lfoch vs GRDelay
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
lfoch
This app generates complex LFO waveforms with multiple outputs for creating "chase" effects. It offers two LFO generators with phase modulation, adjustable suboscillators, and waveform morphing. It can output MIDI control change values and sync to tempo.
- Dual LFO generators with phase/ring modulation
- Suboscillator modulation with waveform morphing
- Adjustable waveform rate, type, and range
- Output 1-16 MIDI control change values
- Tempo synchronization and AUv3 MIDI Effect support
- Two modes: 'perform' and 'edit'
- Randomize parameter values

lfoch is an experimental LFO generator that can create "chase"-like effect with multiple outputs from a single complex waveform It features: - 2 LFO generators with phase modulation / ring modulation: - Each LFO generators contains 2 suboscillators; one suboscillator modulates phase of another - For each suboscillator you can set waveform rate, waveform type (with smooth morph between sine, triangle, sawtooth and square waveforms), nonlinear curve (for overdrive-like effect) and minimum/maximum range - The result waveform is a multiplication of two generated LFO waveforms - You can use 1..16 points from this waveform to output as MIDI control change values - You can toggle the "playback" (phase change) of each generator with I/II buttons - You can randomise parameter values with "dice" buttons - App has two modes for live usage - 'perform' mode has larger waveform view and some selected sliders (if any) - 'edit' mode contains all controls on one screen - Each generator can be synchronized to tempo. In this mode the "speed" value runs from 4 quarter forward to 4 quarter backwards speed, the fastest value in this mode is 1/32 - When running inside AUv3 host the app uses host's transport. - "free mode" setting allows you not to follow the host transport lfoch is a standalone app and an AUv3 MIDI Effect. AUv3 effect supports parameter automation and preset saving inside host. Standalone version currently does not output MIDI in background mode.Note for AUM users:This application starts with 16 control change outputs from CC 0 to 15 on MIDI channel 1. AUM has default mapping of the CC #7 (volume) for each channel. Please keep this in mind when setting it up together.
GRDelay
This audio effect plugin creates unique sound textures by generating up to 16 stereo 'grains' from delayed input audio. It offers randomization of grain shape, delay time, and pitch-shifting for experimental sound design.
- Granular synthesis-based delay
- Up to 16 stereo grains
- Randomized grain shape and delay time
- Pitch-shifting and cascading grains
- Standalone and AUv3 compatible

GRDelay - Granular Random Delay Plugin (AUv3) GRDelay is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic Pro or GarageBand. Overview - What's a Granular Random Delay? GRDelay is a randomised delay effect that uses a similar approach to granular synthesis to generate sound. In GRDelay, up to 16 "grains" of stereo sound are created in realtime from delayed copies of the input audio, with control over the grain shape and delay time. There are also options to pitch-shift grains up an octave, and cascade the output from one grain into another. Shape, delay time and pitch-shifting can all be randomised to create some really unusual effects and textures. While GRDelay can produce sounds similar to existing pitch-shifted delays and even shimmer effects, the design is totally original, and to the best of my knowledge, quite sonically unique. I think GRDelay is really one of those effects you need to hear to believe, so please do check out the reviews and demos online. Please note, because there's a "whole lot of random going on" in GRDelay, it's not a good choice if you want a delay that can do tempo / clock-sync'd rhythmic delays. Perhaps take a look at PolyDelay which offers tempo sync to host and musical note length delay times. For more info and support please visit: www.waverley-instruments.com/robjackson

Verdict
The clearest difference is review sentiment: GRDelay at 100% against lfoch's 50%. GRDelay also leads on rating (5.0 vs 4.4) and price ($1.99 vs $3.99). lfoch's advantage is ratings volume (9 vs 3). On ads, in-app purchases, monetization model and device support there is nothing between them.
