You’re now approved to DJ with your iPhone. Or at least the app is. I’m not sure if I can take credit for getting Apple’s attention, but Apple has approved the TouchDJ application from Amidio. That’s big news, partly because developer Amidio has consistently been at the forefront of musical development on the platform, including their Noise.io synth and wild hexagonal JR Hexatone Pro.

This also is a big blog to the theory that Apple is intentionally blocking DJ apps — and a big boon to the theory that the App Store is just plain clogged, even if it may be disproportionately affecting more sophisticated applications.

Features in the release:

• “Visual mixing,” with a clever interface that uses overlays atop side-by-side waveform views
• Pre-listening using a special left/right adapter
• Faux vinyl and spin effects
• Real-time scratching, looping, positioning, EQ, effects, re-pitching
• Onboard sampler with 3 WAV sample slots, recording from the mic
• Uses a separate MP3 library with companion apps, since it isn’t possible to DJ from the library you sync from iTunes

Now, to me, that last point is a fairly significant one. You have to load tracks you wish to DJ separately, in MP3/M4A format. And I’m sure that this will start various debates about whether you’d want to DJ on your iPhone in the first place. But don’t look at me — I just work here. I’d be remiss if I started out the week talking about apps stuck in iPhone limbo, only to ignore them immediately becoming available. And I will say, Amidio is one of the smartest mobile music developers out there, so it’s worth checking out the range of what they’re doing.

Whether petitions and news stories did help this app to get to the top of the queue or not, I have no idea. I think maybe I’ll start running screaming headlines with things I want in them, if only for good luck.

Tomorrow on CDM: “You Know What Annoys Me? The Fact That We Don’t Have Unicorns. Magic Unicorns. Who Speak OSC.”

Dream Theater keyboardist Jordan Rudess and noise.io developer Amidio have made a crazy-looking hexagonal sequencer for the iPhone. It comes with plenty of samples and factory sessions if you just want to play around, but I imagine the greatest draw for CDM readers is that it allows exporting your own files via a WiFi server application.

(Ahem… cough… Google Android and others don’t require any special app just to get files onto your mobile device. Sorry, something got stuck in my throat. Cough… ahem… can we have a real, live audio system in Android now, please? Whoops, throat thing happened again.)

This application also works with Beatmaker, so you now have a pretty nice studio of mobile apps on the iPhone and iPod touch. If your arms have been cramped whipping out your laptop on the Chinatown bus to Boston (now with 6″ of legroom), this could be a huge help.

More features:

• Stutter, chorus, and bit-distortion effects
• Seamless loop creation you can use with Beatmaker or your own favorite audio production tool
• Cell randomization

JR Hexatone Pro is US$9.99.
