"BEST HOUSE TECH GLITCH D&B APP in years!" "Fantastic app" K Machine is a new kind of audio visual instrument, allowing the creation of sound & touch responsive, dynamic, and vibrant animations. Designed for for musicians, shaders enthusiasts, VJs, and animation lovers in search of a live oriented, open, audiovisual instrument, K Machine combines a powerful audio sample sequencer and an original vertex shader sequencer based on a unique 'automatic transition interpolation' engine. ▶ A multifunctional tool The K Machine can be used in different ways: • As a VJing tool, using an audio input through mic or any other Audiobus compatible App. • As a sound creation tool, with the default empty shader so you won't be distracted by any visual animation. • Or in its full potential for true audiovisual composition. ▶ Import your sounds • K Machine accepts WAV and AIFF formats, 16 bits, 44100 Hz • Import from iTunes File sharing, Audioshare, Audiopaste or "Open in..." from any app with Export functionality. ▶ Import your visuals • The initial version of K Machine comes with more than 30 default vertex shaders, and 4 commented shader examples. • No limitation ! Import your own visuals, with the "Open in.." feature, use any external code editor App with Export functionality to create your own vertex shaders files. • Shaders format is 100% compatible with shaders from vertexshaderart.com • A simple line of code allows the creation of up to 8 parameter controllers for each vertex shader. ▶ A flexible tool • Each loop can have its own BPM. • Each loop can have its own number of beats. • Events can be splitted in 1/3, 1/5 1/7 or 1/11 ! ▶ Capture videos on the fly • Simple click on the 'video capture' button starts live video recording of your ongoing session with zero drop in performance. • Resulting video is automatically recorded in your photo album and can be shared on Facebook, EveryPlay, Youtube... ▶ Project on second screen with invisible UI Connect your device with HDMI or VGA adapter to display only the visual part of the ongoing animation. Perfect for live session ! ▶ Universal app Buy once and use on your IPad and Iphone devices. ▶ Use with other apps • Ableton link Ableton link: synchronise with any Ableton link app. • Audiobus 3.0.3 • Audiobus Remote: control K Machine from another device. • Audioshare: import edit your own samples with Audioshare. • Audiopaste and Audiostore: import sample with Audiopaste and/or browse an amazing sample collection through the Audiostore. ---------------------------------- See a new online video demo for v 2.0 here: https://vimeo.com/215816844 https://www.youtube.com/channel/ Full documentation : http://kolargon.art/KMachineV2Doc/KMachineV2Documentation.html ------------------------------------------- Disclaimer: K Machine gives it's full potential with openGL ES 3 capable devices.

Such a shame ### 5/5 — Please update! Can’t open the app since I purchased it *2024-06-10* Can you please update so it doesn’t crash each time when the app is launched Thank you ### 5/5 — Can’t open the app since I purchased it *2024-05-17* Can you please update so it doesn’t crash each time when the app is launched Thank you ### 3/5 — Can’t open the app since I purchased it *2024-02-18* Can you please update so it doesn’t crash each time when the app is launched Thank you ### 1/5 — Update or compensate *2023-10-10* Can you please update, I don’t even know what this app does, since I bought it I haven’t been able able to open the app, it crashes every time I try to open it ### 5/5 — Great little radical visual program with mega potential *2023-05-04* Having just sold my critter and guitari Eyesy I am finding this app wayyy more awesome. I’ve been finding some difficulty in getting some visuals with iPhones but I’ve got this rigged up to a vga iPhone adapter, then a vga to composite converter and into a waaaavepool video delay and feedback module for added coolness. Unfortunately kmachine will crash whilst I’m using it on an iPhone 12 Pro plugged into the vga adapter (it doesn’t crash when not plugged in) so I’m using an older iPhone 6 which seems to work. I still have to try it with Ableton link but I may not need to if I can get audio reactivity another way. It works anyway!!!! Pretty cool projected onto the wall or crt. Still experimenting and I’ve got an hdmi adapter coming as well so will need another converter for that to plug into the waaaavepool or just see if it will work with the iPhone 12 also actually thinking of getting an iPad just for this app in my home studio so I’ve got the bigger playground. Just need to get more shaders in there as well which I’ll go and see about importing. There’s actually nothing like this out there. Even the likes of Hyperspektiv which is a cool visual app will not go into a second screen mode so there is the logos and recording toggles projected which you don’t want. Hyperstream works but it’s visual augmentation as opposed to cool graphics. I’m glad because there isn’t a great deal of VJ programs for windows on my desktop either. It took so long to find a setup that works and this app has made me very happy today, thank you! ### 2/5 — Not good *2021-08-19* Early days and will give it another go but first impressions are not good. At that price im possibly keen to get a refund tbh ### 1/5 — Why is this so prehistoric? Adding samples is from 2010! *2020-10-12* Please admit how difficult it is to add your own sounds. That will at least make us all feel better. How about a free update this decade. Ty. **Developer response:** @RobBerzon, Well, yes it can be a bit tedious on this version, no problem to admit ;) but look, I'm am working hard on the next release, massive update. It takes time, but worth it. Plus you will get the free update ;) ### 1/5 — App won’t open *2020-01-06* Paid good money for this app and it won’t even open/launch. Tried deleting and reinstalling and still had the same issue. Happy to reconsider and rewrite my review if this can get fixed. **Developer response:** Hi max81898, Ok, sure, happy to investigate the problem right now, though, a few infos would be needed: what device and what IOS version ? any other app running ? if possible could you contact on service email: kolargon.art@gmail.com ( always the best way to have quick answer/bug report, and always interested by any bug report!). Thanks for your interest and feedback ! best ### 1/5 — Trash - waste of money *2019-12-19* Clearly a lot of time and effort went into this app - lots of functionality and features. I had high hopes. Such a shame it’s fundamentally unusable - hire a UI designer you clown, it’s 2019. This app is abysmal. My mother could design a better layout. **Developer response:** Hi 507 502 130, sorry to hear that the current layout triggered such a distress to you. A totally new version (UI and much more) is in preparation, hopefully much more user friendly. However I sincerely invite you to ask refund from the Apple Store, the process is very straight forward (but do not hesitate to contact by email if you need help with it). best ## Frequently asked questions about K Machine audio visual engine ### What is K Machine used for?
