K7D is a powerful and affordable, vintage tape delay effect plugin for iOS. K7D recreates the hardware echo machines of the past using Imaginando’s signature style of obsessive analog emulation, but with an enhanced level of control from a sleek, modern interface. Using this approach allows a whole new world of creative possibilities, while still retaining a warm, full-bodied analog sound, bursting with character and personality. To give K7D it’s distinctive analog flavour, we studied and analysed the tiny details of what makes classic hardware delays great, and painstakingly recreated every subtle nuance for a fantastically authentic sound. Available as a standalone app and audio unit plugin, you can use it digital audio stations for iOS such as Garage Band, AUM, Cubasis, Auria, Audiobus, etc. Features - 1ms to 1 sec. dual playhead analog modeled delay with noise, tape distortion and mechanical vibration models - Modeled microphone input with pre-amp saturation - Normal and Ping Pong modes - Optimized gain staging and saturation algorithms for very musical results - Delay time spread between heads and stereo width control - High pass and Low pass filter on feedback path - Powerful LFO bipolar time modulation with multiple waveforms (sine, triangular, saw, square, sample and hold and filtered sample and hold) and possibility of inverted LFO phase on second play head (for added stereo imaging) - Delay time syncable with BPM - Possibility of delay time modulation via incoming midi notes - Oscilloscope visualisation of audio waveform and LFO waveform - Built-in patch manager - Audiounit compatible
Replicant 3
This real-time audio effect processor captures, loops, and mangles audio on the fly. It offers advanced sequencing with per-step probability and direction, alongside four distinct slice effects for creative sound design. Control dynamics with envelope crossfading and trigger slices manually or via MIDI.
- Real-time audio slicing and mangling
- Advanced step sequencer (3-16 steps)
- Four distinct slice effects (Stutter, Delay, Redukt, Ring Mod)
- Envelope crossfading for dynamic control
- Manual and MIDI triggering
- Intuitive visual step sequencer interface
- AUv3 compatible

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.

Verdict
The clearest difference is rating: K7D at 4.6 against Replicant 3's 4.0. K7D also leads on update cadence (every 3 months vs every 18 months) and ratings volume (79 vs 4). Replicant 3's advantage is iOS requirement (12.0 vs 17.0). On ads, in-app purchases, monetization model and device support there is nothing between them.

K7D costs $3.99 and Replicant 3 $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
K7D holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: K7D has 79 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 80% of K7D's written reviews are positive against 67% of Replicant 3's.
K7D ships an update every 3 months, Replicant 3 every 18 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
