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.

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:

This charming music video from Charlie North imagines creating your own simple music controllers with a piece of paper and a marker. (There’s some similarity to M-Audio pieces there, too.) Of course, that raises another question: could this actually be done?

Computer vision isn’t quite intelligent enough to work out automatically what’s going on here, but it seems to me that you could get a little closer. Another alternative would be using conductive ink or graphite to make the drawing itself a sensor. I’m going to leave you to puzzle out the rest.

It’s technically still a holiday weekend here in the U.S. of A., so I’m going to keep with the whimsical inspiration for the rest of the day.

Nat “funnelbc”, creator of the CDM logo and graphic appearance, took on a project the rest of us at Team CDM thought was completely insane: make 28 gig posters, in 28 days, for free.

Miraculously, Nat has escaped alive, and the results are fantastic. Good luck paying a designer to give you gig posters like this. These two warm my heart because of their digital music create-i-ness:

Gig Posters Archives

Have a gig coming up? Need a rocking poster to publicise said gig to the wider community? You should check out Nat’s 28 Posters in 28 Days Poster Challenge! You know you’re going to get a great result, because Nat designed this here website, and CDMo, and the forums. You should get in quick, however, because he doesn’t seem to be starting out in the most positive frame of mind:

They said I couldn’t do it! My girlfriend said I couldn’t do it. I don’t think I can do it… Let me preface this by saying that I have a sneaking suspicion that this isn’t one of my brightest ideas. Good? Clear? Okay.

For the month of February, I am going to attempt to do 1 FREE gig poster per day.

That means I need details for 28 gigs and bands who want posters done. Starting tomorrow, the 1st of February. 

Visual Acoustics is an online musical toy built in Flash designed by Alex Lampe (”Ample Interactive”) of the UK. (Via Music Thing.) The motion visuals are beautiful, and the music and interface is very reminiscent of Toshio Iwai’s work (see Nintendo’s ElectroPlankton, for instance). As with Iwai’s designs, just about anything you play will sound good and ambient. Now, there are two schools of thought on that. One suggests that these kind of futuristic interfaces make music accessible to anyone. The other would hold that part of what makes traditional musical instruments lovely is that, while they take a long time to learn, the rewards are much deeper. I’m not sure one is inherently better than the other, but I still wonder if it isn’t possible to build visual interfaces that are harder to master but deeper to play.

If you want some inspiration for moving in either direction, Visual Acoustics certainly shows potential. Now you just need a Wacom tablet-enabled version that, rather than conventional sliders for parameters, adjusts to gesture and pressure.
