's not just about delays! The plug-in includes 29 built-in effects to further manipulate the delay lines: modulation effects, EQ and filters, dynamics processors, pitch and frequency shifters, waveshaper...

With the integrated ducker and its side chain input, ducking delays or reverbs has never been so easy.

Blue Cat's Late Replies is delivered with hundreds of presets producing many kinds of audio effects: classic delays, rhythmic or melodic patterns, reverbs, vintage echoes, shimmer effects, sci-fi sounds... Browse and edit them quickly with only a few parameters in "easy mode", or expand the user interface to "full edit" mode to create your own creative delays, reverbs, and effects, with complete control over the entire signal chain.

This plug-in includes several factories presets created by Sink and Hans Van Even.
