Your pocket is bulging with power.

Wait… okay, that sounded really wrong.

Anyway, the mobile software revolution continues. There’s so much stuff out there that it can actually be hard to track. Here’s a round-up to help you navigate everything that’s going on this week.

And even if you can’t stand another word about the iPhone, consider this: the explosion of iPhone software, more than just a fad, illustrates what happens when you give developers tools to make multimedia capabilities easier, then provide a distribution outlet. I don’t love everything about the iTunes approach, but those are lessons that could easily be learned in desktop and mobile development alike. The iPhone platform, if nothing else, is surprisingly uncompromising in the sound and visual interaction departments, especially for a mobile platform. And even desktop platforms could benefit from this kind of distribution mechanism (see also: Steam for games).

Also, we do have some of the first signs that the iPhone won’t be alone for long – new functionality on Google’s Android could take that platform in new directions. See my next story, Android/Linux/open source fans.

Disclaimer: don’t worry. I’m not giving up on desktop apps. Relax. In fact, even now as I look across these applications, while there are lots of cool ideas, it’s still clear this is a nascent area. The experience is nowhere near as rich as you get on the desktop. But it’s nonetheless worth exploring some of the ideas before we return to our (more powerful) desktop applications for music.

Interested in experimenting with MIDI, minus the wires? Why not try a DIY hack yourself? Limor Fried aka Lady Ada of Adafruit Industries has posted a detailed tutorial on transmitting MIDI over the inexpensive and relatively friendly XBee wireless module.

It’s a bit of a hack – you force the XBee to communicate at MIDI baud rate, and on Windows, at least, you have to fool the OS into using MIDI’s non-standard baud rate for serial communications. But it seems to work. That’s where you come in: Limor’s got some folks testing this, but we could use some additional real-world tests and a “port” of the instructions to Mac OS and Linux. (I’ll be testing, too, once I get my hands on some spare XBees.)

Wonderful things happen when you invite lovers of noise together in a room. Musicians and non-musicians, electronics geeks and first-timers, folks pick up a soldering iron — often for the first time — and cause utter mayhem. So we again had a fantastic time at Handmade Music last month. I’ve just gotten the photos in, so decided to share.

We’re looking for folks to bring stuff to Handmade Music on 4/16 – see the bottom of the article and give us a shout if you have software or hardware creations to share. They don’t even have to work, entirely – this is the place to find people to help give advice, so we like even partly-functioning inventions.

Even if you live far, far from Brooklyn (like back in Old Amsterdam), the featured March projects are within reach:

• Loud Objects Noise Toy was the star of the evening. Lesley Flanigan and Tristan Perich of Loud Objects — superstar composers and sound artists themselves — were onhand as patient teachers and guides in the ways of Noise.
• glitchDS on PC and Mac: The DS homebrew creator Bret Truchan delighted with not only his mobile gaming creations, but a netbook running a new PC cellular automaton MIDI sequencer, ported to Processing. More on that soon. (See the image captured by Make Magazine’s Collin Cunningham.)
• Pulsantes I got Jaime Munarriz’ strange Processing + Pd pulsating rhythmic toys working on a PC – thanks, Jaime, for the virtual contribution!
• jReality Peter Brinkmann demonstrated the sonic capabilities of audiovisual virtual reality framework jReality. Intense stuff – you don’t even need to use Cartesian coordinates. Elliptical, baby!
• Networked Objects: Eric Beug brought by his DIY wireless synth modules and an iPhone for control. This progress is under development, so I hope it makes a repeat visit.

By the way, in case you wondered what happens when a bunch of people play all their newly-built Noise Toys at once? It sounds something like … this (and sorry, my digicam mic was entirely incapable of capturing the resulting sonic chaos):

Your feet are your two most valuable, underused extremities for music. Your hands are busy, but your feet can trigger transport, recording, looping, different instruments … you get the idea. All you need is a perfect controller.

AlexMC on the Ableton forum liked our $10 DIY footcontroller for Ableton Live, as engineered by Mike Una. But he thought he could do better. So he takes the design from ghetto-fabulous in Mike’s previous iteration to dead-sexy.

The starting point is again a USB QWERTY keyboard, but now AlexMC takes the brains out (the PCB that handles input from keys and communication with the PC). Alex has copiously detailed, step-by-step instructions for soldering and assembly, along with circuit diagrams and specs for the case. There’s even still an LED attachment.

And because it all sends keystrokes, this is hugely useful in something like Ableton Live:

I now have 21 buttons, 20 of which send up to 40 unique outputs depending on the status of the BANK switch…

The main intended use will be to control REC, PLAY and STOP for each of 12 separate tracks in Live, leaving three switches for:
- CAPS (i.e. BANK)
- Stop/fade out all tracks
- Tap tempo/engage metronome

Of course I can dynamically re-assign any function during a Live session by activating the Key Mapping function – without stopping the music.

Sure beats a Boss looping pedal, doesn’t it?

Mixed Up – Beat Blender and Mixmaster 1200 from Matti Niinimäki on Vimeo.

Matti Niinimäki is back DJing with flea market, broken appliances as physical interfaces – and the whole project is getting better and better. We saw an early prototype of the Beat Blender, a re-purposed Osterizer with fake fuzzy fruit that stand in for loops. Now, Matt has added a handheld mixer for scratching.

The Mixmaster 1200 is a wireless scratching device for the turntablist who prefers to deliver his/her scratches like a 5 star chef. As you can see, the Mixmaster does not have any beaters attached to it. This is because it has small laser powered plasma emitter beaters that actually heat up the airwaves around the device itself producing the unique sounding aural explosions.

I recently got to see a Numark NS7 in the flesh, the controller that company hopes will be the last word in DJing. It’s got nothing on this.

I’ve got to hook something up to my Breville… maybe temperature sensors.

Matt may have beat you to this idea, but I guarantee, if you’ve been thinking about alternative controllers, you will never see a flea market in the same way again.
