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.


• 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.

I somehow got the impression that this would have Ableton Link

I swear the reason I was excited for this was Ableton Link being on the menu. I guess I was wrong.

The app has a lot of great tools. The sliders and quick key change options are great. Hold and Loop functions. And these aren’t even scratching the surface of the deep editing. But no Ableton Link kind of makes this an outlier in my app ecosystem

Developer Response ,

Hi, we are glad you like the app! Ableton link is supported through hosts like AUM or AB3, and it is on our list for possible features to include it in the app itself as well.

Genius Software

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

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!

Crazy good.

I’m completely puzzled why this app is not being mentioned all the time and does not get more popular. This app is an absolute dream come true, it’s capabilities are insane. There’s too much to mention here, you just have to experience it yourself.

All is working perfectly smoothly and the app is surprisingly intuitive. I can’t find a single bug aside from the User Manual getting stuck open on the iPad.

I do hear the pops that another reviewer mentioned and hope that this will be resolved.


I just wanted to say that I keep being amazed by this app. It’s been truly a joy to use. It keeps surprising me.

One feature I’d love to see being added is the ability to display note length / rates divisions at the top of the screen at all times. As it is now, they are not visible when the playing area is maximized, only when parameters of the instruments are displayed. It makes sense, I understand that there’s a conflict in displaying it at all time because when there are multiple cursors there may be multiple ways the playing area is split into note length columns, especially that touching multiple cursors is possible. Maybe then the ranges could be displayed in different colors corresponding to the given cursor or maybe the ranges are displayed only when only one cursor is playing?
