It’s hard to believe it’s been 12 years since the introduction of Korg’s influential KAOSS Pad. Now, Dutch developer Victor Bergen Henegouwen gives a nod to the Korg hardware with a new iPad app. And Victor writes CDM to let us know it’s hit the iTunes Store now.

Like the original KAOSS Pad, you can use any instrument or source, in a way that could appeal to DJs, musicians, and producers alike, and control effects with a sweep of your finger. But in the context of an iPad, LiveFX adds multi-touch control, free mixing of parameters, and the ability for the first time to add other apps. In fact, LiveFX may be the first app to be built from the ground up around Audiobus, the platform that allows iOS apps to be connected with one another.

Also, in a big departure from most iOS apps, this one will add effects directly to sounds in your iTunes Library. That could make this part of a DJ rig – or allow a simple performance instrument in which backing tracks or other source sounds are loaded into iTunes, and LiveFX does the effects magic.

True KAOSS lovers, of course, will get an iPad and a hardware KAOSS. (Korg’s own iKaossilator is their own KAOSS-on-iOS entry, but the company has yet to produce a true effects app. No complaints here, as they’ve done some amazing other apps like the iPolySix.)

Feature highlights:

  • Use any audio source – including the iOS iTunes player, or, externally, vocals and instruments and DJ sets and the like.
  • Audiobus support for use with any audio app.
  • Combination effects, either mapping up to four to a single finger or multi-touch for dynamic effects. (I always loved the KAOSS Quad’s combination effects; on iOS, you get more flexibility and multi-touch options.)
  • Existing presets, custom patch saves.
  • Lock button (aka “hold”, as on hardware).
  • Vinyl Break, Ducking Compressor.
  • Auto BPM detection, Tap Tempo.

As a KAOSS Quad owner, I can certainly see some common features in the effects design, combination effects, and color X/Y pad. I don’t think I’m dumping my Quad any time soon – I love the ability to have hardware. But for performing with (or just having fun with) iOS apps, LiveFX makes the iPad – and Audiobus – a whole lot more interesting. We should have an Audiobus test with various apps soon, now that I’ve upgraded from my anemic iPad 1 to a (steeply-discounted) iPad 3. In the meantime, enjoy some videos:

LiveFX is actually free in the App Store; a full version is a US$8.99 in-app purchase. In other words, you’re getting a free version as a demo, and then can choose to spend money if you like it – possibly a good system; let us know what you think of it when you try it.

    sadly ios6 is required

    So is the free download still it’s full capability? It says “use live without interruption” as a full version spec, but I haven’t seen what that means yet. I like it but I don’t love it..

      oh, never mind I see…

    Perhaps a stupid question, but is there a way to use an iPad (I have a Mini) as an external FX device with a mixer? Can I send a stereo signal in and get stereo out somehow? This looks like great fun, but I work as much with hardware as I do with software and would like to route it through my mixer.

      Almost any standard Audio HID USB device via the Camera Connector Kit. I use a Mobile-Pre. Roland UA-3 has S/PDIF as well as analog. etc etc.

      Can you elaborate on this some more? I took this question to the Apple Store and none of the staff could help. I’m looking to use the iPad and app as an external effects processor from a DJ mixer.

    This looks brilliant. I have an old KP3 that is sadly gathering dust …mostly because of ergonomics. (Studio is cramped, running wires is inconvenient.) BUT my ioDock is sitting front and center in my set-up soooo maybe I CAN integrate something like the KP3 back again! There’s already a bunch of naysayers dinging it for the in app purchase model and price. People expect stuff for free these days. COME ON. It’s a KAOS QUAD for less than $10 bucks…! I paid THIRTY times that for a KAOS pad 3 five or six years ago. Perspective missing methinks.

    Rather just do this in Logic with a touchscreen with vector objects like this

    Getting the audio out to an ipad is a pain.

    In your blog have mentioned standardized features, and it has provided the good knowledge to use this type of apps.

    iPhone has become rather worthless for mobile music as everything is nowadays iPad only
