NuRack is an AUv3 based multi-channel audio and MIDI effects processor with a difference, it actually allows you to design your own custom effects using the 80+ building blocks provided. You have full control over routing which allows you to create complex audio paths in series or parallel. You can choose whether to use the stock interface or create your own custom interface using the built in Interface Builder which allows you to concentrate your audio components into a single customized effect. NuRack can run in one of two modes. The first providing 3 customizable effects racks which can be switched (manually or via MIDI), providing seemless switching (i.e. delay trails linger whilst another set of effects are faded in). The second mode allows you to route audio through 3 independent audio racks. A generaous number of over 80 audio and midi building blocks are provided covering 12 different categories of effects. Here are just some of those included in NuRack: Modulation Effects: Chorus, Flanger, Phaser, Tremolo, Vocal Doubler, TalkBox, UniVibe, Leslie & Vocoder. Time Based Effects: Stereo Delay, Tape Delay, Reverb and Reverse Delay. Spectral Effects: Parametric EQ, Graphic EQ, PitchShift, Auto-Pan, Bit-Crusher, Tube Overdrive, Distortion, Harmony, Harmonic Exciter and SlowMo. Dynamic Effects: VelocityControl, Compressor, Multi-Band Compressor, Noise Gate, Gate, and Limiter. Filter Effects: MultiFilter, LP/HP Filter, Frequency Splitter, MultiBand Splitter, Classic Filters, Formant Filter, Ring Modulation and Shelf Filter. MIDI Effects: MIDI Harmony, MIDI Velocity, MIDI Randomizer, MIDI Monitor, MIDI Mixer, MIDI Pads, MIDI Control, Strummer, MIDI Recorder, MIDI Modulation, MIDI Remap, CC Monitor, CC Generator, PitchBend, MIDI Time Clock, and ChordToMidi. Generator Modules: Noise, Audio Clip Launcher, SoundFont Player, Virtual Flute, Virtual Clarinet, Virtual Brass, FM Organ, FM Rhodes and Analog Sawtooth Synth. Automation: TouchPad, AutoMate, Pattern Automation, and Visual LFO. You also provide the ability to split and combine audio signal using splitters and mixer modules as well as a number of visual elements such as VU Meters, LED Meters, Scopes, Graphs etc. Some effects such as phaser and flanger are usually controlled by an LFO, but this can be detached and automated remotely. There are a number of modules that allow auomation based on direct touch (X/Y Pads), Visual LFO, Pattern Automation, MIDI input (CC data), or peak/rms level detection. These automation modules can remotely control knobs and sliders throughout your rack. Simply create a new rack and start adding modules to it. These modules are generally wired up automatically but these connections can be manually routed. Once you have your sound as you wish you can use it 'as is', or switch to Interface Builder mode where you can combine all your modules into a single interface. Elements can be dragged, dropped, resized and coloured as required. Add your own labels, image logos and custom backgrounds before saving your custom component. Use the X/Y Pad to control your modulation effects by detaching their LFO's. Use MIDI CC data to automate knobs. Use the velocity of an incoming signal to control the cutoff/resonance of a filter (wah) or volume level of a gain control (swell), as NuRack expands, so do the possibilities. Features: ○ Over 80 categorised modules. ○ 3 Input / Output busses supported. ○ Audio & MIDI effect. ○ Lots of audio & MIDI automation options. ○ Seemless transition between racks. ○ Manual audio path routing. ○ Open in presentation mode (auto hides controls). ○ Interface Builder to customize your rack. ○ AUv3 plugin runs in MIDI and none MIDI mode. ○ Add your own Text/Heading and Image/Logos and backgrounds to your design. ○ Compatibility options for DAW's not supporting multi-channels. ○ Dark/Light Modes Checkout the YouTube channel 'Paul the MusicMan' for demos and tutorials of NuRack.

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: NuRack Auv3 FX Processor at every 3 weeks against BLEASS Granulizer's every 26 months. NuRack Auv3 FX Processor also leads on review sentiment (84% vs 67%) and chart position (#182 vs unranked). BLEASS Granulizer's advantage is price ($6.99 vs $12.99) and rating (4.9 vs 4.7). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
