Software doesn’t have to mean virtualizing everything and letting go of physical objects. On the contrary, it can create all sots of imaginative, new ways of mapping musical ideas to the physical world. And that’s how we wind up with a walnut drum sequencer.

There’s something about virtual drum machines and snacks. We’ve seen bubblegum and Skittles, beer bottle caps, soda bottles, and now walnuts. Don’t stop now: someone has to do Cheetos, even if it means dealing with orange stuff all over your fingers.

That said, it’s not walnuts that make d-touch an important project. Built by Enrico Costanza back in 2003, the project is now available for free download as an open source library, a server (in case you don’t want to get into the C++ code but might want to use this in your own projects), a free, usable drum machine, and a set of documentation that can help you make your own stuff easily. Enrico worked on the original reacTable prototype and has done some really important work in this field. Right now, Enrico and co are looking for feedback, but if you’re ready to just be a tester and play with this – and see what you can do musically – now’s your chance.

d-touch also combines high levels of computer readability for accurate tracking with the ability to make your own tags. Instead of using ugly-looking glyphs, you can make patterns that make sense to human beings as well as computers. Oh, yeah – and mobile fans, this runs at a full 14 fps even on S60 phones.

Thanks to Martin (of reacTable, which is moving toward a commercial product) for sending this our way. Thanks, too, to Ben, who’s working on tangible interfaces with special needs students. I really look forward to hearing how that’s going.

Greensboro, NC-based art music band Invisible are indiscriminate about technology – in a good way. Plastic cups, keyboards, typewriters, machines controlled by robotics, if it’s in the trash or at a thrift store, it has a place in the band. Sequences are executed in physical, radial player instruments, without a controlling computer anywhere in site. As voicemail tapes get sampled and typewriters tap lines of absurdist lyrics as each typed letter plays a piano note, something magical happens. Perhaps it’s that, novelty aside, somehow these sound-making objects come together for a reason – the machines assemble in the way the band does. And then a chair is a marimba.

The Rhythm 1001 takes “tangible” to a whole new level — everything sequenced is mechanical, triggering found objects. The video above features the sequencer at Charlottesville, Virginia’s Second Street Gallery. (Gents, if you ever visit Brooklyn…) Thanks to Evan Hill for the tip.

Is it “Digital Music”? I think it is very deeply so, perhaps because the objects get treated as discrete musical events (read: percussion).

Incidentally, guys, I agree with a lot of things you’re saying about the use of computers for music, but HAL here tell me he won’t let me fr

As you can see, people have already begun playing with ideas for tangible interfaces. Oddly enough, two German gentlemen each named Michael (not aware of one another) have gotten a headstart, including the first experiment above in progress. We’ll be experimenting with new interfaces in New York and around the globe. (If that isn’t enough experimentation with new interfaces, the NIME conference – New Interfaces in Musical Expression – is happening now in Pittsburgh, and we expect reports back from that, too!) The event has also been featured on Boing Boing and MAKE.

The translation of music from something largely invisible to a physical object is oddly beautiful, even when imperfect. That’s part of why we’re working on the Tangible Interface Hackday – less than 48 hours away now.

Here are a couple of additional sources of inspiration as we prepare.

At bottom, Guy John has made a sequencer out of one of the world’s most ancient games, Go. Over two millenia ago, Chinese people were passing the hours playing this game, so it’s an incredible way of connecting our passtimes today with the leisure time of our ancient ancestors – and a sign that gaming is a part of culture that endures. It’s fitting, too, as a lot of computer musical interfaces can be thought of as games. This particular game uses Max/MSP/Jitter and the CV Jitter externals for image analysis, then translates the game into a grid. Guy’s idea is fairly early in development, so I actually think you could go all sorts of different directions with this basic concept. (As seen in Hack a Day at the end of last year.)

At top, the Graphite Sequencer translates optical images made in the electricity-conducting material to sound in a simple turntable. It’s lovely seeing these patterns as sound objects, especially since usually we go the other way (trying to find patterns to affix to sounds). The same basic graphite-conducting process is used in the business card PAiA kit we showed at a past Handmade Music, as well as the Drawdio pencil (based on the same circuit).

I’d love to see people continue to combine these fairly basic analog-style techniques – or thousands-year-old games – with the newer digital approach. Let us know what you come up with, creative folk.

Digital technology has made music oddly invisible, virtualized somewhere inside a screen – but it also allows music to be mapped more literally to the physical world than ever before. Some of these experiments may even be silly, but they suggest a lot of possibilities.

From Poland, BeatMachine is a project that sequences beats in a step sequencer using discarded beer bottle caps. Would-be Internet haters, I suggest you count the number of beer bottle caps on the table, and start drinking that number while watching. I guarantee eventually it’ll seem like a brilliant idea.

Make sure you keep watching to the clever-looking software they’ve evidently developed for the task.

If this seems familiar, it was in fact inspired by the Bubblegum Sequencer featured here previously, and its rival I Eat Beats. Through the power of the Internet, iterating and improving ideas isn’t just something you do for yourself alone – it’s something you can share with others. That’s the idea behind our own tangible interface hackday coming up on Saturday:

Thanks to Artur Nowak for the tip. I know we have a number of readers in Poland, so is there anyone who could help with a quick translation?

(Oh, and Poland, by the way – my book was actually translated into your language!)
