What's New in Konstrukt

1.2

November 9, 2026

Konstrukt 1.2 — the biggest update yet. • Host AUv3 instruments, effects and MIDI effects inside the patch — and make sound without one: Synth, Wavetable, Drums, MegaSaw, Sampler and Slicer, with Drive, Filter, Delay, Reverb, Compressor, EQ, Chorus and Phaser, each with its own panel • The Rack page — the audio side on one page: a strip per instrument with inserts, sends, sidechain, MIDI Learn, master inserts and scenes with fades; External Instrument channels for hardware • Audio in, master and stem recording, Ableton Link, MIDI clock in and out, tap tempo, count-in, multi-output routing • New sequencers — the Drum Grid (a whole kit in one lane), the Beat Map (an X/Y pad that blends drum patterns), the Metropolis-style Stage Seq, and a Chord Seq with rhythm, strum and voicing layers; patterns up to four bars, eight banks per lane, record into patterns, ratchets, custom scales, a patch key every lane follows • Components — fold a cluster of nodes and its surface cards into one card with real ports; save it, drop it into any patch, edit it inside (graph editor) • Players — tap the star on a lane and it writes a Drum, Drum Grid, Step, Analog or Chord Seq pattern from a style and a Complexity slider • An arp on every keyboard, a MIDI FX slot on every track, New Patch templates and many more improvements across the board

Great concept... when it works.

List of weird/broken things after 10h of making patches:

(1) Can't rename modules in the Graph Editor when my iPad is in landscape. Landscape only. However, when modules are renamed, they do not always show up as their new name in the Surface Builder. Pretty rough, because Graphs get complicated quickly, and it's hard to tell what things are from their default name.

(2) Snap module does not work, as far as I can tell. You cannot quantize notes timing-wise to your rhythm. Sucks if you're doing generative MIDI, which is the main reason to buy this app over KB-1 IMO.

(3) CC Math > Invert does not work. Sidechaining MIDI (eg muting a hi-hat when a kick hits) must be done some other way that I haven't figured out or is impossible.

(4) None of the "-scope" views display Node Parameter values, despite having controls to be bound to those values. Obviously I want to see how a value is changing over time if I'm modulating it -- but I can't.

(5) The Bounce Generator does not have physics between the balls or even different starting points when you add more balls. Sounds silly, but it means that a 4-ball generator just plays the same rhythm, transposed slightly differently. This seems incorrect (see any other physics-based MIDI tool), bordering on false advertising.

I have a dozen other friction points -- try setting a specific Note output with the default Slider or Knob, good luck! -- but most of them boil down to differing UI sensibility.

I sent a support email to the address on their website ("we read every message!") but have not received a response after three days. You might be on your own if you buy this one.

Given that $15 + $15 is Premium-Tier in the iOS music scene, I'd hold off on this one. Drambo, Imaginando LK, and Prism Sequencer are much more mature and will do this kinda thing without the admittedly-awesome Graph Editor + Surface Builder workflow. Still, I'd love to see MidiRack live up to its concept.

It's just not there, not yet.

I really enjoy this app but…

I really need dotted and triplet notes for all note divisions. It’s something I request for all apps but midi including dotted and triplet notes is perhaps more important to me. Looking forward to see what happens with this app going forward. It reminds me a little bit like working in the note grid for bitwig.

Great creative and deep tool.

I bought it soon after it was released and loved the deep modular routing possibilities with an intuitive interface. I was concerned when the touch response on the sequencer lanes wasn’t always working . Kai responded instantly to my questions and fixed it days later (works perfect now!) Also, I asked about file management and preset folders and he added that stuff now with the latest update. What more could you ask for from a developer.

If you make music with an iPad you need this

Thank you Kai for putting together such a great piece of work. Everything works flawlessly so far.

hot out of the fryer, and this meal was ready to serve. ambitious for any music dev—but he nailed it. I definitely recommend the node editor IAP to reap the maximum benefits of the app; moreover, the upgrade sits humbly out of your way, never pressuring a purchase.

for the record, a very thoughtfully executed 'cheatsheet' seamlessly loads within the app when needed for nodular reference, leaving your creativity uninterrupted. incredibly lightweight on DSP, too. thus far weighs in on my mind as one of the important iOS releases this year.

I had been wondering what would follow Mr. LoFi... but was in no way anticipating an entire workflow reconfiguration. you've outdone yourself, Kai! thank you for this incredible release!
