◆ A Modular Instrument for Music Production ◆

KRFT is a modular instrument for expressive music production that we built to challenge the two decade old paradigm of the multi-track DAW.

Designed from the ground up with a focus on live experimentation and expressive interactions, KRFT will inspire you to make music that would normally be out of reach.

Rather than being confined to a fixed interface KRFT lets you create a surface that suits your musical needs whether you're building an experimental groove box or composing an entire track.

Use it standalone with its powerful internal audio engine or with your studio & MIDI enabled gear, such as Ableton Live or Logic Pro X.


◆ Produce & perform from one expressive interface ◆
KRFT is a canvas for your musical ideas that can be controlled and interpreted on the fly. Recorded loops, custom samples, dials and more can all be controlled from one unified interface. This structure lends itself to live play, each performance being unique and instinctive.

◆ Craft your masterpiece – piece by piece ◆
Build your canvas from musical cells, each shape with a different behaviour. Loops provide the core of your composition and dials, morphs and fills allow you to add flair and excitement. Group cells to give your track structure ― build as much or as little as you need.

◆ Tweak and refine your sound ◆
KRFT is all about customizability. Editing your recordings or sequencing notes is quick and easy in the Matrix and fine adjustments to the sounds and cell interactions can be edited directly from within the app – no need for external software.

◆ Control other apps, software and hardware ◆
- Send MIDI from KRFT to any DAW e.g. Ableton & Logic Pro
- Sync up with other devices and apps using Ableton Link
- AudioBus Audio & MIDI support
- Use KRFT as a source with Inter-App Audio
- Import your own samples and export your recordings to other apps


*** iPhone 5, iPad 4, iPad Mini Retina or newer supported ***

Editors’ Notes

It is a new way of creating your own jam.


Insta-Buy 5-star App

Addictive. Endless musical fun, no hassles. Extensive series of short videos on the KRFT website get you started (and help you decide if KRFT is for you). Use the tweak-able synths and drums inside the app or let KRFT drive your gear and/or iOS musical instruments via endless possibilities for playing/tweaking/programming of midi loops, piano rolls etc. Further instantly tweak the midi with transformations, dials, morphs etc. Do all this while syncing with Ableton LINK and constraining scales for a like-buttah smooth experience. Download the groovebox-y scenes of other users online, or share your creations. Plus more and more... love this app. I don't write too many reviews but I had to leave something here for others to possibly get an outstanding app.


Great until Update

If you want to lose ALL of your ideas you took a long time on because you had NO idea it would crash after updating your phone, then this app is FOR YOU. Absolutely terrible. I emailed support and they simply said “it is not our fault you downloaded the update for your phone” are you serious right now? They try to claim it’s my wrong doing in downloading the “beta version” of the new update for your iPhone when I simply updated the newest version, as you should for any phone. I lost everything! Will not be using this app again. Plus there is no new sound banks and this app has been out for awhile now when you have to pay for the app in the first place! Aside from that, their customer support immediately jumps to blaming the consumer rather than offering anything for the inconvenience. I’m not the type to complain or expect anything in return, but this is just ridiculous. DO NOT PAY FOR THIS APP THEY WILL RIP YOU OFF.

Developer Response

In your email you stated you downloaded the iOS 11.1 beta from Apple. Apple state that your data is at risk if you use their beta software. It's your responsibility to back up your data if you are going to use beta software. We can't prevent bugs that Apple introduce in their software that impacts our software. In future I suggest only downloading the iOS updates when they out of beta status. Please change your 1 star review as it's totally unfair that you're tarnishing our product even though it wasn't our fault your data was lost.
