Read full description

Replicant 3 is a real-time audio slicing and mangling effect, the third generation of the plugin that started the genre in 2007. Feed it any audio and Replicant's sequencer captures, loops, reverses, and re-slices it on the fly, layering in delay, filtering, panning, ring modulation, and bit-crushing to turn predictable tracks into something unpredictable. Version 3 is a ground-up rebuild with an all-new sequencer engine, expanded effects, and a redesigned interface that makes programming complex slice patterns fast and intuitive. SEQUENCER ENGINE Program 3 to 16 steps per measure with multiple step-size modes, from dotted notes through nontuplets. Build rhythmic patterns that go well beyond straight time. Per-step probability, direction (forward or reverse), and effect routing let you create patterns that evolve and surprise. FOUR SLICE EFFECTS The original Stutter capture-and-repeat is joined by three new modes. Delay adds rhythmic echoes to sliced audio. Redukt applies bit-crushing and sample-rate reduction for lo-fi destruction. Ring Mod adds metallic, inharmonic tonal coloring to any slice event. ENVELOPE CROSSFADING Smooth transitions or hard-gated rhythmic chops on every slice event. Control the attack and release shape of each captured buffer for precise dynamic control. MANUAL AND MIDI TRIGGER Bypass the sequencer entirely and fire slices on demand. Manual trigger mode works with touchscreens for live performance. MIDI trigger lets you drive Replicant from a controller, keyboard, or DAW automation. REDESIGNED INTERFACE A visual step sequencer puts your entire pattern on screen at once. Edit steps, assign effects, set probabilities, and adjust parameters without menu-diving. CROSS-PLATFORM PRESETS XML-based preset manager with presets compatible across all Audio Damage plugin formats and operating systems. SOUND DESIGN IDEAS Sequence stuttering vocal chops with per-step filter sweeps. Build glitched-out drum fills by randomizing slice direction and bit-crushing depth. Layer ring modulation on sustained pads for metallic, evolving textures. Use MIDI trigger mode to fire slices manually in a live set. Program polyrhythmic slice patterns with odd step counts against 4/4 time. Run full mixes through Replicant on a bus for controlled chaos breakdowns. AUv3 compatible. Runs standalone or hosted in AUM, ApeMatrix, Audiobus, Cubasis, GarageBand, and other AUv3 hosts on iOS 11 or newer. From Audio Damage, making creative software for discerning musicians since 2002.
