## What is sqrt?

SQRT is a multitouch sound board sample player. 
Tap on the items to trigger different sounds. Drag a triggered sound around the surface to change its parameters. Use the two buttons on the side to change the way how you can play / trigger the sounds.

With the pro version you can load in your own sounds (using iTunes or AudioShare) and create your own grids!

SQRT comes with a specially designed set of (glitch) sounds by composer/sound designer Ctrl-t (aka Jan T.) and are an incarnation of one of his recent (live) pieces. If you want to use your own sounds, get the pro version!

What is special about SQRT?
The sounds can be triggered from one point on the screen but the playback behavior can be manipulated over the entire screen. For each 'trigger point' there are snapshots of parameter settings spread across the playing area. The playback behavior is changed by interpolating between these presets. Currently the presets define pitch, loop start and loop length.

## Key features

- Multitouch sound triggering
- Drag-to-manipulate sound parameters
- Load custom sounds (Pro version)
- Create custom sound grids (Pro version)
- Interpolate between parameter presets
- Includes curated glitch sounds

### 2/5 — Pro Version not unlocking

*2023-08-16, version 1.7*

I tried multiple times to unlock it, but it just keeps processing the request… what gives?

### 1/5 — Nice idea but...

*2020-02-05*

This app is cheap, and has a whole load of excellent glitch sounds, as well as an innovative way of accessing them. Unfortunately though, having upgraded to the ‘pro’ version it is an insta crash for me on my iPad Air 2018 running 13.3.1 in Audiobus, AUM, or Audiobus linked into AUM. It will run standalone and I can record the samples out on my old iPad, so I’ll live with it, but it is such a shame that this app just can’t live up to its promise. Dev advised, and I’ll adjust the score if anything changes.

### 3/5 — Not working with Audiobus, AUM!!!
