Touchable tablets may be all the rage at the CES trade show, showcase to consumer-friendly gadgetry. But quietly, developer Sensomusic has accomplished multi-touch control of an open-ended music system on standard-issue PCs and accessories. They’ve pointed the way to just what this mechanism could be.

The latest video isn’t terribly easy to see, but it realizes something that has been the dream of fans of the music control protocol OSC (OpenSoundControl). “Learn” functionality lets you touch a control, then assign that control to something in your music software. But because these functions have relied on MIDI, they’ve generally been a bit arbitrary – touch one thing at a time, get a number for that thing, then assign that number to a controller. It works well enough, provided you step through each control. OSC promises to do more, though: an arbitrary touch controller on, say, your iPhone (or anything else) can have a plain-English name. And you can see multiple parameters appear on the screen at once, so that a sensor or multi-touch pad could have all its messages pop up at the same time.

Finally, Usine does OSC Learn correctly, with messages that pop up with names and get connected to whatever you like. I still think there’s more potential here to be plumbed, but it’s a great step.

If you don’t follow why that’s cool, check out another mapping notion from last year – here using a touch panel to make any graphic playable. And at the end of this story, check out the clever multitouch gesture recognition they’ve added.

Again, all of this you can do with standard-issue hardware – Apple iOS hardware, if you like, controlling a PC, or non-Apple hardware displays with touch or Android devices and the like. (Unlike the Emulator we saw earlier today or the original Lemur device, it’s a software solution that works with your hardware of choice.) More to watch:

Sometimes things look interesting even before you can fully grasp just what they mean. Such is the case, I think, with what’s happening with SoundCloud’s on-the-go tools. Now, back in the beginning of this service, I predicted it’d become the Flickr of audio, and I wasn’t alone. But it’s becoming something else, something that really involves mobility.

The SoundCloud crew are out at South by Southwest, as good a gathering as any for the intersection of Web nerd culture with music and film. And they have something to show for it, too: they’re unveiling new Android and iOS mobile apps, among other updates – and location, with FourSquare.

Android phone owners certainly no longer need to feel like second-class citizens, with bug fixes, track commenting, and Twitter and Facebook sharing. You can also add widgets to your homescreen, a feature that iOS lacks. (I have to say, for all of iOS’ sophistication, the one thing Android does very well is make apps integrate with one another, and with data and the cloud.)

There are updates not only for Android, but iOS and desktop, too, detailed in a blog post geared for South by Southwest:
Create & Share (Even) More Easily

Both Android and iOS users get Foursquare interaction. That could mean … well, something. The ability to make recording a sound an event, to tie it to a place in the real world, is theoretically compelling. Exactly what you’d do with this data I think has a lot to do with the content itself. Might this be a way to tie, say, a live set to the venue at which it was played, or sound samples of an interactive art gallery installation, or an open mic night that has recordings and not just pictures? Possibly – although there’s nothing saying you really need a fancy tool to do those things, either.

With the Interactive portion out of the way, SoundCloud now gets unleashed on South by Southwest’s Music Festival, which has grown to an extent that it feels like all musical output has collided on one point. It’s a quantum singularity as much as a music festival. So we’ll see if SoundCloud does something interesting at those events – or if it’s just another eager Web name against the backdrop of a lot of booze-drenched music parties. And to me, it’s an open question how to use these tools to get more people in person, in the flesh, at live events, which I think for many musicians is the goal. (That is, you’d use SoundCloud to encourage people to get off their computers and go hear some live music!)

SoundCloud isn’t sitting around hoping you’ll figure it out, though; they have some tips:

Any of you in Austin or elsewhere in the musical world, if you do catch cool stuff happening with SoundCloud or other Internet-enabled audio, we’d love to hear about it.

Rather than dig through samples by abstract categories, you can use Freesound’s geotags to pull the exact ambience of certain parts of the world. It gives you the power to soak up the vibe of the beach at Playa del Medio without having to actually suffer through . . . erm . . . being at the beach. Okay, bad example. But while there’s the expected bias toward the U.S. and Europe, field recordings are slowly finding their way from other corners of the globe, too.

Aside from samples, it’s not hard to imagine geotags being used to help find musical collaborators near you . . . especially as latency increases over longer distances.

Sound maps: Field recordings in Forest Hills, Queens (outside Manhattan) are overlaid with an interactive map of the area. Upshot: drag with your mouse, and you can hear how the sound changes from one intersection to another, rather than just look at the usual visual representation.

Geo-tagging with a phone: This “participatory sound map” (shown below) lets you dial in the soundscape of different locations (here, again, NYC). Vocal representations get the emphasis here; I can see non-abstract applications, like different pizzerias explaining their handicraft, or finally a detailed map of how accents change in the five boroughs of New York. (And yes, locals can tell the difference between someone from downtown Brooklyn and Flatbush, let alone the Bronx and Queens. Now us outsiders can practice.)

Guided by Voices: Wireless headphones lead you through an installation . . . hmm, too bad this isn’t Halloween season, or this could’ve gotten a bit more macabre.

This should give some ammunition to those of you who like using field recordings in your music. Now remix your geo-tagged sound recordings, and you’ve got a musical application for GPS devices, Yahoo Maps, and cell phones . . . why not? And it’s a good reason to listen to where you are; that iPod battery was probably going to run out anyway.
