Reware your PDA from Hans-Christoph Steiner on Vimeo.

Give a hoot – don’t pollute with your old mobile gear. Make musical creations with it instead, powered by Linux.

Sure, there are wonderful things happening with mobile music applications on platforms like the shiny, new iPhone. But remember how technology was supposed to democratize access? Lots of us don’t have the money for a new iPhone or iPod. And how many of us have outdated Pocket PCs and Palms collecting dust? How many of these highly toxic devices get thrown away?

Linux to the rescue.

One of the biggest hits of my talk at the OFFF Festival in Lisbon, Portugal was the mention of the Reware, a project by Hans-Christopher Steiner, who is doing research at New York’s Eyebeam. He has literally a box full of old PDAs – the kind a lot of people would give away at this point – which he has rescued in order to reuse as development platforms and musical devices.

There’s something just stunning about watching an old Pocket PC transformed into an interesting musical device. It’s like the feeling you get when you save a puppy with the help of a rescue / adoption agency, and instead of being put down, Buster turns out to be an agility champion. (Sorry. I really love dogs.)

Reware Project at Eyebeam

For a sample project, here you can dual-boot Linux on an old Palm:

Once you’ve done that, you can run your own creations and even Pd patches on your mobile. Even old iPods can work.

Pd Music Patching on PDAs

It’s a little trickier to recycle older embedded devices than it is desktop computers: for one thing, many of these devices lack floating-point calculation capability. (The FPU on the iPhone is one of the things that makes it so nice.) For fans of the multimedia environment Pd (Pure Data), the variant PDa (“Puredata anywhere”) is the solution. It rewrites signal processing as fixed point (integer) processing. It’s nowhere near as fast as a floating point-native Pd, and there are some other caveats, but there’s still a whole lot you can do with it. This is also good news for the currently-shipping Google Android handset, the HTC G1, which also lacks an FPU.

PDa 

Gunter Geiger is responsible for PDa, with help from lots of other folks. Now Hans is packaging all this stuff together to make it easier to run.

See it in Person; More Soon!

If you’re in the New York area, next week Hans is coming to Handmade Music to show off the work he’s doing. Check out the lineup on our new, evolving Handmade Music minisite:

That’s free, 7:30pm Thursday, May 21 in Brooklyn at 3rd Ward.

For fans of Android, I’ll be talking about development on Google’s own open source, Java-based mobile platform, which also runs the Linux kernel.

Android is itself getting ported to alternative platforms, again thanks to the magic of GNU/Linux and open source. Here’s just a small sampling:

Android Ports and Hacks Round-up

If Android also gives us native library access, it could become powerful for music. Even with just the 1.5 SDK, there’s a Java library for interactive music production. Both projects should cross-pollinate, though, because of the common Linux kernel between them.

If you’re not in the New York area, we’ll post details early next week about a live webstream. And we should have additional video after the event.

Hans and I are also working on getting Pd running on the BUG, which is both open-source software and hardware.

To round things out, here’s a video by Public Radio International’s Takeaway, showing how Hans is working with hackers doing other super-cool projects at Brooklyn’s NYC Resistor. It’s just one of many hacklabs sprouting all over the globe.

Humans Turning Up Volume In Oceans [NPR “Science Out of the Box”]

A new report shows the way in which sound travels through the ocean has been impacted by global warming. A growing community of artists are working in media like sound to address environmental challenges. But it seems the planet is making some “sound art” of its own. Curious to hear what people think of the report.

Digital music is extending more deeply into the physical world, thanks to sensors and robotics. The result: gorgeous acoustic sounds as part of the lexicon. When we last spotted Simon Kirby and the Found Electronics collective, they were taking the tangible interface out of electronic music and applying them to ambient sampled sounds out in the woods. Now, they’re talking to plants and channeling traditional Chinese instruments.

Found Electronics: Three Pieces Project Page

Simon writes with some of the details:

It’s called "Three Pieces", and it’s our attempt to create an interactive musical installation that is in keeping with the natural environment of the beautifully restored Victorian Palm House. Rather than use computers and a PA, we decided to try and build something completely acoustic. In the end, we’ve got a traditional Chinese dulcimer and 12 chimes spread throughout the plants and foliage of the Palm House. The instruments are played robotically, controlled by two Arduinos. Motion detectors and a soil sensor allow us to react to people in the space and to the state of the plants to remix the music we’ve composed especially for the installation. The result is a strange combination of traditional and modern, organic and electronic, nature and artifice. Despite being composed in advance, the music will never be exactly the same twice, in part because it will change in response to the environment and audience, and also because the robots are a combination of accurately machined parts (e.g. mechanical solenoids) and natural materials (e.g. bamboo canes).

The installation will be open from Saturday [June] 14th for two weeks. On Saturday 21st, there will be a performance in the Palm House by the band Found for midsummer’s day, and we are planning a Q&A session for the public sometime in the two weeks, to be announced on our website: www.foundelectronics.net

You might also be interested in the other work we’re doing, also on www.foundelectronics.net. For example, we’ve been developing a purpose-built combination of audio-looper software and controller, which is quite fun…

The “mood” of the musical robots is actually affected by the plants:

The moisture content of the soil changes slowly as the plants absorb water, while on a much faster timescale, the temperature changes in the building as animals, including humans, move about. The installation detects this living presence in the Palm House and the music changes accordingly. The robots react to humans, but their mood alters with the plants.

The show has been extended through July 13, so if you’re near the Royal Botanic Garden, you can go have a look!

Last month, I was lucky enough to head to a gathering of music and visual artists at the studio of artist Duncan Laurie in Jamestown, Rhode Island, accompanied by performances in Providence and Boston. Among the cast: Richard Devine, Josh Kay (Phoenicia/Schematic), Steve Nalepa, Todd Thille (Synesthete), Vidvox’s David Lublin, Josh Randall (Robotkid/Harmonix), Aerostatic, Brian Kane (former Emergency Broadcast Network), and Ooah (Glitch Mob).

And then there were the rocks and coconuts. Duncan Laurie and electrical engineer Gordon Salisbury have been sonifying natural signal sources, hooking up vintage radionics equipment and connecting rocks and bananas and such to signals. Richard and Josh brought along part of their formidable collection of modular equipment, and a great crackling, screaming analog racket resulted.

Fans of vintage gear, big knobs, and audiovisual mayhem will surely be jealous. (Photos above courtesy Todd Thille, Arrow.)

Here’s co-organizer Todd Thille (aka Synesthete) describing the full event.

Mind Meld 2008 – Event Wrap by Todd Thille

Todd writes: The weekend of Friday the 13th marked the 3rd annual Mind Meld gathering at Duncan Laurie’s Jamestown, Rhode Island studio. An incredible assortment of audio and video artists were assembled, ostensibly to relax, but with so much talent in one place, a show or two is inevitable.

Duncan’s three-storey studio sits atop Bull Point, surrounded by water on three sides. The studio was built entirely out of salvaged materials. Floors made of glass block allow light to penetrate up from the lower workshop, through the main room and into the laboratory on the top floor. It is on the top floor that Duncan and his electrical engineer Gordon Salisbury have been experimenting with sonifying signals from Nature. There is an impressive array of old Radionic equipment as well as a number of devices that Gordon has developed. The visual centerpiece of the lab is the "Music Machine", an 8′ tall cuboctahedron that was part of a GENESIS Bio-Entrainment Module, a bio-feedback device developed in the 1980’s. The machine is now host to Gordon’s Purr Generator. The purr generator is a device which generates a signal at approximately 25 Hz. This coincides with the frequency of vibrations given off by a “happy cat” and has long been thought to be therapeutic. External audio sources can be played through the machine.

Much of the activity at the studio in the last few years has been given over to exploring signals in Nature. Based on precedents set by Cleve Backster and T. Townsend Brown, plants and rocks are fitted with electrodes or have copper leads affixed to them. Small voltages present are picked up with a variety of test equipment, including Wheatstone bridges, rate of change convertors, EKGs, and the IBVA brainwave monitor. The resulting data streams are converted to MIDI and used to drive Ableton Live.

For the artists that have assembled each year, the draw of a fantastic location, strange nature research and wealth of information about Radionics that Duncan posses are too much to resist. This years gathering included mainstays; Steve Nalepa, a West Coast electronic musician, gaining attention with his forthcoming Flatlands CD/DVD and Bass Science, a dubstep project with MattB; Todd Thille ( aka Synesthete ), an Istanbul based VJ and multimedia artist currently engaged in designing new software and hardware for the explorations underway at Duncan’s studio; David Lublin, of Vidvox, makers of the popular VJ software VDMX; Josh Randall ( aka Robotkid ), a Creative Director at Harmonix by day, working titles like Rock Band and Phase; Aerostatic, the Brooklyn based couple Michelle Darling and Terry Golob, who’s style ranges from ambient to breakcore with some Seseame Street (both have worked at Sesame Workshop) in for good measure.

Newer faces included Brian Kane, a former member of EBN and the self described "Karl Rove of the art world, who was busy pushing his latest meme, Meat Water; Ooah, one of the members of rising stars, the Glitch Mob; Richard Devine, still recovering from a near death experience after a small wound on his foot, infected with staph, nearly destroyed his heart, came to reek sonic mayhem with a massive stack of modular synths; Josh Kay ( aka Jeswa ), who joined Richard in exploring the sonic possibilities of the studio, and a formidable force in his right as a member of Soul Oddity and Phoenecia and founder of Schematic Records; CDM’s own Peter Kirn rounded out the list of performing artists.

Through the work of Elizabeth Keithline and Nick Bauta of The Steel Yard and Firehouse 13, the audio visual extravaganza, "we’ll do it live" found a home at the Pell-Chafee center in downtown Providence. Two massive 40′ wide screens were hung from the three-story vaulted ceiling. Duncan and Aerostatic opened with an exploration of signals coming from a piece of granite (seen in their Rockstar short) and a banana. Peter Kirn deftly handled Kore for his 30 minute set with reactive visuals by Synestete. Brian Kane performed selections from his triple-head av masterpiece, HDADD. Robotkid and rndm threw down a bumpin’ av mashup. Nalepa and David Lublin got the party moving with Flatlands remixes, dubstep tracks and ethereal hand-held footage with Quartz Composer overlays. Ooah brought out the glitch hop with his Panty Raid and tracks from other Mob members. Richard Devine and Josh Kay double-teamed Traktor, bring the soundsystem down with meters in the red and finishing out the night with TapStereo.

The event picked up and relocated to Duncan’s studio where Richard and Josh Kay set up a wall of modular synths to plug into the different sound sources. Peter got busy writing an FFT patch in Processing and tried it out with signals coming from an onion and a lime. He also experimented with Gordon’s Bat Box. The rest of the crew amused themselves with Rock Band and chatting in small groups around the bar-b-gue that sprang up on the driveway.

The group started to disperse on Sunday and everyone but Richard and Josh Kay had left by the time that Steve, photographer Arrow One, Peter and I headed up to Boston on Monday night. We met up with Robotkid and Brian Kane for a show in Cambridge at Beat Research. There was a good crowd despite it being a rainy school night. Peter had much better control over his Kore set. Robotkid and I mixed visuals until Brian fired up his DVJ and played some of his AV pieces. Nalepa came in a pinstripe suit and tore up the room with Bass Science dubstep.

Peter and I started Tuesday morning at the new offices of Harmonix. We decided not to get sucked into any meetings and beat a retreat to the MIT Museum. There were good exhibits on deep sea craft, high-speed photography and sculptor Arthur Ganson.

The afternoon brought a visit to the studio of visionary painter Paul Laffoley. He had requested a chicken stuffed in a watermelon, potential racial slur aside, we obliged and hand delivered him a "chelon." Paul was in the midst of prepping for a 60s and 70s retrospective that is to be on display in New York in February. He was also hard at work on a Tarot deck. We parted with Peter afterwards and the 3rd annual Mind Meld came to a close.

Tired of all those DIY electronics projects making an awful racket? This one is whisper-quiet. You may have to turn up your volume to hear it at all.

Project creator Andrew Benson (maker of many wonderful things for Cycling ‘74) writes:

I just finished sewing together an FM synthesizer that lives on a wristband and is controlled by a little brown button that serves as a knob and a pair of small pressure sensors made from conductive fabrics. The whole thing runs off of an attiny45 chip, which is a really cheap AVR microcontroller chip that I’ve programmed with some FM synthesis routines.

It is a quiet little noise-maker, and is super fun to play with. All of the electronic connections (except for the little hand-routed PCB) are made using conductive thread. I’m still working on some finishing touches like strengthening the weak points with embroidery and providing slightly better protection for the circuit, but the functionality is all there. Let me know what you think!

As it happens, one of my favorite projects from the spring ITP show at New York University was the Square Band by Rory Nugent:

A wearable, portable square-wave synthesizer designed to be worn around the wrist so that he or she can be musically expressive whenever the moment strikes them.

Rows of buttons run along the underside of the wearer’s wrist for triggering of musical tones and a light sensor is available for shifting the pitch of the tones being played. This design allows for a form of musical expression that integrates itself very intimately with the human body. Tapping with the fingers plays tones and movement of the wrist and arm shifts these tones in pitch up and down.

Solar panels? Fun, simple beat making? I’m sold.

Whether this appeals to you or not, you can bet that the growing availability, cheapness, and ease-of-use of small microprocessors will mean synths everywhere. Could be even cooler than that Dick Tracy wrist phone, after all.

But that got me thinking. I think for creative health it’s important to spend some time out waterskiing or birdwatching that isn’t musical time. But what about those time when you have music making to do and you have to reconcile it with pretty outdoors time? Have you found a mobile setup that you take with you to the park? Let us know. Maybe I do need one of those HP Mini-Notes like our friend Brad just picked up. Some micro PC, solar power … sounds rather nice, right?

And if you’ve got an image of you, a keytar, and a surfboard, or perhaps a solar array powering a mountain-top Reaktor programming session, send them our way!

Updated:

That didn’t take long! Here’s Soundfreaks playing, complete with keytar and Speedo, on a lake outside Munich. Nice one, guys. Now, I just need a waterproof computer…

Logic’s Environment, a modular layer in the program for creating custom configurations, isn’t well known to many Logic users. But if you can get used to its slightly unusual interface, it’s capable of some really powerful stuff. You know, important music stuff. Like connecting Logic to your Nintendo NES game system.

The MIDINES evironment was created based on this chart:
http://www.wayfar.net/0xf00000_midi_chart.php

The environment allows for control of the 5 channels of synth/audio that the NES [supports]

Here are the 5 parts:
1-2 – Pulse Synthesizer waves
3-4 – Triangle/Square waves
5- sample channel

Since this is also my primary template for a Logic session there are other goodies I left in there:

1. NYC compression bus channel
2. 3 bus channels that I got from Hybrid (electronic group) for simple drum processing
3. MPC groove templates taken from an MPC 60
4. Ableton Live and Reason ReWire objects

There you have it: Logic + NES + MPC + Live + Reason. If that’s not a digital dream studio, I don’t know what is.

That’s the MIDINES, Logic 8 file (if anyone has a MIDINES but Logic 7, let us know and we can share the Logic 7 file.)
