Imagine drawing an interface on paper, then being able to use it as a musical interface. Or, heck, don’t imagine it – do it. Unfortunately, the kinds of intelligence necessary to make the music video in yesterday’s post just aren’t practical yet. (That is, you could draw a picture of a keyboard, and even use the picture as a music controller, but while you or I could recognize a keyboard from a drum pad and know that line is a fader, a computer would need some sort of advance structure for any recognition to work.) But you can do some really clever things, as folks have shared in comments.

And using some basic paper interfaces, you can make entire instruments for just a few dollars.

Of course, the awesomest way to do anything is with LAZORS. Greg Kellum and Alain Crevoisier presented a paper at last year’s NIME (a conference for new interface designs for music) proposing a system for making any surface a control surface. Like the music video yesterday, you can configure your surface to function however you like – even dividing it up into pads and faders.

By now, you’e likely seen plenty of multi-touch interfaces or means of tracking hands. But, to paraphrase the NIME paper, these either require a special surface (or transparent surface), or they can’t actually detect when you’re touching. You can even use multiple cameras or an IR beam, but there are limitations to accuracy and the size of the usable surface that would result. Kellum and Crevoisier use an infrared camera and two illuminators, each built by pointing a laser at a mirrors.

Yawn, you say, been there, done that, seen Jeff Han’s video… The advantage of this system is that you can use any surface, like your dining room table. And you can configure that surface however you like. There’s even a freely-downloadable Surface Editor you can extend in Java and Processing. The creators claim they can even get input latency down to a reasonable 10 ms using high-speed cameras.

Thanks, Randy Jones!

db3ll has created a keyboard out of paper, and of course it works better than those flimsy rubber “roll-up” pianos you see for sale. “Conductive ink is what I used,” he says, “painted on as traces on the non-printed side of the paper.” That’s the twist – I had assumed you’d use the top of the paper, but the trick is to use the reverse side to provide the “wiring.” He also offers advice for making a fader:

Amanda Ervin makes elegant noise-making apparatuses from simple circuits, and is able to share that process with her students (see her classes among 3rd Ward’s Circuits lineup). She’s going to show off some of her latest creations at the open showcase of Handmade Music Brooklyn, our monthly party + science fair + musical performance + ruckus. (More details soon on Handmade Music events that are springing up worldwide, thanks to the hard work and creativity of the DIY music community!)

What really impresses me about these projects is that Amanda has made both the project and the curriculum – that is, she can teach you to make these, too! It’s often easier to make something for yourself alone than it is to make it reproducible, so I do admire that in a design.

If you’re in the New York area, you can catch the event free, Thursday evening September 17. (Directions) If not, we’re working with 3rd Ward on ways to translate the educational experience online.

Here’s a musical excerpt from Amanda, as well:

Want to contribute your work? If you can make it to NYC this month, we’d love to present your work. All projects, all media (electronic, acoustic, hardware, software), and all levels of functionality (working, partially working, in-progress, completely broken) are welcome!

Handmade Music 9/17 Call for Works [Google Docs form, also embedded after the jump]

Here’s someone who really, really loves Native Instruments’ B4 (II) software rendition of the Hammond B3 organ. The work of Markus Berger, this dead-ringer for a real B3 is actually a carefully crafted replica with elaborate MIDI control inside. The body is built by hand from cherry wood. Electronics were prototyped with the open source Arduino platform and implemented with electronics from Doepfer, then finished with manuals (that’s “keys” for you non-organists) from Fatar (as seen in Nord’s organs). Authentic-style drawbars finish the project. Correction: I got my wires crossed and originally claimed this had Fatar drawbars, but it’s Fatar manuals. Thanks to comments for spotting that.

The integration of the hardware design with the B4 is extraordinary: the creator notes that every single function is perfectly replicated, so you never have to touch a mouse or look at a screen. Of course, you can then make meticulous models tweaked on the B4 software that wouldn’t have been possible on the original hardware – and this hardware, while substantial, should be dramatically lighter.

More on those custom electronics:

The main controller electronics were actually custom developed and prototyped with Arduino. They were complemented by electronics from Doepfer for the two manuals.

Most of the electronics had to be custom developed as there was and still is nothing available to cover all the functionality of a classic Hammond B3 with the full drawbars set, preset keys and all the switches.

And yes, the bottom line is that this puts every controller for everything I’ve ever seen to shame. Thanks to Germany-based Twitter reader tillephone for sending this my way.

I hesitate to even suggest this, but – is a Leslie cabinet next?

Making music into an object – the central genius of recording – could be a wonderful thing. But the CD was always somewhat utilitarian as a distribution mechanism, with its easily-splintered plastic jewel case and inserted artwork that paled next to the grand visions of the LP.

Moldover is the latest artist to experiment with ways of re-imagining the musical object. Already a fan of custom sonic circuitry, he made his CD into a circuit board. Some of it is just aesthetic, like the printed lettering. But there is also integrated noise-making circuitry for a very simple optical Theremin (well, at least, a light sensor-driven oscillator), plus a headphone jack. There’s actually quite a lot of function you can get out of that when plugging into a computer.

The album itself is comprised jazzy bleepy jams (in varying proportions). You do pay for this deluxe, handmade circuit goodness. The US$25 “Pocket Edition” seems to be the sweet spot, with a pocketable version of the circuit board. It still has a built-in speaker, turning the jewel case into self-sufficient sonic hardware instead of a throwaway. The $50 version comes with the full custom-printed circuit board for the track listing, but you can’t pocket it, which means you have exactly $25 and one custom Theremin less in your pocket.

The joy of being on YouTube is you get strange comments like this:

Who let you out? of your mom’s basement? Go back to building lego trainsets to transport your cocoa from the kitchen to your computer desk.

Hey – that’s a great idea, come to think of it.

Justifying the musical object can sometimes get ridiculous, but so long as there are genuinely creative ideas that fit the music, I think music may have a more interesting future in the post-industry world than it did before.

Updated – previous applications of this idea: I’m typing quickly before I head to lunch, and I commit the major sin of not mentioning our friend Tristan Perich’s infamous 2005 release 1-bit Music. Whereas Moldover is turning the packaging into an instrument and inserting a traditional CD, Tristan made the entire jewel box the playback mechanism – the album is embedded in the circuitry, and you listen to it directly.

An electronic circuit is assembled inside a CD case with a headphone jack on the side. The device plays back 40 minutes of low-fi 1-bit electronic music—the lowest possible digital representation of audio.

1-bit Music (Tristan also did a great workshop at Handmade Music. So if you want to play with these ideas, and you’re in the NYC area, there’s only one place you should be tomorrow night.)

We talk a lot about novelty, but my hope is people rip off both Moldover’s and Tristan’s idea here – and invent their own twist on this concept. I’d love to have a shelf full of circuit CDs, instead of dead, silent plastic!

Bored with mouse pushing and knob twiddling? The d-touch tangible sequencer / drum machine makes a cheap interface (with free downloadable software) for assembling sequences. Make some (attractive) blocks, set up a webcam, and plug into your computer. I took a first look at this tool last month, and noted its use in sequencing walnuts. (Yes, the ones that fall from trees.) Since then, the developers have been hard at work on updates. Enrico writes:

We just released the d-touch sequencer, a new, more advanced, audio application. In the sequencer you can record your own samples in real time.

We also have few updates for the drum machine, which should solve the activation problems we were having at the beginning.

Go grab the markers and the software, and you have your own webcam-based drum machine.

Should you decide to go beyond their free instrument, the underlying system is really quite sophisticated. Part of what makes it beautiful is that you can design your own markers rather than settling for predefined patterns, as with most similar marker-tracking systems. There’s even a tool for correcting problems in your design. The freely-downloadable analysis software is written in C/C++, but if you use another environment (like Max or Processing or Reaktor), you can simply pipe data to your tool of choice.

The drum machine and sequencer are available now, so go download them and let you know how you fare! System requirements: a printer, a webcam, and a PC/Mac. Enjoy!

For some hands-on impressions of working with these things, the excellent PC Music Guru has a great description of the experience. Or, if you read the language, there’s a Japanese-language hands-on blog entry.
