◆ 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 ***

I love this app but there are some problems

I absolutely love this app and use it to make music all the time, however, when ever I put the quantization on anything less than 1/38 the keys stick and continue making their sound. This can be very annoying when trying to make a song, if you were to fix this problem I would probably give five stars. One more thing I want is for you to add an actual piano or keyboard screen. The pads work okay but I think an actual piano would allow people to create much better music. Thank you.

Essential iOS production tool

I don’t even use the included sound engine that much and this is still one of my top three iOS music production apps. Krft is my main sequencer/arranger on the iPad. I’ve had sync issues with AUM but have found that changing sample rate to 48k in AUM causes perfect long term sync. I hope a fix is possible to improve 441k sample rate sync but until then it’s a minor issue I can work with.
The two main reasons krft shines over other midi sequencers for me:
The piano roll/step sequencer layout is just perfect. It’s not fiddly, there aren’t excessive menus and options, and most importantly there’s no zooming in and out and trying to input notes into tiny squares. It’s better than any other iOS sequencer in this regard.
Second is the key pads for playing notes. They’re so elegantly and simply laid out. I swear iOS devs love making their apps ugly and unnecessarily unique. This is exactly how they should be laid out.
My only complaint is that if left unused it often freezes in the background and needs to be restarted. And midi note velocity going to 127 would be nice as well.
Krft devs, please don’t abandon this app, it along with AUM is the center of my iOS production setup. You’ve created something great.

It's a game changer in many ways. Musical, accessible, usable even on a phone form factor, plays well with other apps and even hardware. The one missing item standing in the way of five glorious stars is a way to share surfaces *as files* to collaborators. Network feature is nice but global public sharing shouldn't be the only way to share or archive a project.
