Yesterday, I talked about two complaints of music developers writing applications for the iPhone. These come from developers who are really iPhone fans, who just want to get their software released and (for many music devs) better categorized on Apple’s store. Pajamahouse Studios, maker of the new Sonorasaurus remix application, follow up with a more detailed explanation of their situation.

These are not rejections; at least rejections are generally accompanied with some sort of suggestion of what would need to be changed. They represent the dreaded iPhone developer “limbo,” in which an application is neither rejected nor approved. For Sonorasaurus, that’s been the state of affairs for over two months. As the developers explain, there seems to be nothing unusual about their app:

• Library access: It doesn’t access the iPhone/iPod music library. (no application is allowed to do that, which incidentally limits a lot of the DJ app possibilities of the device) Clarification: The status of the music API itself is unclear; some developers report just this sort of approval delay when trying to use it. [Source] Also, access to files inside the media library is not directly possible, which can be compared to the status of Android.
• File access: A separate http server is provided, with a parallel library, for users to store their own tracks – again, something found on numerous other approved applications. This doesn’t use the included library.
• Included music / music distribution: Five included songs are for testing only – something found in a number of other, similar applications that have been approved. The application is not an alternative to iTunes for distribution.
• Media decoding: Custom MP3 decoding technology – something not provided on the iPhone – was separately licensed. Clarification: This was not meant to imply that you can’t do MP3 decoding; the developers meant to make the point that they were not violating patents or licensing by using their own decoding, which presumably they did for the purposes of building a DJ app.

Of course, whatever the reason, we’ve seen in past applications suddenly approved after weeks or months, so who knows what will actually happen with this app.

While reading that, though, I also have to observe how significant these workarounds are. Without launching into an Android versus iPhone debate – believe me, there are many, many things to criticize about the Android as a platform, especially relative to music –  none of these is an issue on the Android. Forget platform wars or fanboys. Alternatives are good. I’d hope that we do have more than one approach to how to do this. These approaches should have to compete with one another, as they offer different tradeoffs and advantages.

If music is becoming an application, this kind of freedom is important.

A powerful DJ application for your iPhone or iPod touch may be a tantalizing prospect. But several would-be candidates aren’t available to you yet. Why? They’re languishing in Apple’s approval process, with no sign of whether they’ll be released or not.

For all the success of Apple’s App Store, some developers and users continue to express frustration at what they believe is a sluggish, unpredictable approval process, restrictive Apple policies, and Apple’s complete control over distribution and categorization. That now leads to two complaints from music developers. A number of music developers want more delineation from Apple’s categories, so that the flood of general music apps don’t drown out powerful, creative tools. Meanwhile, developers of DJ applications claim that Apple is discriminating against DJ apps, which they say has led to delays without explanation.

“Open” development is relative, without question. Game system makers require developers to prove to them why they should be “allowed” to create titles, leading to a tightly-controlled stream of approved titles. But the success of Apple’s relatively open development model has prompted many software creators to hunger for greater freedom. I’ve increasingly heard people enthusiastic about the more flexible distribution model on Google’s Android (and other Linux) platforms, which allow users to install apps they want. I even moderated a mobile music platform panel at the CMJ music conference at which a Verizon representative, no less, talked about wanting to be more open to applications. The benchmark was Apple, for being perceived as overly restrictive.

iPhone/iPod touch developers, however, aren’t simply ranting against Apple. They’re complaining because they’re enthusiastic about the App Store. They want changes from Apple and believe there’s potential to get what they want. That said, I think they also illustrate potential for rivals like Google to outdo Apple – assuming those rivals invest more time and effort into courting these kind of applications.

Is Apple Blocking DJ Apps?

First, some developers believe that Apple is intentionally blocking DJ applications from being approved. Whether intentional or not, a number of potentially ground-breaking applications are unavailable after a significant delay. Kasabian Kasabianmeister writes:

Rounding up my catch-up-on-iPod/iPhone-stories, here’s one from the developer perspective – one that could face music creation developers on the entire platform.

The Apple iTunes App Store now faces the risk of becoming a victim of its own success. Music applications could be a big part of that, without some adjustments on Apple’s part. The problem is this: incoming music “fan” apps could flood out the music production apps that had enriched the mobile software platform since its debut. I think the need could be really urgent. Consider that part of the appeal of Apple’s mobile platform – yes, even in stark contrast to the Google Android on which I’ve been developing myself – is its spectacular real-time audio tools. Combine that with a disproportionately large number of Mac-using musicians, lots of ingenious apps build on Apple’s Core Audio platform, and we’ve seen a mobile platform with an extraordinary number of tools for music creation.

The problem now is that that unique set of powerful apps could get overwhelmed by essentially unrelated “music” apps. A developer who has asked to remain anonymous is already campaigning for a change. He does a good job of explaining the issue, and what might need to happen to fix it. If you’re a developer, you can add your support and feedback to the idea.
