### 5/5 — Great simple ez app

*2026-07-19, version 3.1*

It’s cool the dev is keeping this foundational sequencer around.  All the apps rock at Beep Street. This is an OG.

### 5/5 — Updated at last

*2026-04-14, version 3.1*

Well done!
Thanks.


Sadly, no longer loading properly -  maybe one day it’ll get updated?!?

### 5/5 — Thank you for updating

*2026-04-14, version 3.1*

Good dev keeps the old apps awesome

### 5/5 — Another State of Mind

*2025-12-01, version 3.0*

Even though this is an older app, I got hooked by it when I first started messing around with it.  This app and all (yes ALL) of the IAPs are worth it.

This is just one approach to making music, but it’s one that will really get you to thinking differently, especially when you apply effects.  Or how you choose to place different drum parts.  Linear drumming works great for this!  The biggest challenge is allowing enough room for chords, if you use them, as they require a track for each note of the chord.  

This app is so much fun.

### 3/5 — One of the best

*2025-11-23, version 3.0*

Sadly, no longer loading properly -  maybe one day it’ll get updated?!?

### 1/5 — Unsupported?

*2025-10-26, version 3.0*

Sadly, as I note is the case for another user, this app will no longer load on my iPad which I can only assume is because the developer has abandoned it and it is no longer compatible with the latest Apple software. It is sad for many reasons. I appreciate it is an old app but I’ve never found one better or more enjoyable to use, secondly I paid for all the ‘sound packs’ - not a fortune it’s true but still money now wasted. Worst of all, I’d composed some stuff in the app which, unless it is resurrected, is now gone forever. It was a five star app which is now unusable. Not happy.

### 5/5 — Bring it back 🙂

*2025-09-01, version 3.0*

This is such a unique sequencer, what a shame it has not been updated in a long time and doesn’t work on my iPad

### 4/5 — Presqu’un sans faute

*2025-07-27, version 3.0*

Alors là je suis scotché, incroyable cette app, un pixitracker avec entre autre la possibilité de mettre des panoramiques sur les samples ce qui est pas possible dans pixitracker. Je cherchais un truc comme ça depuis longtemps, et gratuit en plus c’est incroyable… et bien sûr pas de plantage, pas de lag…
Par contre il n’y a pas de background audio et ça c’est vraiment dommage, c’est pas lié à l’ancienneté de l’app car par exemple sur caustic 3 qui n’est plus sur l’app store on peut. J’avais l’habitude sur d’autres app de lire mes paroles dans « Notes » pendant la lecture mais là je ne peux pas, et pour lire un autre morceau aussi qui vient d’une autre app, obligé d’attendre la fin du morceau sur isequence avant de passer à l’autre donc pas possible d’enchainer rapidement pendant un concert sans faire un blanc, vraiment dommage il manquait que ça…

### 2/5 — Needs bugfixinf

*2025-06-07, version 3.0*

4th a is better err than dram on but it has a bugx

### 5/5 — Crashes repeatedly on start on iPad Pro.

*2025-05-21, version 3.0*

Crashes every time on iPad Pro running 18.4.1 iOS. I understand that it is hard to keep updating all the apps, especially as old as this one. Maybe it’s time to officially retire it to spare the frustration?
