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.

Moog’s Moogerfoogers, the boutique all-analog hardware effects units, are brilliant piece of sound gear. They’re accessible, terrific sounding, and exquisitely-designed in terms of interface and control. Even as a software person, I just have a lot of respect for the design of these boxes.

I’m sure Moog Music hopes you collect these things (oh, if I had that budget), but if you had to take just one Moogerfooger, the just-announced MF-105M might be your strongest candidate. First, it combines the two previous Moogerfooger MuRFs – that’s the Bob Moog-designed Multiple Resonance Filter Array. The MuRF (rhymes with “Smurf”) is basically eight filters which are sequenced to “animate” the effects in interesting ways. The original MuRF led to a set of bass filters, aimed at bass players or guitar players “looking for a heavier, darker sound.” Previously, you’d have to buy two separate Moogerfoogers to get both; the MF-105M just gives you both in one box.

More importantly, the “M” in the MF-105M stands for MIDI. Modulation is only fun if you have something with which you can modulate. As on the whole Moogerfooger line, you can use Control Voltage, but the MF-105M also uses MIDI, as seen in the demo video below.

• Change from pattern to pattern using MIDI Program Change
• Sync your patterns to tempo with MIDI Clock, so you can play along with a drum machine, Ableton Live, whatever
• Control any front panel with MIDI Control Change messages – for instance, control the envelope with your Mod Wheel
• Play the filters with MIDI notes

It’s still US$479, but you get what would otherwise require two of these units plus a MIDI-to-CV converter. And it’s all set up to use out of the box. It’s definitely a keyboardist and synthesist-friendly Moogerfooger – and for guitarists with MIDI guitars and a lot of imagination.

Thanks to Ben Hovey over at Moog for sending this our way. (And yes, everyone is free to send us your product news, please – can’t guarantee it won’t get lost in my frightening inbox, but…)

Available in August. Video (silly titles, but about halfway through they have some useful demos):

Gestural Music Sequencer from Unearthed Music on Vimeo.

Something as simple as remapping a single knob can give you new musical ideas. So expand that to entire gestures and live video input, and you can help push your performance in new directions and out of old habits. That’s why it’s always great to see projects like the Gestural Music Sequencer.

Built entirely in free tools – tools fairly friendly even to non-coders – the GMS lets composer and musician John Keston explore new ideas through gestures captured in a video stream. It’s easier to see than to talk about, so check out the just-completed documentary short by Josh Klos, with the aid of Julie Kistler and Brian Smith. (And yes, documentation makes a huge difference; we’d love to see more of this stuff!)

The ingredients:

• Processing, the free, multiplatform coding environment [site | cdmu tag | cdmo tag]
• controlP5, a lovely, light, quick-and-dirty library for UI controls
• Ableton Live – though you could substitute other software via MIDI, Live makes a nice, familiar interactive music engine

Lots more information on John Keston’s wonderful Audio Cookbook blog, which is fast becoming one of my favorite reads:

http://audiocookbook.org/category/gms/

And here’s a really lovely video that demonstrates what you can do with video. It uses a string of lights in a jar as the source. Yes, in a way, it’s almost like having a very focused random generator, but I think there’s nothing wrong with that. There’s an almost analog approach to seeing the source, and using that to organically create music.

GMS: Chromatic Currents Part II from Unearthed Music on Vimeo.

I have to observe, while this works reasonably well with MIDI, it reveals why standardizing on networked communication, as OSC does, makes more sense. In a world of software, “controller” can really mean anything you like. Control is increasingly about software talking to software – including when devices are involved, since they generally have a software layer of their own. Also, because sometimes it’s easier to code this with Processing than with Max, I can see some powerful uses of the Python-based Live API, which we expect to mature later this year. (Yes, the project called Live API seems to be in a holding pattern, but we may be able to work up a more complete, Live 8-ready alternative.)

By the way, our goal is to make noisepages a platform and collection of tools for people doing this sort of work (or anything creative with music and motion), even if you host your blog elsewhere. Stay tuned for the details on that.

Fritzcrate Project / lusidLearn Early Demo from Michael Schieben on Vimeo.

Knobs and faders can be rigid. Fancy multitouch devices can be expensive. But for the cost of a webcam and some spare materials, you can build computer interfaces with objects around the house, thanks to the power of open source software.

In just one day, a group of artists in the CDM community, from Austria and Germany to New York to Australia, got quite a lot working with tangible interfaces. At top, Michael Schieben and Christophe Stoll experimented with using soda bottles to control software like Future Audio Workshop’s lovely Circle. (Ableton Live works, too – as does any MIDI software.) As Precious Forever, these guys are responsible for some of the best UIs in music software, from FAW to recent Native Instruments designs, so it’s lovely to see them experimenting with this idea.

As you add more people to the mix, you get ideas you might otherwise never have imagined, from a game involving blocks of the Tokyo skyline to an interface built into floor toms.

We also got a lot of real-world data on what works, what needs work, and what causes trouble for beginners, which we’ll be documenting. (Adam and Martin from the Trackmate and reacTIVision projects, respectively, were both tuned in to see progress and provided lots of help – and are also collecting that data to improve their own documentation and libraries.) More commentary on all these side benefits, as well as a discussion with visitors from Argentina on the scene around the world, at Create Digital Motion.

Musical Resources

We also got some really helpful tips for working with the free, powerful, tri-platform synthesis tool SuperCollider:
Charles Martin wrote up an easy SC test script for receiving Trackmate messages (and also had the clever idea of using a floor tom)

And for connecting Trackmate to MIDI and working with Processing, lots of tips are available on Michael Schieben’s noisepages blog:

Our noisepages community is still in “alpha” state, but it’s usable – we’ve just fixed avatar uploading, which was the biggest problem. We’ll have more features, functionality, and improvements down the line, as well as more extensive documentation for how to get started. But if you’re a bleeding edge sort of person, join up free and give us some advice on what you’d like out of it.

I look forward to more work on these projects. Stay tuned for more, including some additional documentation (I’m developing some stuff around my own project).

“Augmented Reality” is a fancy term for describing ways of using computer vision to overlay digital intelligence on images. In other words, you can, for instance, scratch a vinyl record using a camera – plus a tag for identifying the object’s position in 3D space.

Cambridge-based designer Todd Vanderlin put together an elegant demonstration of the possibilities here, and his video has accordingly been making the rounds. (See: Synthtopia – and I actually heard about it this morning from a high school friend. The power of the Internet.)

Todd has more details on his site, which includes all kind of wonderful projects, like laser sound fountains and, always favorite around here, creepy circuit-bent baby dolls.

AR Scratching [Todd Vanderlin]

There’s actually some work to this: you need to figure out how the album is spinning. And of course, because this is augmented reality and not reality, there’s real potential here to imagine a new kind of vinyl DJing in which normal physics don’t apply.

From the video description:

I was playing around with some AR markers the other day and came up with this idea. taking just a plain old vinyl record and attaching an AR marker to the label you can track the record in 3D space. The next question was, can you scratch the record?

So by figuring out the velocity of the records rotation and applying it to the payback of the audio you can scratch. There is some digital noise that needs to bee worked out, but sounds pretty good. Its still really hard to scratch, it takes some practice but is super fun. The next step is to figure out some nice triggers for different modes. I like the idea of not needing a turntable but the actual spinning of the record helps with the scratching and playback. I made a couple modes, one where the record is paused and you can just scratch through the song. The other looks for zero velocity for x time and then continues on with the song. If there is velocity you then are scratching and the audio is affected. I think that this project has some legs can’t wait to play more.

I Want My Augmented Reality TV

So, this has sufficiently inspired you and you want more augmented reality? We’ve got more for you.

Digital artist and magician Marco Tempest has just demonstrated what happens when you do card tricks with augmented reality – and he shares some details of his rig:

If you’re ready to do this yourself, we have a number of resources:

We’ve also got an in-progress library for use with mapping projections in space for “spatial augmented reality”

Score one for “old school” on the Theremin – minus one for “old school” on the Minimoog keyboard.

There’s plenty of debate about whether or not you can justify splurging on the extra cash for the Moog name on synths and effects – no one questions Moog’s quality, but there is other great boutique gear out there that gets far less attention. But one area where the Moog line is unquestionably superior is on the Theremin. And the Etherwave Plus at US$519 is an instrument you can really sink your musical teeth into over a period of years. With the addition of a Control Voltage output, you can control other instruments and effects, too. (Reader velocipede checked out a demo with Theremin controlling a guitar filter.) CV outs for pitch and volume are separated, so each hand gets isolated control. It’s a lovely setup, and I wouldn’t hesitate to get the Plus version.

Etherwave Plus Theremin [Moog Music]

So, the Theremin gets a little more old school with the Etherwave Plus. But meanwhile, Moog Music has announced they’re building only 200 more units of the Minimoog Voyager Old School model, which we admired at last year’s NAMM. This keyboard added retro wood-paneled styling, but took “old school” literally by eliminating patch memory and MIDI – the very features added to the Voyager that gave it more modern appeal. I expect the Old School may never have been intended for a longer run, but I’m not sure any of our readers will mourn its loss – the response to losing MIDI was a resounding “huh?”, and the Old School still costs US$2595.

Minimoog Voyager Old School

Still, you have to give props to the Old School for having the best slogan ever, even if it was only used internally: “Got Balls?”

How many products dare you to use them based on features they don’t have? (Too bad Moog didn’t use this as the official slogan, suggesting their answer was “Nope.” Well, at least as far as marketing. They’re no Synthi.)

I’d still love to see a Moog product that’s not an effects unit but does bring a little something to bargain-minded synth lovers. Maybe a NanoPhatty?

Across series of colored bars, sounds warp and mutate. Vines entangle as organic threads of music. Fingers and objects traverse sonic landscapes in surprising, mysterious ways. Welcome to the worlds of BricK, the musical table interface by Jordan Hochenbaum and Owen Vallis, which, charged with software by Dimitri Diakopoulos, Jim Murphy, and Memo Akten, explores new musical frontiers. The tool uses a combination of open source tools for tracking fingers and objects on a table, then feeds those into sound and music environments.

Just following the landmark, long-awaited release of Processing 1.0, BricK demonstrates the expressive potential of the open-source platform. Processing allows quick and elegant development of stunning visual interfaces, while other tools (ChucK and Reaktor, for instance) serve as sonic engines. Sometimes the sounds themselves are not revolutionary, but by simply replacing the visuals and interaction – just as with changing the look of a score – the music is transformed, too. (At top: experiments with different interfaces for music using the platform they’ve built.)

CDM got to talk to Owen and Jordan about the projects. And now’s a perfect time – the gorgeous Roots is looking for a home, in case we have any curators / galleries / other interested parties in our audience. First, a review of what these platforms are:

Spaces, Multi-Touch Music

Spaces Multi-Touch Music Environment from BricK Table on Vimeo.

Jordan tells CDM about Spaces, their latest creation, which premiered alongside a performance by Daedelus in LA:

Spaces is the latest interactive multi-touch musical application for the Brick Table. Designed as a minimalist interface to free musicians from traditional compositional markers such as frets and keys, the environment enables musicians to compose intuitively through immediate visual and sonic feedback.

In this video, Spaces mediates a spontaneous composition and performance of a slow-moving ambient soundscape.

Spaces was developed by Jordan Hochenbaum, Owen Vallis, Dimitri Diakopoulos, and Jim Murphy.  It was recently used in a performance at the REDCAT lounge at the Walt Disney Theatre, Los Angeles, and further developments are currently underway.

Roots, an Organic Installation

Roots Multi Touch Tangible Installation Teaser from BricK Table on Vimeo.

Roots has been impressive in Web videos, but it’s looking to make the transition to the real world, after a shipping mishap prevented what was supposed to be its premiere showing at New York’s Minitek Festival earlier this fall:

“Roots” is an interactive installation for the Brick Table tangible and multi-touch interface, where multiple people can collaborate in making music in a dynamic & visually responsive environment.  Users use their fingers and tangible objects to create and interact with virtual branch-like vines that move around the screen, allowing users to create either entirely generative, semi-generative, or sudo-composed arrangements and compositions. 

Roots is truly a unique and expressive interactive installation which came together through an internet collaboration between Brick Table’s creators (Jordan Hochenbaum and Owen Vallis), and the super-talented London-based designer/developer Memo Akten.  It was recently selected as a featured Processing Exhibition on Processing.org and we feel it is time to release Roots into the wild…

So! We are calling out to all of you lovely CDM readers out there to get Roots out and into the public.

For more information on how Roots works, please see What is Roots?

Please use the contact on the BricK Table website if you are interested.

Behind the Scenes

CDM: How do the visuals relate to the sound?

BricK: The nature of the vine-like branches in Roots lends itself to creating music with what is — in our opinion — an organic and open feeling. We felt that the music should both sound and feel as if it is coming out of the visuals, and vice-versa, and so we did our best to stay true to this relationship in the overall musical aesthetic of the sounds produced.

The Spaces environment expands on the theme of unconventional visual representations of sound manipulation. Each column is an open space connecting an idea with a musical parameter. Combined with the visual feedback, we decided Spaces would work best with slow-moving ambient soundscapes, although it is certainly possible to experiment with other musical styles..

What sorts of relationships did you experiment with before settling on something you liked?

BricK: With Roots, we first worked with Memo to develop the visual elements before even attempting the musical side of things.  We discussed various approaches to its visual and musical relationships. Did we want it to be completely generative? Did we want a more direct and repeatable relationship between your finger and the resulting sound?  We really liked both ideas, and so we made it all inclusive– making it able to create completely generative, semi-generative, or directly manipulated/composed musical outcomes by the use of finger pressing, sliding, and tangible object interaction.  This really makes Roots unique in comparison to other environments which enable generative musical arrangements.  Each performer can exert as much or as little control over the relationship between physical, visual, and musical interaction as they want at any given moment.

In Spaces, we discussed a few different ideas about the layout and design of the interface. Ultimately, we decided on Spaces being able to control four different instruments, each with four parameters (volume, and three others). We toyed with different methods for visually representing the value of each column without turning them into a traditional slider. We felt the cool-to-hot color morph in each column was fitting: the user has to rely more specifically on the sonic result rather than exact value, veering from more traditional musical interface paradigms.

How did you deal with timing relative to the visuals?

BricK: In Roots, it was necessary to have the generative data play in a relatively synchronized manner to maintain a degree of musicality. As the vines move around the environment, the musical outcomes are quantized to various beats. [Ed.: The quantization all happens in ChucK.] That being said, continuous finger movement scrubs audio in a direct 1:1 relationship that gives the user the feeling of direct manipulation when that is wanted.

Spaces has no generative movement (at the moment) which means timing is always completely synchronous with finger movement, both sonically and visually. We tried to make sure that the way in which the colors morph feel as free and smooth as the slowly evolving musical outcome.

Can you talk a bit about how the sound is generated?

BricK: Roots uses audio buffers as its underlying sound source (although the musical outcome is VERY different than the original material). Each vine gets assigned an audio buffer which is then ’scrubbed’ through as the vine generatively maneuvers around the screen.  The audio and buffer manipulation is done using the ChucK audio programming language. By simply changing its source material, Roots will produce vastly differing musical results.

Spaces generates sounds in a number of different ways, all using Reaktor. Each of the four instruments employs a selection of synthesis methods. Some columns control pitch, other columns control combinations of filters and effects. The clicky percussive sounds are generated from an audio loop which is granulized and re-synthesized with altered delay rate, etc.

What are your future plans for these pieces?

BricK: Roots is ready to go, but in our free-time, Owen and I play with using it as a sequencing device in other ways — using movement and vine-location to pluck notes, control effects and filters, etc.

Exploring Roots along these other avenues will probably create the need for a new GUI interface, which means perhaps Roots will have a new little cousin sometime in the future.  That being said, we are really happy with Roots as is (we reached our specific goals), and we are more interested in giving it the proper debut it deserves, rather than changing the way it works.  We had a great time working with Memo, whose work I actually first came across here on CDM, and would love to work with him again in the future.

Spaces was developed in a very short timeframe for a performance at the REDCAT Lounge at the Walt Disney Concert Hall in downtown Los Angeles, and so we are absolutely looking to expand the possibility of what the Spaces interface is capable of. First, we would like to expand the number of instruments capable of being performed. Secondly, we would also like the interface to be “physics”-enabled, for example, using a flick motion to send a bouncing ball down a column to automate a parameter as the user concentrates on other instruments.

The Software

Just to review, here’s the software powering BricK:

tbeta (“The Beta”): finger tracking. tbeta is an open-source, cross-platform computer vision and multi-touch sensing platform. It’s the successor to the former touchlib, which wasn’t as cross-platform or quite as awesome. More on tbeta on Create Digital Motion.

reacTIVision: fiducial marker tracking for objects. (Fiducial markers are these funny, cellular-looking patterns pictured at right that allow you to track specific objects manipulated on the table. reacTIVision is the open-source library developed by the folks who did reactable. Sounds as though we might get fiducial tracking in the other library, though.)

ChucK: a strongly-timed, quick-to-code sound and synthesis language. It’s elegant enough that it’s used for real-time programming – as in, onstage, in laptop ensembles like PLOrk and (its West Coast descendent we just saw here on CDM) SLOrk.

Native Instruments Reaktor: The modular sequencer, instrument, and effect builder, which we cover regularly on our Kore minisite. It’s the only commercial / non-open-source choice here, though it may actually replace ChucK on Roots in the future.

Squarely in the “not seen at NAMM” category, the Bubblegum Sequencer uses differently-colored bubble gum balls, arranged in a grid of holes, to create rhythmic patterns. It’s not exactly a leap forward for music — you wind up with a pretty simple drum step sequencer — but it does look like fun. Or it would be, except I’d wind up eating the tangible sequencer. Note to self: make interfaces out of something I won’t devour.

What’s rather interesting here is that the whole system uses computer vision analysis — a camera spots the gum balls by color. One thing that means is that you could skip the grid altogether and apply this to something very different.

The hyper-rational voiceover I find really amusing. Now, just add hard-disk recording next year, and the Bumblegum 5000 could  in fact be at NAMM.

Thanks, Johan!

Updated! Holy crap! Analog Industries has started a blog war:

Peter Kirn got all up in our grill with a bubblegum sequencer over on CDM. Well, Peter. I’ll see your bubblegum sequencer, and raise you one done with Skittles.

“I Eat Beats” Skittle Sequencer

I Eat Beats from Kyle McDonald on Vimeo.

But, come on, Chris. I enjoy my Skittles now and then, but bubble gum is more delicious, and you can’t blow a bubble with a Skittle.

I have heard that Moog Music is introducing a Candy Sequencer OS (Old School), using salt water taffy. And looking at comments, the International Conference on New Interfaces for Musical Expression this year may just turn into a massive rumble / turf war of tangible interfaces. Which is why my tangible interface will be Pop Rocks.

Updated, again! Still more. This time, Evan from thisisnotalabel sees our bubblegum sequencer and raises us a ball bearing sequencer. Careful, though, kids. Those are not edible. Choking hazard!

Still more: it’s a dining table as musical interface, in a sonically-augmented culinary artwork:

Who says progress is bad? Synth designer Dave Smith’s Prophet ‘08 synth is a new instrument inspired by his legendary Prophet series, but there are a number of clues that indicate it’s not 1978. First, driven by Internet buzz, word-of-mouth preorders are already taking off. (DSI hasn’t yet added the Prophet ‘08 to their price list because they’re scrambling to fill the early orders.) That means, ironically, the Web generation is better able to support “boutique” synths now than even synth customers of a few years ago. Second, I expect a lot of these Prophet ’08s will happily become outboard analog gear complimenting computers. (It’s a good thing Dave Smith was a driving force behind MIDI.) Lastly, the Prophet ‘08 has some great features we take for granted now that were harder to come by in 1978.

The Prophet ‘08 is analog to the core: it boasts a 100%-analog signal path and a “sonic character” not surprisingly modeled on the classic Prophets. What’s new:

• Velocity and aftertouch: If this spoils the “vintage” experience for you, go see a doctor.)
• Mo Modulation: “Extensive modulation routing capabilities”, making the Prophet ‘08 essentially a semi-modular synth; it’ll be interesting to see what this lets programmers cook up.
• Splits and layers:Four-on-four splits and layers with separate stereo outputs for each layer.
  
• Arpeggiator and sequencer: Arpeggiator, gated 16 x 4 step sequencer, and LFOs. Everything is syncable, as well — thank you, MIDI.

There’s onboard MIDI (even with “Poly Chain”), and CV input, as well. On the analog side, you get 2 oscillators and 1 lovely filter per voice:

• 2 digitally controlled analog oscillators (DCOs) per voice with selectable sawtooth, triangle, saw/triangle mix, and pulse waves (with pulse-width modulation), and hard sync.
• White noise generator

I have heard some complaints about the new models: some would prefer the pitch and mod wheels next to the keyboard rather than above, though the payoff is a full five-octave keyboard in a compact space.

I have to say, I’m a sucker for the Dave Smith philosophy of “un-nostalgic” analog. But, really, who would expect anything else: Dave Smith’s earlier instruments all progressed with technology, and he continues to do so. There’s a clear resonance with the modern Moog synths, like Minimoog Voyager and Little Phatty, down to special editions with colored wheels. (Dave Smith has the much cooler red glowing wheels, which is great if you’re tired of blue.) But the Dave Smith Instruments are also unique takes on how to reinterpret analog.

Detailed specs and descriptions are on the mercifully redesigned Dave Smith site:
