Musical makers at Maker Faire '09

Scottish sound designer, the Amazing Rolo, traveled to Maker Faire this year especially to see what sorts of cool musical technologies people were cooking up. He made a series of videos of makers demoing their wares. Of the three videos above, he writes:

First up is Elly Jessop, a Masters Student at the uber-cool MIT Media Lab, and her Vocal Augmentation and Manipulation Prosthesis (VAMP). Next is Barry Threw, from Keith McMillan Instruments, showing off the K-Bow (and accompanying software) for extending stringed instrument performance into the digital realm. And finally, the amazing Moldover and his totally bonkers Syncomasher.

Spinner synth

Matt Mets made a rotation-based MIDI controller using a motor, disc, webcam, and OpenCV. Source code included.

Tangible drum machine

Here are instructions for building a drum machine with a tangible visual interface. A camera above the paper drum board reads the positions of physical objects and translates them into sounds, as indicated on the labels on the objects. It looks fairly easy to make, with most of the components from paper and card.

Beat-slicing with OTTO

CDM points out this very sweet beat manipulator interface by Luca De Rosso. The project, better known as OTTO, makes use of an Arduino board, MAX/MSP software, and an array of LEDs + switches to create a very intuitive and approachable experience for musicians. -

OTTO is a new musical instrument for beat-slicing, the technique that allows to create complex and variegated rhythm sections by using just one rhythmic audio sample, cutting it into little pieces and rearranging them in time. OTTO provides a hardware solution with a strong visual feedback, to allow the musician to control the audio sample as if it was in his hands.

Circular sequencer devices really seem like a step in the right direction for audio hardware - much more intuitive for loops. More demo vids and source documentation/downloads available on the OTTO site

Etched-brass modular synth

This supremely cool analog synth with a gorgeous etched-brass faceplace showed up on Steampunk Workshop, via the German synth site Synthesizer Database. The builder is Moritz Wolpert. Apparently, from the Google translation, all the knobs and handles were turned by hand on a lathe and the faceplace was hand-lettered, decorated and etched. The project took him two years.

How-To: Droning machine

Randy Sarafan's band has got to be set up by now, he built his own droning machine from the movie Eli Eli Lema Sabachthani.

Shopping-cart serenade

Not since industrial noisemakers like Einsturzende Neubauten first miked a shopping cart... This is a decidedly more 21st version. The makers, Hogan Birney, Sean Kinberger, and David Plakon explain the design:

Touch and pressure are used to control the live manipulation of sound and image. The cart is equipped with a video projector, computer and battery making it portable and self contained. Using a microprocessor (Arduino) and custom software (max/msp/jitter) to sense the users touch and translate the pressure of the users touch, a real-time response is created both visually and sonically. The cart is used by MPG performers and the audience is also encouraged to play the cart as well.

How-To: Circuit bending Casio SA keyboards

Uber-bender Pete Edwards of Casper Electronics shares his recipe for cooking up some tasty mods for Casio 'SA' series keyboards -

This is an engineered modification which works on most of the Casio SA series ( SA-1, SA-5, SA-7, SA-8 etc). There will be an Amplifier chip ( No AN8053 ) common across the SA series and a mask programmed CPU which will be made by OKI and have the part No M6387-xx where xx is the variant for the specific keyboard it is installed in, in the case of the SA-5 it is M6387-16. The different variant number accommodates different key / button layouts of the keyboard it is fitted into, the PCM sounds however remain the same. There are 5 interesting modifications that can be easily fitted:

1) Pitch Shifting
2) Power Crash
3) 5th's Switch
4) Glitch Randomizer
5) Filter/ Feedback Adjustment

Oodles more info + sound samples available of @ Casper.

The Furby Youth Choir

Those of you who attended Maker Faire 2008 in Austin may recall the performance of local circuit-benders Furby Youth Choir. I recently had a chance to attend one of their live performances at the United States Art Authority, next to Spider House on Fruth St. in the UT Campus area.

A Furby, for those who were living in a bunker preparing for Y2K during their vogue, is a robot toy that looks a lot like Gizmo from The Gremlins. They talk and sing and move their mouths and eyes and other neat stuff, including reacting to their environment and, to an extent, "learning" certain patterns of behavior. The large feature set makes them popular with hackers, especially circuit benders.

Anyhoo, as one can imagine, a small army of them singing on-stage is fairly unsettling. What's more, FYC's music is decidedly avant-garde, dissonant, and ominous. Two performers stand over a table covered with circuit boards and wires and bend the aforesaid circuits in real time. Add to that mix a video projector beaming twisted animations and other visual psychedalia upstage, and the whole experience becomes a bit....overwhelming. US Art Authority is a small venue, and to my 25-to-34-year-old ear, they were rather too loud for it, but they still get huge points for originality. If you get a chance to see them, you should. Just be sure to pack a pair of earplugs.

Make your own radio programming

[Photo from MetroMode]

Michael Jackson's death caused radio's roboprogrammers to take a back seat for a while. Increasingly, over the past few decades, broadcast radio has ceased to be a local affair. As the FCC regulations on local ownership of media outlets has faded towards corporate behemoths, radio programming more and more these days is done by databases and distant decision makers. For those of us who remember real radio dj's who made personal decisions about what song would come next, this has driven us more towards our own music collection, rather than being stuck listening to the corporate drivel. Pandora and Last.fm are okay, but they lack the personal touch.

With Michael Jackson's death announcement, the clacker driven music machine was taken off line, if only for a few hours and only on a few stations. Human beings again ruled the airwaves of some radio stations.

"It's a good reminder of what live radio can do, of the role that radio can play in bringing a community together,'' said Scott Fybush, editor of Northeast Radio Watch in Rochester, N.Y.
Many stations no longer have live announcers, using canned voices for part or all of the day, and so can't react to a major news event, he said.

DJ Deirdre Dagata, 39, has been working at Mix 98.5 part time since May, after being replaced at Kiss 108 by recorded programming the month before. And yesterday, she was back in action for the biggest radio day in memory.

Dagata was in constant motion during her 9 a.m. to 2 p.m. shift. Sitting in an elevated office chair in front of four computer screens, she punched blinking phone lines, tapped on keys, and slid knobs - simultaneously editing recorded calls and fielding a steady stream of new ones from listeners who wanted to share stories about Jackson.

Back in the day, I recall listening to the radio knowing something unique was happening. The radio announcers had their own tastes in music, and they helped to create a following around their musical tastes. Sometimes there was dead air as the dj missed the cue for a variety of human reasons, some more innocent than others. This caused me to volunteer at and work at several radio stations in the 1980's and 1990's. I actually chose my university because I liked the on air feel of the campus radio station, which turned out to be a very influential organization for me. At the station, I did on-air work, production of public service announcements, newscasts, dj training, and eventually became Program Director. The audience's active listenership of the music and programming was exciting to be involved with.

Back then, radio was a public service to be provided to the community, not just a marketing opportunity. Almost radio programming was done with people at the microphones, nearly always they were playing actual records, tapes or cds. Even the commercials were created in-house, except those for national campaigns.

Do you miss real radio? There are a bunch of college radio stations around, and most of them depend on the student body and sometimes local community members to create their programming. With web streaming, it is possible to listen way beyond the broadcast range of your favorite station. WERS in Boston plays a good mix curated by communications students. KEXP in Seattle has a wonderful mix of live performances and genuine djs choosing the music they play. Transom and Youth Radio are helping to cultivate the new voices of radio that we need. Public Radio Exchange has a channel on XM radio, and features a mix of voices that you may not have heard before.

With podcasting and the great suite of computer software and hardware available for free, just about everybody has the radio recording studio in their laptop, desktop, cellphone and digital camera that I had in my bedroom as a high school kid. If you want to broadcast, you may want to build your own transmitter. Sending out your homebrew radio programming out to your house or close neighbors could be a neat experience. You could record some short pieces like songs, jokes, or seque buffers, drop them into your music library and set your music player loose, sending your personalized radio program out to the transmitter.

Radio used to be a LOT of fun as a listener and programmer. Now the tools are much easier to get and use for us regular folks. Hopefully, the corporations will lighten up on their centralized programming and return to the human touch of radio, but even if they don't we can realize that we can choose what radio we listen to or create. If you have any stories of making your own or listening to real radio, pirate or otherwise, tell us in the comments.

Prototyping Thermatron, flame-controlled synth

Lorin Parker of Electric Western (creator of the Phantastron) puts fire to work controlling sound -

The THERMATRON is essentially a voltage controlled oscillator and wave shaper controlled by the action of a flame. This is possible because electricity can be conducted through a flame. This is not a new discovery, in fact the electrical properties of flame have been known for hundreds of years and well studied. For example, many hot water heaters have a sensor that detects flame by sensing the current inserted through the gas flame (if the gas flame goes out, the current does not reach the sensor and the heater knows that the flame is out).

Check out the project's post for a much deeper explanation of the Thermatron's funciotnality and flame conduction in general.

How-To: Make an audio cassette tape loop

Instructables author (and Community Manager) Randy Sarafan writes:

Theoretically it sounds really easy; you can make a tape loop by taping the ends of a short piece of magnetic ribbon together and sticking it back inside the cassette tape. However, if you ever actually tried to do this, you will soon realize that it is a tad bit trickier than one would think. I spent an afternoon working out and refining this science. After many tries and many, throw-my-hands-in-the-air-and-promise-to-give-up sorts of moments, I think I have it down reasonably enough to write instructions for someone else to do it. Now you too can tape the ends of magnetic ribbon together, and profit!

Getting to know the diode mixer

Dave posted this vid along with a write-up, covering the ins-and-outs of the unbalanced diode mixer circuit -

This circuit uses the small non-linear response area of a single diode to create combinations of sum and difference frequencies of two input signals (or one input signal containing multiple overtones). Radio designers use this type of circuit to "downconvert" received RF signals to a lower intermediate frequency, which makes it a lot easier to design the radio's signal processing circuitry. We can use the same circuit for electronic music to generate non-harmonic overtones. (In the RF circuitry literature, there is a class of related circuits that all use diodes to do frequency mixing functions. What we call a "ring modulator" originated as a more sophisticated version of the circuit presented here.)

Much more info + schematic available on his blog entry.

Brian May's homemade guitar

Seven Sexton sent us a link to this awesome 1992 video of Queen's Brian May talking about "The Fireplace," his famous electric guitar that he and his dad built from scrap bits such as a mantle from a 100-year old fireplace (hence the name), a chunk of a table, a spring from a motorcycle, a piece from his mother's knitting needle, etc. Amazingly, this is not some fragile relic he keeps in the closet, but a working guitar, one you've heard on many Queen songs. His family was poor and his dad built most of their home electronics, including their television and radio. Wonderful, inspiring little piece. I love the opening quote from him:

I'm still a kid. Basically, I LOVE the sound of the guitar. I love making it. I love standing there and making that noise.

Performance with 64 helium balloons

Robert henke & Christopher Bauder made this installation/performance piece called Atom:

A room is filled with deep, evolving noises from a four-channel sound system. An eight-by-eight array of white, self-illuminated spheres floats in space like the atoms of a complex molecule.

Through variable positioning and illumination of each atom, a dynamic display sculpture comes into being, composed of physical objects, patterns of light, and synchronous rhythmic and textural sonic events. Change, sound, and movement converge into a larger form.

The height of each helium balloon is adjusted with a computer-controlled cable winch, whilst the internal illumination is accomplished using dimmable super-bright LEDs, creating a pixel in a warped 8x8 spatial matrix.

The sonic events, the patterns of light, and the movement of the balloons are manipulated in real time as a 45-60 minute-long performance.

(Thanks, Tom!)

Junk Box Monome

MAKE subscriber Mike Cook built a Monome-style controller interface from only spare parts! (granted he seems to have some very nice spare parts lying around) Behold the Econo Monome -

The official Monomes have always had a nod towards eco friendliness by incorporating renewable wood in their construction. Well I wanted to go at least one better and use parts that I already had in my junk box. Let's kick off by saying that 40 years of working, and playing, with electronics has given me a junk box that is perhaps deeper than most people's, your mileage may vary.

Definitely my fave incarnation of the Monome yet - head over to the project page for interesting deets on everything used to build it. Next time I need to 'borrow' some spare components, I'll consider dropping Mike a line ;)

Spinning sounds with the Servo Seq

Gijs Gieskes introduces another intriguing musical machine, the opto-sensing multi-armed Servo Seq -

The frequency circles speed can be set with a pot on the controller. The arms can be sequenced with the three buttons on the controller, in combination with the joystick.. If the joystick is moved up, the volume will go up for the arm that is being controlled. Moving the joystick left and right will change the position of the arm. On the tip of the arm there is a line detector, that plays back the frequencys, but the arms can also hit objects placed next to the circle to make drum sounds.

The Seq's brain consists of an ATMega168 configured as an Arduino compatible - more info, code and even a web app for generating compatible disc patterns are all available on the relevant project page. [via Create Digital Music]

Musical gadget: Nao-Min

The Nao-Min is one of the more unique instruments that I have come across. The sound is very Theremin-like and the controls are really clever. Check out the video below for more about how the Nao-Min works.
