## What is Gestrument Pro?

The Interactive Gesture Instrument
Create music based on complex systems of musical rules and interactions. Using the motion of your fingertips, Gestrument Pro lets you play, improvise and compose with deeper levels of personal expression than ever before.

Play your music your way
Gestrument Pro lets you create something in-between a bespoke instrument and written piece of music. In other words, it’s an instrument made to play your own music in your own way.

Widen your musical comfort zone
Experiment with simple and advanced musical concepts such as microtonality, polyrhythms and much more using our modular system of highly tweakable musical generators. 

A next level Improvisational tool
By building patches based on the musical rules and properties of your own music, Gestrument Pro lets you improvise to it in real-time. Our Pitch and Rhythm generators make sure you’re always on time and always on pitch, no matter how you play.

Powered by the Gestrument Engine
Gestrument Pro is completely powered by our revolutionary Gestrument Engine, a system for generating music based on user interactions in real-time.

Based on the revolutionary Gestrument app from 2012, award-winning composer Jesper Nordin and leading iOS developer Jonatan Liljedahl (Kymatica) have completely re-invented their unique instrument and taken the concept to the next level.

Gestrument PRO takes everything we loved about the original Gestrument app and improves on its unique functionality while introducing a host of new features such as multi-touch, recordable automations, advanced scale editing and a unique system of highly tweakable modular generators that define rhythms and pitches.

Features:

• Powered by the Gestrument Engine.
• Up to 16 individual Instruments.
• Each Instrument can be controlled by any of up to 8 Cursors.
• Instruments can use internal high quality sounds or play other synthesizers or apps via MIDI.
• Modular swappable Generators for producing the rhythms and pitches per Instrument, each with their own set of tweakable parameters and settings.
• 8 performance sliders that each can control one or more parameters in the Instruments and their Generators.
• A highly flexible modulation system allows assigning Sliders and Cursor position/pressure to any parameter in the Instruments.
• Advanced microtonal Scale editor with several standard scales included.
• 8 Scale Slots for fast switching between scales and tonalities during performance.
• Sliders, Cursors and Scale Slots can be recorded into automated loops, or controlled via MIDI. They can also send MIDI.
• Supports Inter-App Audio and Audiobus, including host sync for following the hosts transport and tempo.

### 5/5 — Still amazing - easy to use, fun and powerful

*2026-01-01, version 1.2.1*

I’ve had this app for years but didn’t properly engage with it when I first got it. However, having rediscovered it I find it to be one of the best iPad specific music making apps out there. I’ve just hooked it up with Mass and it’s a whole world of fun. Being able to load up midi files then effectively sample the notes in a new musical way is wonderful. Belated thank you to the developer, and I hope you are able to keep this one going.

### 3/5 — GestrumentPro NotWork In AUM as IAA

*2025-10-11, version 1.2.1*

GestrumentPro, the AUM does not work well. Its interface is incomplete. In its lower left part, where the scales are placed, that we would like to work on, it does not show it. And in the configuration, of the instrument, I refer to the sliding list, when you want to get to the end of this, to select CC or CHANNEL, it is not fixed there, in case you want to make changes. The list is returned and does not display. I think that GestrumentPro is a very good app. to stop using it for this.

### 5/5 — Worth buying an iPad for!

*2025-05-29, version 1.2.1*

Worth buying an iPad for.

My No1 favourite app for live performance (the second being FigueMachineRubato)

Could do with some additional features like preset folders. I fear it not being further supported & developed.

### 5/5 — Hoping for an update…auv…still unique and incredible

*2025-03-25, version 1.2.1*

So good. Worth it.

### 5/5 — What a brilliant app

*2025-01-29*

Brilliant. Such an innovative and well thought out approach to music writing and performance. Perhaps more training videos would help to ‘on-board’ more users (and drive up sales).

### 5/5 — Genius Software

*2024-06-06, version 1.2.1*

I’m still amazed at the absolute genius behind this software. Is the user interface dated?… Sure, BUT for an app that hasn’t been updated in 3 years the dev’s initial creativity in how to make incredibly powerful software as simple and intuitive to use as this App is… I’m absolutely blown away. This has to be the single most underrated piece of software and I’m desperately hoping that an update gets dropped even if it’s just improved auv3 plugin support. My biggest fear is this App disappearing from the App Store because my live performances heavily incorporate this app. Thank you so much for creating such a brilliant app. Hope to see an update. Much love —  

 Original Review: This is the coolest music app I have found, but I’m afraid it might be abandoned now. Hopefully this will get a response from the developer, I’d love to see continued work on this app, there is nothing else like it

### 1/5 — …and this is supposed to make money?

*2024-03-24, version 1.2.1*

Then again, i’d probably pay some four year old to play a lot of random keys on his beginner casio keyboard and get the same result. I didn’t waste any money, just some good time off of my life, this app made me want to vomit on the spot.

### 5/5 — Why are some of the best apps ‘abandoned’? :-(

*2024-03-05, version 1.2.1*

Despite no auv3 and therefore not supported by logic this is still worth having.

Nice musical expression with no experience or music theory and possibilities to create your own musical playground with some.

Such a good use of multi touch, thanks for the fun. 🙂

### 1/5 — Click bait

*2023-07-23, version 1.2.1*

Waste of time.  Can’t even try it without first paying. Not even so much as a 1 minute free trial. Nothing. Nothing at all.  Would you buy a car without test driving it first?   If you had given a free 20 minute trial, I would have probably then bought it….as it is, you’ve just lost my money. Bad business.

### 5/5 — Awesome App, but afraid it’s abandoned

*2022-12-28, version 1.2.1*

This is the coolest music app I have found, but I’m afraid it might be abandoned now. Hopefully this will get a response from the developer, I’d love to see continued work on this app, there is nothing else like it

**Developer response:** We are still working on the underlaying tech, but right now we are not working directly on updating the app. That might change though - thanks for your support and always report any bugs you find!
