MSAFluid for processing (Controlled by iPhone) from Memo Akten on Vimeo.

TUIO is a simple but powerful emerging protocol for multitouch control for live music and visuals, as used on the powerful live tangible synth reacTable. Apparently no one told Apple, however. While the App Store rubber-stamps useless toys like fake cigarette lighter flames, they bizarrely rejected a powerful application by a leading digital artist that would enable standardized TUIO control – for free. (More back story below; see an example in action above.)

As a blogger, my reaction is usually to whine and pontificate, for better or worse. The engineering approach would be to find some hack away the problem. That’s what Andrew Turley did with the TUIO protocol. So, Apple won’t allow an app that does the trick? Why not go back to what developers did before the SDK, and just use the iPhone browser?

As Andrew explains it:

After reading the story I started thinking about seeing how far one could push Safari as an application platform, using web apps to get around Apple’s tight control of the app store. Since you would be connecting to another computer anyway to use an OSC application, why not just have the app be a web app running on a web server somewhere on the local network? The web server can then take care of things like sending out OSC messages or playing music or doing whatever it is people want to do.

To that end I created a little system that implements the TUIO protocol. You use an iPhone to run a web app, which in turn talks to the web server, which in turn sends OSC messages.

There’s been some confusion from our readers and existing beta testers of SoundCloud (see their forums / login required) about what you can get with a free account on the service.

Co-founder Eric Wahlforss answers some of these concerns in comments. With a free account, you will be able to:

• Send/upload up to five tracks a month, of any length/size
• You can upload as many tracks as you like, but only your ten most recent tracks will be visible to others (unless you delete tracks). No tracks are deleted – you can upgrade/downgrade at will.
• You get a DropBox, and the most recent five tracks dropped will appear (again, if you delete tracks as you listen to them, you’ll see more)
• Make contact lists with up to 20 contacts
• See basic stats

So, the free account does look reasonably usable for light use. That said, they are clearly trying to push people to pro accounts, which start at EUR9 / mo. (Even separate USD pricing would help, I think … even though the dollar has recovered a bit in recent weeks, unlike our – ahem – stock exchange.) Eric does promise more is coming in those pro accounts to entice you, if you feel the value proposition isn’t there yet.

SoundCloud: The Tour from SoundCloud on Vimeo.

SoundCloud, an online sharing community for sound and music, is now hours from public launch. I’ve been playing around with a closed beta for several months, and have to say, I’ve been really impressed. SoundCloud isn’t the first attempt to provide places to share music files with others, but previous attempts have been lackluster when it comes to easy sharing, features necessary to make music listening more enjoyable, and upload capacity. Most importantly, none has accomplished the community “stickiness” that has been the cornerstone of successful media services like Flickr, Vimeo, and YouTube. In fact, there’s been so much of a noise-to-signal problem with the Web space, I expect a lot of you have simply tuned out new Web services. There are some good reasons to pay attention to SoundCloud, though:

• Singing telegram, anyone? Music on SoundCloud acts more like a messaging service. Tracks from people you’re following appear in an inbox for you to sort through. You can even create a DropBox for other people, so this could be huge for people running labels or live events. (That’s especially welcome now that a lot of people have given up on individually clicking myspace links to hear what someone sounds like.)
• Easier uploads and sharing: Getting files on the service in your favorite format, with whatever length you want, is a whole lot easier than on competing services.
• Smart player interaction: Services like this now live and die on their embeddable player. SoundCloud’s is really clever and attractive. Download links are everywhere. Also, SoundCloud attacks the biggest problem with music – it’s invisible. There’s a waveform view, and people can comment on specific points in your music. That feature has been annoying in a lot of video players, but here comments appear only if you want them to, and I’ve found them really helpful in getting feedback. (See my example track below, for instance.)
• Open API: A full API means you can built interesting apps atop SoundCloud. Check out the lovely Radioclouds by Matas Petrikas for an example of how interesting this can be; source code is available.

SoundCloud, indeed, seems to have all the kinds of features that made Flickr stand out from a crowd of photo services. Labels are already onboard, too: Compost, BPitch Control, and Goldie are already making it part of their workflow, says SoundCloud.
