Artists Gijs Gieskes’ sequencers are almost like physical, mechanical software, an expression of musical structure in object form. As such, even as they make strange sounds, they become musical sculpture. His latest Servo Sequencer combines optical and mechanical process, as frequency circles spin on a turntable and tone arms float above them.

The Servo Sequencer is built for exhibition use – meaning, yes, he’s brave enough to let you play with this contraption. Sequence the arms using buttons, then adjust the volume mix and placement of each arm using the joystick.

This project is unusually well-documented. Gijs provides complete specs, the script that controls the arms, and even a little web app that generates those lovely patterns.

But for those of you near the Netherlands, you should go check this out in person. Updated: The piece will be part of an exhibition in Breda through August 23, with multiple opening events featuring local artists from Eindhoven and Breda, plus live performances and concerts including Gijs and his talented brethren and neighbors.

Here & There Exhibition, mu.nl [Info in English]

The events:
Opening Part 1:
KOP, Breda
Thursday 25/06 08.00 pm

MU, Eindhoven
Friday 26/06 08.00 pm

(It’s a bit confusing as the events swap between Breda and Eindhoven — there’s a second opening Saturday July 25. Gijs explains “the first [opening] is in breda (thursday), then a day later (friday) in eindhoven, where my machine will be. and then a month later its the other way around.”)

You know, Breda. Like, right … here. We’ve got a number of readers in the area (whom I suspect know more or less exactly where this is); let us know if you make it!

If you’re interested in generative and algorithmic music – music that evolves organically rather than being pre-composed in start-to-finish linear fashion – you won’t want to miss this site. Nodal is a free (for non-commercial use) app for developing generative musical systems and transmitting MIDI. You’ll need a Mac (PowerPC/Intel) to run the software, but even if you’re on Windows or Linux, you’ll find a number of interesting research papers on the site. vinayk writes:

The program is called Nodal – osx only, BEAUTIFUL interface, and FREE, it does a bit more sophisticated things but I basically plugged the output into sculpture – and it sounded amazing… well worth a look! And if anyone can tell me how to sync this to live or logic then i’d be much obliged!

Since it sends MIDI, it’d also be interesting to use this hooked up to visuals or triggering clips in Ableton Live.

I’ll be giving this a try soon. If you know of other generative software and research we should be checking out, perhaps we can put together a full round-up.

See also Noatikl / Mixtikl, from Intermorphic – developers who built the ground-breaking Koan generative system for Brian Eno. And we’re getting close to the release of the game Spore, which will feature a new generative engine and Eno’s composition.

Generative iPod? Deep Modular, Generative Music System Bound for iPhone, Phones, Windows, Mac

(Note that we learned this week that Mixtikl is not coming to iPhone in the immediate future. It’s available on plenty of other platforms, however, and if you’ve got a Mac for both, let the generative music making commence!)

Mari Kimura is an experimental string player extraordinaire, regularly venturing to the edge of what’s possible at the meeting of acoustic and electronic technology. GuitarBot is a “guitar”-playing robot (perhaps more reminiscent of a shamisen), an invention of Eric Singer, founder of the League of Electronic Musical Urban Robots. The two meet above in a lovely video – not new, but well worth watching any old time, as reminded to us by Richard Swelling’s Etherbomb blog. Mari writes in comments on YouTube:

HI, Mari here. For those wondering what’s happening: Behind the white box, there is a Mac and an audio interface. I am running a software MaxMSP, which is LISTENING to the pitch. loundess and the timing of the violin. The ‘patch’ I created in Max contains certain interactive instructions such as "listen to the E (highest open string on the violin)". For example in the beginning, if you listen carefully you notice when I play above E, it stops. Iinteractions change in predetermined time frames.

It’s a reminder that, technology aside, the key ingredient in electro-acoustic music is great musicianship.

Quite nice stuff! And the video is shot by my friend Liubo Borrisov; Liubo, if you’re out there, say hi.

CDM contributor, mic flag fabricator, beat bicyclist, and sound artist extraordinaire Michael Una has been up to more sonic magic-making in Chicago. He showed two recent creations at MGFest 2008 — that’s MG as in “Motion Graphics”, not, sadly, the car, though I think sound art would also go deliciously with MG automobiles.

On display in Chi-town: giant pods to fill rooms with sound, and a man in a sound-induced, hypnotic blizzard of milk. (Yes, they have winter in northern Illinois.)

Behind-the-scenes commentary is available on Mike’s site, not to be confused with the domain-squatting personals site that you get if you leave out the hyphen. (Will, someday, an entire romantic community be devoted to Una Love? I wouldn’t rule it out.)

One lesson learned: milk can be incompatible with electronics.

Reel to Wheel is a massive sound-making device built from bicycle parts and a dismantled reel-to-reel tape deck. Move around the absurdly over-sized controls, and its analog inner workings groan and creak their way through recorded sound. Move the wheel at the right speed, and you get an effect quite like scratching — or, since it’s tape, it’s really “scrubbing.”

Reel to Wheel Project Page, with wonderful hand-drawn illustrations featuring Hank the Dummy.

The project, shown last weekend at the Maker Faire, is the creation of Sasha Leitman, Steven Backer, Jesse Fox, and Jen Carlile at Stanford University’s Center for Computer Research in Music and Acoustics (CCRMA), which had their own booth full of musical interfaces and goodies. Like an equally Biggie-Sized string instrument, Reel to Wheel delighted adults and terrified children with its elegant impracticality. If it seems like sculpture, that’s because it is. In the installation version of the same work, the hardware is part of a Rube Goldberg-like configuration of bikes on mannequins and full-sized stationary bicycles.

This work also suggests that this site has stumbled upon a really bizarre, evolving musical meme. Look at the elements:

Bikes. Our friend Flip Baber created a new arrangement of the Dance of the Sugar Plum Fairy in December, recorded on bike parts. Much to our surprise, this story landed on Digg and launched to the most popular CDM story ever (promptly devastating our server), and Flip wound up on television and national radio. As it turns out, quite a lot of our readers are interested in music made with bikes, including bike ensembles, symphonies, and bikelophones, and bikes that control music and graffiti and inspire a young Frank Zappa.

Reel-to-Reel DJing: Because no one can beat-match on reel-to-reels like BBC Radiophonic Workshop wizard Delia Derbyshire.

So, I’m a little terrified that we’ve hit upon some strange statistical anomaly that seems to be tapping us directly into a musical world entirely based on tape and bicycle technology, but I’ll go with it.
