## What is GrainProc?

GrainProc is a real-time granular synthesizer with which you can create new sounds and musical textures by affecting your voice, your instrument, or any input from AudioBus. 2 grain engines run in parallel, allowing you to layer two sounds and create rich textures, even as a solo performer!

Features:
• 2 Granular synthesizers running in parallel
• Waveform representation of the sound allowing you to touch where you want the sound source to be
• Sliders to control dry volume, wet volume, feedback level, and grain density
• Visual level monitors of the dry, wet and feedback levels
• Simple enough to be used with your feet! We discourage using your device with your feet, though it has been used that way for public performances!

## Key features

- Real-time granular synthesis
- Two parallel grain engines
- AudioBus input support
- Waveform sound source manipulation
- Control over volume, feedback, and density
- Visual level monitoring

### 1/5 — Rubish

*2025-01-31*

Doesn’t work, at all. Apple, get rid of this trash.

### 5/5 — Still a great little app

*2019-11-21, version 4.4.3*

I love this app and still use it lots for my ambient electric mandola stuff. I’d love it to be udated for AU compatibility; would hate to see it abandoned.

### 1/5 — Rubbish

*2018-12-16, version 4.4.3*

Up to now, just opened it and find that it is nothing more than a noisy piece of C..P...!

### 1/5 — Does nothing

*2018-08-19*

iOS 11.4.1, no sound, unless there’s some secret button

### 3/5 — Likely needs an update

*2017-09-28*

But, still cool. I’ve got a white block to the right of the blue page, and I’m not sure why it’s there. My install has never animated as it does in the demo videos. I’ve re-installed. No change.

### 5/5 — Uh huh huh huh uh h u uh huh

*2017-07-13*

Love it.  Make percussion ethereal.  Nature becomes a sonic temporal galaxy. A voice becomes a force.  Or, oops, you blink and Alice kicks you out of the rabbit hole. Until next time...

### 4/5 — Simple, Immediate, Gratifying

*2016-12-31*

Just picked this back up after using other granular apps, and the simple interface, with immediate understandable interface feedback, was gratifying. Not a substitute for other granular tools, but well worth having in the toolkit.

### 3/5 — ?

*2016-06-09*

How do you change sound input- like from my music rather than mic..

### 2/5 — Unsure

*2015-09-30*

Pretty lame that I have to write a review before I can see the info section.

### 4/5 — Good idea, getting better

*2015-08-01, version 4.1*

As promised, the latest update improves pass through sound drastically. GrainProc is now a nice addition to the toolkit of any sonic dabbler. The ability to reverse what's going on would be a nice addition, nest time.
