iPhone Day: Free Frameworks Make Thumping Apps, Mobile or Otherwise

Part of the beauty of the iPhone from its launch date was the notion of a Mac you could fit in the palm of your hand. That makes it ironic that, for so many developers, mobile platforms in general have turned into a way to fragment software, to make it run fewer places instead of more. There’s something to be said for designing to a specific mobile device, but on the other hand, how many developers would want to restrict where their creations run? And particularly in music, isn’t the appeal of mobile creation the ability to have your tools work in more places? Maybe targeting just one gadget is the right choice for a given tool, but it shouldn’t be the only choice.

On the iPhone, the application Thump has plenty in common with a range of mobile music making tools. It’s simple but fun, a groove box with sequencing, subtractive synths, drums, and a set of basic effects, plus the ability to load your own samples and export songs.

Thump also demonstrates how simplifying sonic capabilities can produce musically-beautiful results, by focusing on the essentials and creating something with personality. Here’s a track by its creator showing off its sounds:

Well worth checking out the app on your platform of choice:

What might not be immediately apparent is that under the hood, Thump makes use of the open source environment openFrameworks. As a result, the same code runs on iPhone, Mac, and Windows, as well as Linux. (It’s not distributed for Linux, but it could be. Hint, hint.) Creator Marek Bereza gives back, too – he ported the openFrameworks audio library to the iPhone, where it’s available to anyone.

Updated Marek notes in comments just what this means. The video below is, essentially, the same app. In place of the iPod screen, he has used a massive lattice of physical controls. A separate installation at the same show used a large touchscreen and simplified interface. And this really demonstrates what cross-platform means. Guy Kawasaki in the 80s mocked “ports” as a cheap wine. The idea is not to simply dump your code on a different platform and hope for the best – in fact, in this case, the changes from one platform to another were radical. The key is maximizing what’s essential, what really is not specific to a single device.

If you’re interested in creating your own projects, oF has an elegant syntax based on Processing, but adapted to C/C++ coding paradigms and libraries.

iPhone Day: LaDiDa’s Reverse Karaoke Composes Accompaniment to Singing

LaDiDa Demo from khush on Vimeo.

There’s no question iPhone/iPod touch development – really, just clever mobile development – has gotten a bit overhyped lately. But that’s all the more reason to do a round-up of genuinely interesting stories, real innovation happening on the platform. So, I’m clearing out my inbox with some of the more creative tools appearing recently on Apple’s mobile gadgets. There’s no better way to kick off today’s festivities than with this unusual “reverse karaoke” creation.

Sure, people may think they’re tone-deaf. But even the layperson has extraordinary powers of musical perception. So how could you train your iPhone to perceive and respond to music? That’s the question asked by LaDiDa for iPhone, the first of a new line of “intelligent” music applications for mobile devices. A “reverse karaoke” tool, the idea is to listen to singing and fake accompaniment, rather than having you sing along to canned backing tracks. Nothing is pre-programmed; everything is generated on the fly on the device.

It’ll even make up a Bollywood accompaniment to your singing:

Of course, to me, it’s interesting not only what the iPhone is able to musically, but also what these algorithms are unable to make sound musical. Both reveal a whole lot about how we hear and conceptualize music. I think the team deserves real credit for making this fun, though, and on constrained hardware.

The app’s creator Khush follows in the footsteps of Smule in that it takes hard-core academic music research and uses mobile devices as a vessel for getting that tech in the hands (literally) of the general public. (See my interview with Smule founder and ChucK originator Dr. Ge Wang.)

Parag Chordia, developed at professor at the Georgia Institute of Technology and the gentleman you see in the video, spoke to CDM about what’s happening behind the scenes. He tells us about how this application was developed, and how the intelligent algorithms work (or at least try to work, as music analysis and auto-accompaniment remain at early stages).

First, an explanation of the app.

Image-Line Deckadance: The DJ App/Plug-in To End All DJ Apps ?

The creators of Fruity Loops aka FL Studio (Image Line software) have just announced a new DJ application called DeckaDance, and this thing looks like the answers to our prayers. We here at CDM love applications that don’t tie you into a specific controller/hardware/control vinyl solution. DeckaDance seems to have everything we’ve ever wanted in a DJ application, and not only does it support several different types of control vinyl, it actually has a learn mode to adapt itself to new types! Add the fact that it’s a VST host capable of hosting both effects AND instruments, and is capable of operating as a VST plugin as well, and I think we have something that will truly change the face of DJing (unlike some other recent products). Here’s a run-down of some of the more notable features:

  1. Works as standalone or VSTi plugin
  2. Hosts VSTi soft synths & FX in 8 slots
  3. 8-slot sampler that samples from the decks
  4. 6 inputs & 12 outputs
  5. Supports Final Scratch, Serato Scratch, MixVibes and (our favorite) Ms Pinky vinyl
  6. Capable of learning new vinyl control systems
  7. Auto-sync
