### 1/5 — Doesn’t Work As Expected

*2024-12-03, version 1.2.2*

I wanted to use this in AUM but it doesn’t show up as a usable Audio Unit. Also, the sample time is limited to 3 minutes max, which isn’t what I need it for. THIS APP DOES NOT ALLOW REFUDS SO BUYER BEWARE!!!

### 5/5 — Still amazing in 2024

*2024-11-26, version 1.2.2*

Just bought it and this thing screams for jungle and IDM, experimental industrial etc. Really great way to use my field samples and drum kits. The guy who said it has poor audio quality is wrong. It’s crystal clear and really inspiring. Use it with AUM and Inter-App Audio to add your own effects to really go wild. Pair this with Replicant 3 and FAC Smash to see what I mean! Absolutely great.

### 5/5 — Love it!

*2023-12-01, version 1.2.2*

Please make available on all Apple Silicon.
Would LOVE to use this on a desktop for laptop.

### 5/5 — Unreal

*2023-10-09, version 1.2.2*

It is hard to describe what this app does, but the sounds you get out of it can be quite unreal. SECTOR-ize your sounds in AudioShare, I promise it will blow your mind. 🤯

### 5/5 — Brilliant app

*2023-06-26, version 1.2.2*

Please make this available on the App Store on the mac.

### 5/5 — Long time favourite that never ceases to inspire

*2022-12-31, version 1.2.2*

Brilliant all round app. Quality, integrations with importing audio and finely tuned controls to glitch away for hours. Brilliant for creating base loops to then import to Logic to further too. Triggering certain samples allows you to perform additional structures in too. Great app. To the developers, thanks and…please make this available on MacOS too if possible.

### 5/5 — Amazing program

*2022-12-20, version 1.2.2*

I had it for a couple of years, and didn't mess with it much because I didn't read the manual and I found it to be sort of interesting, but not particularly useful for anything musical. Today I read the users guide and I'm figuring it out a bit. It's amazing, and addictive. Not for those afraid of chaotic rhythms.

### 5/5 — Revisiting this several years after buying

*2022-11-25, version 1.2.2*

And it’s even more fun!

With iOS Music MIDI and audio tools making it easier to generate repeating loops, it can be tempting to devote way too much time to arranging clips in order to get music with enough variety that it’s worth zoning out to for a few hours. Sector last you take that catchy motif and twist it into an ever evolving groove.

Still wishing for iPhone and AU versions! I’d love to be able to run multiple instances of this in AUM and let simple loops intertwine for hours on end.

### 5/5 — My god it’s beautiful

*2022-10-27, version 1.2.2*

Sector is a gem, the only thing I can critique is the fact it isn’t AUv3. If I could run an orchestra of ‘Sectors’ that would be a glorious disaster.  Thank you for such a timeless tool you son of a synth.

### 5/5 — Another great one!

*2022-09-12, version 1.2.2*

Kymatica always killin’ it!
