## What is WaveCloud?

WaveCloud is an innovative granular synthesizer that offers powerful tools for manipulating and playing sounds. Granular synthesis divides an audio sample into tiny fragments, called grains, each typically a few milliseconds in length. These grains are then manipulated independently in terms of pitch, duration, position in time, and amplitude. Unlike traditional synthesis, the capability to manipulate tiny grains of audio offers enormous precision of sound control, transformation, and compositional possibilities.

WaveCloud offers a wide range of tools for experimentation – oscillator, LFOs, filters, envelopes, routing matrix, innovative WaveGlide and Orbit modules for grain movement, effects, MPE support, extensive waveform editing, customizable themes, MIDI CC control, aftertouch, audio pool manager, and 200+ presets to get you started.
    
Granular synthesis is extremely versatile and can produce a vast range of sounds and textures, from subtle, atmospheric sounds to complex, dynamic ones. WaveCloud offers dozens of parameters, enabling you to sculpt the sound grains in any way you wish – textural pads and atmospheres, time-stretched effects, glitchy and stutter effects, vocal and instrumental manipulations, granular synthesis percussive sounds, experimental effects, as well as microtonal and harmonic soundscapes.
 
WaveCloud features a drag and drop system for importing and exporting of audio files and presets. It has its own built-in Preset and Audio Managers to help keep everything in order. WaveCloud even features a fully-fledged zoomable audio editor along with a suite of tools to crop, fade, cut, copy, paste, and normalise your samples.
 
We include a morphing 3-state Oscillator to support the granular engine. The granular engine allows up to 50 grains per second per note, with grain lengths up to a second in length. Grains can be sculpted with our morphing envelope generator, manipulated with our LFOs, FEGs and VCFs,  and passed through lots of randomisation to keep things continually evolving.
 
WaveCloud also features two unique features for adding movement to audio grains. Orbit mode allows you to play sweeping patterns tied to the physical host tempo of your DAW, and WaveGlide is a sequencer with glides and fades from one location to another.
 
To top it all off, we include 7 built-in effects, delay, reverb, chorus, overdrive, phaser, resonator, and 8-band EQ. The resonator controls per-note feedback and dispersion for amazing MPE effects.
 
WaveCloud is not only a deep and powerful granular synth but also a fun way to create many incredible sounds.

### 3/5 — Can be better

*2026-07-26*

Good functions, bad GUI.

### 5/5 — Brilliant as always

*2025-09-07*

Paul’s apps are always a cut above and this is no exception. It took a lot of sinking in because I’m getting old, but I’ve got the hang of it now.
The Waveglide and Matrix features are superb.
Well done my fellow Yorkshire Brother.

### 5/5 — Fantastic!

*2025-01-18*

One of the best granular synths I’ve ever used. Well thought out, sounds great and just an overall pleasure to use. Thats not easy to come by in granular synths. Thanks!!

### 1/5 — Terrible auv3 implementation and rubbish on iPhone

*2024-09-22*

Does not load up in GarageBand, why not? Have not bought a music app in years… so I pulled the trigger on this as it looks great in videos, something for ambient soundscaping.
Further, it doesn’t really work as a standalone, only fills half the screen on my iPhone so the controls are not accessible nor can you read anything descriptive 
What is the point of making an app universal if it won’t fill up the iPhone screen? Judging by the amount of apps this dev releases, it seems he is in a hurry and doesn’t consider aesthetics and placement a priority.
Asked Apple for a refund and won’t touch this devs apps again 
Be careful if you are an iPhone user

**Developer response:** Works fine in GarageBand, so I assume you are doing something wrong. This app is an AUv3 plugin and not a standalone app. It only runs in standalone mode to allow backup of presets. It works fine when loaded under a DAW. In my humble opinion you don’t deserve a refund as you haven’t contacted me for technical support. Apple really needs to check these claims are true before issuing any refunds.

### 5/5 — Another five star app

*2024-01-30*

This is just wonderful. I can’t find anywhere to ask a question though so I’ll ask here . How do I play just the raw sample on the keyboard? Thanks

### 5/5 — Fantastic

*2024-01-17*

This is great app. Not sure what the other review means by “engin sound”??   App is feature rich and sounds amazing.  If I have one gripe it’s to do with the drawing of the gui. Initially the interface is drawn small, you can resize but it never seems to fill the screen. This is mildly annoying.  But the app is 5 star for sure.

### 5/5 — imported samples…

*2024-01-10*

there is a bug. when a sample is loaded, you can‘t see it‘s waveform:(

### 5/5 — Powerful, and fun

*2024-01-10*

Love this app - as well as having incredibly deep functionality for playing and mangling your samples, the randomisation options also make it fun to create your own presets.

A very powerful tool for sound designers.

### 1/5 — Big big big problem with engin sound

*2023-12-25*

Big big big problem with engin sound 
this is really a big problem

**Developer response:** Would you like to elabourate on what might be the problem? You say there is a problem with the sound engine and then don't explain what the problem is?

### 5/5 — Better now!  Thank you.

*2023-12-19*

This synth is nice sounding!  The developer is quick, responsive, and has worked out a UI solution that will help with the app sizing…and it also seems like the knobs work better?  Kool!

There were some other improvements as well, making this synth even more desirable to use.

**Developer response:** I’ve added a new option to Settings called Force Full Screen. If you turn this off the interface will be more accessible on the iPhone allowing scrolling between the two parts of the interface. I really wasn’t sure if to allow this app to run on iPhone since it really does need the screen space, but I was hoping people would except the limitation and be thankful it was at least supported. Maybe in future I will have to reconsider adding support if it harms my review status.

Fixes an issue where starting a new recording immediately after launch did not make the editor visible.
Fixed an issue where Grain Wrap was not being saved with the preset/session.
When changing the exposed AU Position or grain position knob, it now updates all playing notes/orbit positions.
Grain size can now be adjusted in 0.1K steps.
Number of Grains per second can now be adjusted in 0.1s steps.
The Setting option Append Recording has now become Recording Mode (OVERWRITE, APPEND and LOOP).
You can now specify a record length as seconds or beats.
The MONITOR button now needs to be engaged to hear any audio passing through, where previously it would allow passthrough during recording.
Append Recordings, Record Mode, Max Record Length, Monitor and Monitor Mix are now saved with the session / preset.
Exposed the Hold option as an AU parameter.
The input Monitor has been made an AU parameter.
Monitor Mix is exported as an AU Parameter.
Added a new Live Mix Options window which can be accessed from the Open Window submenu or from long pressing the Record button.
The Live Mix Options has a Threshold and Monitor Mix knob to mix monitor vs WaveGlide output.

The new LOOP recording mode can be used to create some basic granular effects. Use in conjunction with Max Record Length and the Live Loop Options.

NOTE: If Recording Mode is set to LOOP, it will work as follows:-
1) If Record Start is set to IMMEDIATELY, it will continuosly capture a loop of set length.
2) If Record Start is set to AUDIO DETECT, it will capture a loop then enter ARMED state, waitiing to be triggered again.

Updated the manual and added links to the new videos.
