K7D vs BLEASS Granulizer
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
K7D
This app offers a vintage tape delay effect with analog emulation and modern controls. It recreates classic hardware echo machines for a warm, characterful sound. Use it standalone or as an AUv3 plugin in iOS DAWs.
- Analog modeled dual playhead delay
- Modeled microphone input with saturation
- Normal and Ping Pong modes
- High pass and Low pass feedback filters
- Powerful LFO time modulation
- BPM syncable delay time
- MIDI delay time modulation

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

BLEASS Granulizer is an innovative granular effect processor crafted for musicians, producers, and sound designers who want to transform incoming audio signals into rich, evolving textures and immersive soundscapes. It works by slicing audio inputs into small "grains" and reassembling them through real-time modulation of different parameters that you can visualize thanks to a 3D visualizer: Modulate - Volume - Pan (represented by width in the visualizer) - Size ( = grain’s duration) - Density ( = frequency of grains generation) - Offset ( = the amount of time between record and play represented by the depth in the 3D visualizer) - Backward/Forward Playback Direction - Shape ( = grain’s envelope, represented by the height dimension in the visualizer) - Warmth ( = strength of the distortion applied to the grain) - Tune ( = grains can be pitched up or down according to different modes: “Fine” / Chromatic / Major / Minor / 5th / Major 7th / Minor 7th / Octave. The amount of randomization can be set with the “dice” knobs. Density, grain size, and offset range can be freely synced or beat synced to the host’s tempo. Touching and holding the visualizer modifies pan and density. BLEASS Granulizer takes up to 4 sources from different busses as inputs (compatible host required such as AUM). When multiple busses are on, each grain is randomly extracted from one of the available sources. BLEASS Granulizer is your unique granular texture effect for reshaping any audio source into a dynamic granular soundscape in ways you've never imagined.

Verdict
The clearest difference is update cadence: K7D at every 3 months against BLEASS Granulizer's every 26 months. K7D also leads on price ($3.99 vs $6.99) and review sentiment (80% vs 67%). BLEASS Granulizer's advantage is rating (4.9 vs 4.6) and iOS requirement (12.0 vs 17.0). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
K7D costs $3.99 and BLEASS Granulizer $6.99 up front. Neither carries in-app purchases, so what you see is what you pay.
BLEASS Granulizer holds the better App Store score, 4.9 against 4.6. Both are backed by a comparable volume of ratings — 79 and 39 respectively. Written reviews complicate that: 80% of K7D's written reviews are positive against 67% of BLEASS Granulizer's, so the app with the better star average is not the one people write more warmly about.
K7D ships an update every 3 months, BLEASS Granulizer every 26 months. The most recent releases landed on September 22, 2026 and September 24, 2026 respectively.
