For the lover of musical instruments and technology, southern California’s NAMM show is a giant toy shop. It’s work for many of its attendees, of course, but we know many of our readers dream of the objects that will make their next creations. And sure, inspiring lust is not our aim; on the contrary, there is some love that goes into these things. In the ideal, that’s the relationship of creator and consumer. These are things not to be bought and discarded, but kept and really used.

So, we have a different look at the NAMM show, through the lens of CDM contributor Marsha Vdovin, who has been at this show more times than she might like to count. I’ve added some comments about what these devices are and why they’re important. And the next time we see them, these inventions pictured in silence here, we expect them to be working hard on music far from the din and flourescent glare of the trade show floor.

As always, click for larger images. Photos by Marsha Vdovin; words by Peter Kirn:

Roland’s V-Guitar marks a surprising collaboration, bringing the famed American guitar maker Fender together with the Japanese electronic maker to make an “electronic guitar,” merging the two company’s tech on a digitally-augmented Stratocaster. More on this soon – but the extended playing techniques won over many guitarists.

The Danish design aesthetes of AIAIAI have improved upon their TMA-1 headphones with a studio model. Same drivers, same basic design, but a “flatter” response to sound (rather than beefed-up, DJ-ready bass) and closed ear design. It’s impossible to hear anything at NAMM, but I can attest that the new design is far, far more comfy to wear. Actually, if I could have kept these on the whole show to drown out the sound, it would have been great.

An easy place to spot a talented celebrity was at the Dave Smith Instruments booth, at which artists clustered around Dave and Roger Linn. They were on-hand with plenty of tweaks to their stellar Tempest drum machine.

Teenage Engineering’s OP-1 grew up, with new features (drum sounds! MIDI sync – at last), and grew out, with a companion product for connecting sensors and USB host mode that could be a boutique item for music DIYers. We’ll go hands-on with each this year, and while readers were disappointed on a lack of some details (will the OpLab be open source?), we expect to get more details from the Teenagers when the product is ready in the coming months.

Readers of tech blogs (ahem) may miss out on the fact that the vast majority of NAMM is really for guitarists, drummers, and traditional instrumentalists. And yes, that includes glittery, pink products from Daisy Rock Guitars. We’ve concluded this model will be perfect for Sparkle Pony. (And really, if you’re not watching Portlandia to get that reference, get on it. Also, Jenny Conlee is crazy awesome.)

Thin, responsive, and expressive, the QuNeo from Keith McMillen – funded on Kickstarter – proves it’s really happening. With continuous pressure response on its touch controls and bi-directional control, it could be the most anyone will ever have gotten from a US$200 controller. Yes, we’ll be watching.

Pioneer wasn’t showing anything new at this show — they timed those launches over the fall with new controllers like the Ergo. But they did have a glossly all-white lacquer set of limited-edition devices that looked absurdly gorgeous. Now if I want to do my flat over in the style of a Stanley Kubrick set, I know what DJ gear I’ll be buying. (If you don’t know what I mean, watch the end of 2001 again – or the living room in Tron: Legacy, which is more or less a copy.) White is the new generic-dull-charcoal.

Akai’s MPC Renaissance is unlike any other mass-market controller we’ve seen. It’s actually substantial, something that feels like a vintage MPC even though it’s designed to work with software (pictured). The audio circuitry is straight out of the modern MPC, but there’s a switch for “vintage” modes – think 12-bit output when the MPC60 is enabled, for instance. Akai told CDM they built the software in-house, but we also learned at NAMM that they licensed time-stretch tech from iZotope, giving their upcoming MPC software generous audio-manipulation abilities.

The Renaissance will cost you, with a street expected well over a grand, but that makes it even more welcome that the same superb pads and response curves are also on the maker’s MAX49 keyboard and cheaper MPC Model.

Just expect to wait: these were prototypes, and there were still some bugs to work out.

The Renaissance is for the MPC die-hard; the MPC Studio is the model that will directly take on Native Instruments and Maschine. It’s slim, sleek, and still has great-feeling controls. And while that makes it compelling competition for Maschine, I’m gratified to see this whole market expanding, new workflows for performance and production, and a push to better quality in the controllers. The days when computer gear meant “cheap and plastic-y” are mercifully at an end. Speaking of which –

Akai’s MAX49 keyboard could be a new model to beat. The keyboard action is satisfyingly springy, with a new keybed not seen in previous models. The pads are identical to those on the Renaissance, and feel more the way proper MPC pads should. Not everyone will love the light-up, touch-sensitive resistive faders, but I found with a bit of pressure, they worked well – and that means never having to worry about a fader catching up with the value in software. You also get serious features: Control Voltage, a full complement of MIDI ports, and aftertouch. Did I mention Control Voltage? It’s nice to see a controller keyboard with a slightly premium price, build, and features.

The last surprise from Akai was this MPC DJ. The company says it’s a prototype only, and had little more to say about it, but it’s fascinating to see the MPC and turntable controls converge.

Moog’s Minitaur was my favorite synth of the show. It just sounds consistently brilliant, no matter which way you turn it or play it – and I accordingly noticed it was the synth the most people were actually playing on the show floor.

This is what a 24-karet KORG MonoTribe looks like, alongside a silver-plated model. There’s little more one can say. It is, of course, one of a kind — and already spoken for.

The other thing of beauty at the KORG booth: a limited-edition reverse-key SV-1 keyboard.

iOS accessories were numerous, but a few were genuinely useful. IK Multimedia’s iRig Mic “Cast,” for instance, is coupled with handy software for podcasters, as a quick tool for interviewing or podcast recording.

It’s not a new product, but one of the reviews to which I’m most looking forward is this Eers product. It promises custom in-ears you make yourself, rather than the enormous cost of getting them custom-made. Stay tuned on this one – protecting your hearing and making on-stage gigs go well is perhaps as essential as gear can get.

The just-intonation Hymnatron from the Dewanatron crew was one of the most compositionally-compelling instruments at the show, with a unique sound, tuning, and key layout. And it looks mighty handsome in this one-off wooden case.

LiveWire’s modular was among the many dreamy modular rigs at Big City Music and Analog Haven, two Los Angeles hotspots for analog modulars. Did we mention space was more plentiful and inexpensive, and gigs more generous, in LA than in NYC, Chicago, or San Francisco? Funny coincidence, that.

Many modules graced this show, but the most intriguing was not analog, but digital – think digital algorithms in an analog, patch-cord-modular hardware workflow. Tom Erbe, maker of long-beloved SoundHack (the app, and then more recently the plug-ins) put some of his sonic wizardry into a module, collaborating with one of our favorite modular builders, MakeNoise. The result: the MakeNoise Echofon. As such, it’s a perfect emblem of our Create Digital Music, Create Analog Music philosophy. Dear Berlin friends: let’s plug this into your monster modulars, okay?

Big City Music is a wonderful place. The other candidate for best new module: brilliant creations by Metasonix, as previewed here. We’ll be watching for these to be patch-able, too.

Casio had its classic CZ-1000 synth on-hand at its booth. The Casio XW isn’t quite a successor to the CZ, though it does include some of those waveforms and phase distortion sounds. What it does appear to be is a very affordable, do-just-about-everything workstation at a fraction of the price of any of its rivals. For someone who wants a jack-of-all-trades gigging keyboard, this could very much be a contender.

Our friends at Beatport are evidently getting into the hardware business. The most interesting launch wasn’t a set of TMA headphones with Slimer-green cords (I’ll take the Studio model, thanks, or just a non-Danish set of studio cans). Instead, I was intrigued by the eminently-practical line of gigging cords Beatport is working on with Hosa. They include features live digital musicians and DJs badly need, like color-coded cords you can find easily at a show, and hinged USB cords you can cram into tight spaces. More on those soon.

Thanks, all. Lastly, I want to thank everyone I got to spend time with at the NAMM show, and particularly Marsha Vdovin, who is responsible for these photos and keeping our schedule together. NAMM is always too crowded and too short, but it can lay groundwork for a whole year. And I’m excited for this Year of the Dragon. Be seeing you.

Sound and light artist, guitarist, Max patcher, and all-around sonically-fascinating guy Christopher Willits has opened up his “Tiger Flower Circle Sun” record on Ghostly to remixing. Halfway through the project, we talk to Chris about what’s going on – and what the results so far sound like. And we share, from earlier this fall, a composition in which you can recharge.

The project begins not with stems, but with samples, the raw materials on which the album was based. Christopher walks CDM through the audio highlights, one sample at a time. Along the way – as with all these samples – you begin to appreciate the process by which Christopher makes his decisions, how he moves from samples like pieces of wood to the finished structure. And of course, by opening these up to remixing, you have an opportunity to hear the work differently in his finished, released form, as well as to find your own, distinct decision-making process. It’s perhaps obvious in a remix project, but what this does is to allow the sounds a life separate from the fixed set of decisions that produced the album.

And that can even change Christopher’s own view of the work, he says. He tells us:

I think it’s fun to play the set like an album. I’ve heard these pieces so many times that it’s really refreshing to me to hear them alone. Now I hear the pieces differently.

That was actually one of the thoughts behind sharing all of these sounds, so people can hear the layers, and if they wish, tune their ears to the subtleties and intention I wanted to create in the mixes.

You can find the remix project at:
http://willits-sample-library-vol1.herokuapp.com/

“The stuff i’ve heard so far is AMAZING,” Christopher tells us. “I can’t wait to feature the best of the best. We’ll be releasing a free comp on [Christopher's experimetal label] Overlap and Ghostly will feature my favorite remix on a free comp, too.” Winning remixes get Ableton and SoundCloud prizes.

Let’s hear a few words from Christopher about the sounds he’s produced.

A Tour of the Sounds

A lot of the samples are about variation of common materials, so there’s plenty to explore. Christopher tells us that just one sample – like this guitar solo – can take on very different meanings with different processing, heard in two variations.

Guitar process solo2-Sun Body-Willits-120 by Willits

This tone is created from a custom-made Big Muff > BOSS distortion > Fender Twin with a couple power tubes removed for low volume and max distortion. This is a trick that ted from Flipper showed me around that time, and it created the exact orange laser beam i was hearing in my imagination.

Guitar solo long noise-Sun Body-Willits-120 by Willits

Guitar solo-Plant Body-Willits-120 by Willits

The whole piece “Plant Body” came from this guitar improvisation. With releases like “Folding and the Tea” and “Seven Machines for Summer,”

I set the process to be only the guitar recordings. With this release, I gave myself a new set of constraints and permissions, allowing my imagination to add whatever comes up for me. No judgement on which one is better to me, they are just different. There are infinite possibilities within any process I determine, yet discerning the process that resonates with my true intention is what creates the shapes and forms and colors that feel like love.

The drum samples come from:

…my great friend Jeff Pierre – one of the best drummer I’ve ever worked with, and the youngest, as well. All of Jeff’s takes were one take; this sample is shortened from the original length, but you get the idea.

Someone please make a disco track out of this.

Me and my friend Reiko were messing with patterns; then we would find a loop. We were laughing so hard as we were playing this stuff.

Perc-Intend-Evolve-Willits-120 by Willits

Check your volume for this one — probably should have exported it at a lower volume for this set! The heat of this, the crushed distortion, is from a technique called input flipping on the SSL. This is an input flip with the preamps cranked, with odd harmonics.

Ryan (Ryan Kleeman) and I just about lost it when we first input flipped like this for a distorted sound. It became a theme in a sense that resonated with this orange laser beam electromagnetic sound that much of the work stems from.

Synth arp noise-The Heart Connects To The Head-Willits-120 by Willits

You can also hear it here- and a few other places on the record, to a less extreme degree. There is something about this texture that has a cleaning function to me. Washes things off, away, cleans the ears out. Resets your space.

Branches Into Flowers-Willits by Willits

“Could hear many more strings and horns in this piece.”

“Love this kind of generative sound.”
Subconscious Transmission-Willits-120 by Willits

Two samples that were not used in “Light into Branches.” Made the baritone thing in one mode of listening, came back and asked myself, why did I put a baritone guitar solo in the middle of this song? Did I really think that’s what it needed, or did I just want to play my baritone along with this song for fun? The answer was the latter. But here it is anyway.

The ambient layers sample was to create more depth of field in the mix, have it floating behind at a low volume, but it was not doing was I wanted it to, so I cut it out.

Soak in a Sound Bath

Another release from this year revealing Willits’ musical approach, “GOLD” is an ambient piece in you can inhabit, in which you can restore yourself, according to its maker:

GOLD is a 24 minute and 17 second sound bath / ambient piece to soak into. Listen, relax and recharge. This harmonic weaving of sound was created with the vibration of affinity, love.

Made with voice, processed guitar, and a low-frequency oscillation out of a Nord Lead synth, Christopher actually encourages people to share how they “used’ the piece and how they made it felt, a kind of design experiment for spiritual being in sound. Have a listen or pay-what-you-will on Bandcamp:

Read up on what he has to say about this release:
New Release – GOLD [Sound + Light - Chris' blog]

Infinite

It seems only appropriate to close with this reflection from Christopher:

After working on this project, I’m realizing so tangibly what I’ve always known — that any mix is a sonic photograph of vibrational affinity, and even with a grounded intention behind any mix, and a very clear outline for a process in which you allow that intention to emerge, there are infinite possibilities of expression. Infinite. It is so beautiful.

What do you do if you can’t find an instrument that you can play the way you want? In the digital domain, you can just invent one.

So, when Brooklyn-based artist Nick Demopoulos wanted a controller that’d allow him to articulate digital instruments more like a guitar and less like a keyboard, he built his own expressive touch controller. It uses arrays of touch-sensing strips on a guitar body. A future version, he says, will incorporate 6 “strings” (touch strips).

New York-based literary/culture quarterly BOMB Magazine shot a video in which Nick walks through his creation.

Nick has also played our Handmade Music series in New York, at Culturefix. (See documentation of that event, from 2010.)

Videos of Nick playing:
http://www.youtube.com/user/nicnut210?feature=mhee

Lots of stuff on SoundCloud, too; I enjoy the rhythms in this one:

Whispers in the Water by Nick Demopoulos

http://soundcloud.com/nickdemopoulos

It occurs to me looking at this, too, that if you could improve the sensing accuracy and physical feedback from the touch strip, you could radically improve the instrument. It’s really the quality of these kinds of sensors that will have the biggest impact on future instruments – that is, the fundamental ideas about these controllers are out there, and now implementation means everything.

Thanks for sharing your work, Nick!

Gibson Guitar has announced in a press release they’re acquiring the Stanton Group, which includes, aside from the well-known Stanton DJ brand, KRK monitoring products and Cerwin-Vega loudspeakers.

It’d be easy to see this as a guitar company buying a DJ company, but it’s more than that. KRK and Cerwin-Vega are speaker/monitoring brands. Stanton and Cerwin-Vega each have footholds in the larger consumer arena, not just the pro world, a detail Gibson is quick to emphasize. And Gibson themselves have quietly, steadily grown beyond just guitars. The new “Gibson Pro Audio” banner is added to a list of brands that Gibson reels off: “Epiphone, Dobro, Kramer, Steinberger, Tobias, Echoplex, Electar, Flatiron, Slingerland, Valley Arts, Maestro, Oberheim, Baldwin, Sunshine Piano, Take Anywhere Technology, J&C Fischer, Chickering, Hamilton, Wurlitzer.” But it would seem dropping the “Guitar” from the name would be realistic.

There are two interesting details to the way the press release is worded. First, the lead is that Gibson’s move is “part of its continued expansion as a lifestyle brand.” That’s perhaps going to send a chill down the spine of anyone who prefers to focus explicitly on “musicians.” Gibson CEO Henry Juszkiewicz even says the move “allows us access to 20 in 20 consumers instead of the one in 20 we currently hit.” That contrasts with the emphasis of, say, organizations like NAMM who talk about the general market of “musicians,” not only “lifestyle,” whatever you take that to mean. On the other hand, this is really nomenclature we’re talking here; the question I have is how “lifestyle” actually translates into a strategy, and how well it works for Gibson.

The other detail is more interesting. Gibson and Stanton Group reps each stress the potential for overlapping R&D. Juszkiewicz has touted R&D projects in the past, though largely centered around new guitar tech. We’ll see if the two companies can deliver on that R&D promise and do something really innovative. I have no idea what that’d mean in this case, so if anyone cares to speculate, I’m all ears.

Anyone?

Gibson Guitar Acquires Market-Leading Pro Audio Companies KRK, Cerwin-Vega!, and Stanton [PR Newswire]

Online chatter has in past not been very kind to Gibson on its past acquisition record, so I expect some people will raise the spectre of at least one acquisition again. Let’s see… comments…

I don’t personally view this as flame-bait; Gibson’s a perfectly-respectable guitar maker and I imagine there could be some smart business opportunity here, especially with Stanton together with Gibson in Nashville. However, let’s consider: the names Gibson and Stanton, guitars and DJing. I imagine some flame-broiled comment thread on the Internet somewhere.

And yes, reasons to be skeptical:

Promises of this sort of R&D synergy could easily fail to materialize. And whether Gibson can manage these essentially unrelated businesses is an enormous question mark. There aren’t a whole lot of acquisition success stories in this business.

From behind the long-gone, so-called “iron curtain,” nearly-lost musical innovation is beginning to become available. But perhaps more than any geo-political change, the power of an Internet-based community hungry to share knowledge is making national borders that once isolated information melt away.

Earlier this week, I shared reflections I wrote up for Amsterdam’s STEIM on the significant of DIY Music. But one group of artists, the Standuino team from Brno, Czech Republic, really exemplified that spirit. First off, their hardware is utterly brilliant and eminently practical, an Arduino-based platform on which they’ve made it easy to create and modify designs, and share useful tools like the sampler they demonstrated for us in Amsterdam. Secondly, they’re international – the performance brought together a Brazilian, Czech, and Dutch artist in their presentation. Third, they took “DIY” straight to the transportation, hitchhiking all the way from Brno to Amsterdam to be part of our performance, for which we’re all incredibly grateful!

The Standuino crew emphasize that they also wish to make the innovation of the Czech people more visible to the rest of the world. You know Bob Moog or Morton Subotnick, for instance, but do you know the name Standa Filip?

You should. The maker of extensive DIY instruments, interactive work, robotic installations, and new media, Standa (hence Standuino) is inspiring a new generation of artists – first in the Czech Republic, eventually in the world. Those artists, led by Standuino, are recreating some of his work, as well as making new work that carries on his spirit.

Check out the videos here to see him talk about his history and play his instruments, then learn more – and find the Arduino-based hardware designs, which I’ll cover more next week – at the Standuino site:

http://www.standuino.eu/

But there you go – from Rio to Singapore, once I hit publish, just about anybody can learn what it was like to be a lone DIYer in Communist Czechoslovakia – then go find open source ideas with which they can make music from the new generation of creators in the Czech Republic, in a matter of seconds.

Yeah, we overhype the Internet. But that’s pretty damned awesome. I’m going out in the sunshine now for a bit, because that’s awesome, too, but I’m pretty happy that I get to make this my day job. And thanks to you for making that possible, because with you as a reader, none of this would be true.

It’s small, but I think it’ll be pretty huge. We’ve seen plenty of guitar audio interface adapters out there. Here’s the dirty little secret: they’re pretty awful. Because they connect to the audio jack of the iPhone or iPad, there are issues with impedance matching and noise / signal-to-noise. (Read: they don’t sound great. I’ve tried them, and since they all use the same in/out jack, they all sound more or less the same.)

The Mobile In from Line 6 has three things going for it. First, it works with Line 6′s POD effects and guitar amp modeling, which is already popular with guitarists. Second, the app that it works with the audio interface is free. No paid app, no add-on fee for presets – you buy the hardware and get all of the software for free.

Third, and most importantly, the Mobile In connects to the proprietary Apple 30-pin connector, so you get digital audio I/O rather than relying on the jack. That means the quality of the Mobile In is, well, the quality of the Mobile In. Without a test unit, it’s impossible to say for sure, but Line 6 at least claims a 110 dB dynamic range on the guitar input and a 98 dB range on the stereo line input. There’s up to 24-bit/48 kHz support, but I’m happy just to get a portable device with line and guitar ins. They’ve even tossed in a 6-foot guitar cable. Total price: US$79.

The Mobile POD app, while free, is no slouch, either: you get 10,000 presets, a built-in tuner, 64 amps and effects and more, even with a neat iTunes play-along mode. And it’s free for everyone, whether or not you have the hardware. And if you want to use a different mobile app, of course, you can do that, too, if you do use the hardware.

With specs like that, this looks like a must-have for the iPhone and iPad, even if you use them exclusively for practicing guitar. Now, I just wish the beautiful New Signal Process accessories, which turn iOS gadgets into stompboxes, had a MIDI-only version. Maybe there’s a MIDI-compatible controller that could eventually be compatible with these. (Line 6, you listening?)

There’s only one catch. Stereo line in. Guitar in. There’s something missing here – output. That means that the Camera Connection Kit with a USB audio interface could be a better option if you have an iPad. You’re still limited by the headphone output jack here – no other output is available. That makes this fine for practice, but people wanting more flexible ins and outs (well, outs period, beyond the headphone connection) will want to consider a USB audio interface. (Of course, the free app is still cool.)

My other wish? It’d be nice to see the Android platform compete with, well, any of this. Theoretically, there may be a way to do digital audio I/O on that platform, too; sounds like a research question. We’ll see if, Android or otherwise, another tablet/mobile platform starts to evolve these sort of features.

Any mobile guitarists who want to test this out for CDM, and share your music in the process? Let us know.

We focus primarily on new machines and technology that make music directly, but of course, these tools make instruments that make music, too. Having seen an image of a guitar string vibrating from German firm Plek A+D Gitarrentechnologie earlier this week, reader Brian Turley observes that the work that company is doing is impressive.

We’re not necessarily talking mass-manufactured, machine-made guitars, either. The device in this case augments more traditional techniques, and can be put in the hands of an expert luthier. Plek’s technique scans guitar necks in multiple dimensions, creates a virtual fretboard in which you can adjust frets, then cuts some combination of frets, nut, and saddle for the desired result. The upshot of all of this: if the frets are adjusted precisely, it’s easier to play notes and string action is least likely to impede intonation. (It plays better and sounds better, done right.)

Here’s a bit on the technique:

The computer ascertains a 3-D like graph of the fretboard surface, including the position and height of the strings. Thanks to the plek scan the relief of the neck created by the string tension is taken into account while calculating the process parameters.

In the Virtual Fret Dress menu the operator can not only determine how much needs to be cut off from each fret but can also set the fretboard radius and amount of fall-off suited for the instrument or player. You can see the height of each fret, how high each fret will be after processing as well as where fretboard buzz occurs because of frets being too high or too low.

More information:
Plek: Technology

Guitar makers and repair shops then buy these machines for their own use; it’s just one tool in a larger toolchain, and it needs a very skilled operator. Humans, therefore, are no less a part of the equation.

I’m of course way out of my depth here; I think the last time I made a guitar it involved rubber bands and a cardboard box in school. But I’d be fascinated to hear from someone working with these machines. And even for us lay people, it’s a small but fascinating window into the sorts of tools now available to luthiers.

Full disclosure: I love waves. Analog, digital, acoustic, we’re talking vibrations in sound (and other substances, as well — and light). I don’t think you get into this area without having a certain wave addiction. If you love waves, you could easily get lost in exploring videos of vibrating guitar strings and pondering the physics of the string.

This story begins not with how guitar strings actually vibrate, but a curious phenomenon when combining the regular oscillation of the string with the rolling shutter of a CMOS digital camera — namely, the iPhone’s. To accurately capture motion, you need to record an image all at once (or at least come close). Rolling shutter or line scan as exhibited in a CMOS camera sensor like the iPhone is a side effect of the capture being scanned from top to bottom, so the bottom portion of the image is saved later than the top. That causes motion to skew across the image. (Long before digital, people played around with the same effect in analog video and even using film photography – all you need is something moving and a way of capturing the image that moves gradually in a different direction.)

When the regular oscillation of the scanning combines with the oscillation of what you’re filming – as with a vibrating guitar string, or the rotating propeller on an airplane — the two frequencies effectively phase, causing some curious distortion. In the case of the guitar, this means seeing the appearance of standing waves that, while they can occur in nature, don’t occur on any conventional guitar. (You can also think of the basic effect as aliasing, as seen optically when video shutters capture the frequency of rotation of a rotating car wheel in such a way that it appears to move backwards.)

As with many concepts in physics, it’s all easier to see than explain, so I’ll turn it over to some terrific videos. I’ve contrasted two at the top of the story; here are more examples.

Below, a high-speed camera operating at 600 and 1200 frames per second, played back 20x and 40x, respectively, slower than you’d see with your naked eye.

And here’s another example of how that might appear on a camera like the iPhone:

Of course, that means – fodder for our sister site Create Digital Motion – potential for more creative abuse, beyond the mere novelty.

What’s also amusing is the heated discussion this triggered as the iPhone video went viral. Read some angry comments – and some solid science among them — at Reddit:
Guitar string oscillations captured on video [reddit.com]

I’m glad people don’t behave (yet) in person the way they do on the Internet.

In person: “Excuse me; I think your fly is open.”

On the Internet: “That guy’s fly is open. He doesn’t even know his fly is open. That’s bullshit. I mean, what kind of person leaves their pants just *(&$#ing open like that? Look, look, look at his open fly. I’m never talking to him again. I’m not even going to wear pants from now on.”

(Seriously, happily, many of the comments are perfectly polite and well-informed!)

School’s out for just about everyone, but I’m going to remember to file this away for the next time I have to explain sound vibration. Now, back to the beach, or wherever you’re relaxing.

Thanks to Alexander Chen, from whom I lifted this via Google+. (See his own work on CDM here and here. Alex is just the kind of person I want to see this, as he’s been working with the aesthetics of vibrating strings! So, hurrah, Google+…

Science and art alike demand inquisitive exploration and experimentation. So, it’s encouraging that a discussion of the future of the digital guitar here on CDM brings impassioned reader debate. There’s some consensus if you dig through our comments: guitarists are compelled by adventures in new technology, and there’s widespread hope that new tech could expand guitar technique and expression, rather than (as the “Auto-Tune” name has unfortunately come to mean) a replacement for musicianship. And yes, there’s excitement about what Antares is doing – just as it’s possible to go beyond the status quo applications of their vocal tech.

But wait — there’s more.

Reflections on conservatism and guitar tech adoption Rich of Way Music sends over an extended, thoughtful rant, inspired by the discussion and directed at his fellow guitarists:
Amongst the guitar players: conservative fetishization and its discontents ;^) [Way Music]

The payoff of guitar research: Adrian Freed of the University of California Berkeley’s CNMAT research center reminds us that the research work with Gibson continues – and fruits of that research appear in products:

Thanks Peter for the mention of our work at CNMAT, UC Berkeley.
Our interactions with Gibson are ongoing and we continue to appreciate their commitment to innovation.
I am regularly confused by the lens used to talk about our research work, i.e., “Where is the product? Where are the adopters?” Good research rarely results in particular products although products are sometimes good demonstration vehicles for new ideas. Our work (as with much of UC Berkeley’s research) is more likely to sneak up on you over decades as an enabling part of the infrastructure, e.g. the first audio plugin, OSC (used in TUIO), pressure-sensing multitouch (next gen. Kindle?), Ethernet EVB, RISC (in ARM), BSD UNIX (part of OS/X), RAID etc. Watch out for how our work at the PARLAB will enable multicore efficiency for audio and music applications. There are lots of acronyms becoming part of mainstream tools already in that project….

I was going to start hyperlinking those acronyms, but I’m afraid you’ll have to Google them.

Why digital guitars matter: The Auto-Tune teaser brought about concerns about automatic intonation. (I do hear from guitarists that they’re really fond of the new automatically-tuning Gibson “robot” guitar!)

But there’s another side to the ability to track guitar pitch, and that’s the ability to combine the guitar with the sonic powers of the computer. Keyboardists have had the lion’s share of the fun over the years with software synths; just as wind, breath, and vocal controllers open up new possibilities, so, too, do MIDI guitars. While possible with any guitar that can send control, Starr Labs have posted some intriguing demos to their blog; see top and below. (I talked about Starr back in January as they introduced new controllers and guitars.)

And yes, you can play the digital guitar and still win a best beard contest with your more folk-oriented colleagues.

I really enjoy the Ztar guitar playing techniques. I’d love to see this in action in a performance, so readers – whatever make of MIDI guitar you may be using – do send those in.

I’m not as concerned about the conservatism, real or perceived, of any one artist. I’ll say this: regardless of the instrument, there’s vast untapped potential in new instruments and controllers waiting for brave artists to try to tap. And all of this can still draw upon knowledge and skill in traditional instruments. With a few thousand years of instrumental history at our backs, I’d say there’s no rush.

We just need a better term than “alternative controllers” or “controllerism.”

Maybe … music?

A new tool could be for the expressive, not just the lazy. That’s the read of Auto-Tune for guitar, and it makes me excited to see what people will do with it. It could be the advent of the true digital guitar.

Antares teased their efforts to bring Auto-Tune technology to guitars earlier this month, having gotten as far as working proof-of concept. (See Harmony Central’s exclusive video above, and Axetopia, Synthtopia.) I hadn’t worked out anything intelligent to say about it, perhaps because I was cowering in a corner in fear.

As a technologist, I have great respect for what Antares does, and their portfolio goes far beyond just the flagship vocal pitch correction. But suffice to say, Auto-Tune has been used in recording in some pretty unpleasant ways – the fault of the user, not the software, I’d argue. It’s regularly applied in order to suck the life out of great, perfectly-tuned singers, as well as to cover for people who can’t really sing, to the point that producers seem to not understand what the sound of a human voice is in all its complexity. (Case in point: Glee. The talented cast sounds incredible live and onstage, and like they have android stand-ins when they’re on the show. In fact, if you disagree with those uses, please – go use some of Antares’ terrific software for good, not evil, and I’ll write about it.)

Auto-Tune as a name, then, has come to symbolize a revolution, an extraordinary blockbuster of software – and the butt of a joke. So, it’s hard not to see a product called “Auto-Tune for Guitar” and carry some of that bias. Sometimes, as writers we actually need our readers to add some perspective.

Auto-Tune for Guitars could likewise be misused to smooth out some of the guitar’s natural intonation subtleties, though I think the danger is far less so than it is with the voice. But it’s more than that.

Reader Jesse Engel reflects on what it could mean. He notes that the significant advance is building the intelligence into the guitar, not just the computer, and that applications could be varied:

Don’t know if you saw this, but Antares has taken a fresh swipe at HEX guitar, putting a processor in the guitar and using it to do some more modern (Auto-Tune, emulation, etc.) processing. [Ed.: Hex refers to the practice of adding individual pick-ups to each of six strings. -PK]

The hex has been around for a while, but it’s a big deal to use it in this way for guitarists since you don’t need to try to do any polyphonic pitch recognition. Literally direct note access. Also, signals add nonlinearly, so effecting each string individually has a different sound than doing emulation on the mix.

The tech looks like it will help a lot of people fake being better than they are (especially bending to the right note), at the expense of the beautiful imperfections of great playing, but the potential of using hex pickups in these new ways is fun to think about.

The digital guitar has been a vision for a long time, from working out MIDI output to multichannel output. Gibson has been the name behind many of those efforts. Back in January 2004, Wired ran a glowing portrait of Gibson’s efforts in print:

The 100-Megabit Guitar: Gibson’s maverick CEO wants to shove Ethernet up your ax and rock the music world. [Wired 12.1]

It’s worth reading the whole article; the technical limitations of the Gibson system immediately come to light. Suffice to say, that vision never quite came to fruition; Wired even this year claimed that the project had been killed – at least at Gibson. None other than Adrian Freed, OpenSoundControl and alternative instrument design guru at the University of California Berkeley’s CNMAT research center, led the group – he, his colleagues, and his many students go right on innovating with or without Gibson. Updated: I’m not able to find the reference for that story, which I read in print. See comments for commentary by Adrian Freed, who sees otherwise.

At the time, CEO Henry Juszkiewicz, oddly speaking in the third person, pronounced, “Progress will happen. If Henry Juszkiewicz didn’t build a digital guitar, I can assure you the digital guitar would still happen.” That prediction may prove prescient.

The 2007 video below shows the debut of Gibson’s HD.6x-Pro Digital Les Paul – working with individual strings. I also saw a demo with Gibson, Intel, and Cakewalk that used each string in a surround speaker diffusion. It was a psychedelic effect, if not necessarily the most practical demo, but proof that a technology like this could have many uses.

For their part, here’s how Antares describes their technology. Notice that they aren’t only talking intonation, but other applications, as well.

Incorporating our world-renowned Auto-Tune pitch detection and manipulation along with our proprietary modeling technologies, ATG-6 is an entirely DSP-based suite of functions that offer everything you’ve always wanted from a guitar, along with capabilities you never imagined possible. From flawless intonation to astonishing tonal flexibility to alternate tunings that open up entirely new areas of inspiration and creativity, ATG-6 technology seriously expands the flexibility and range of the electric guitar while letting you continue to play your own way.

… Using our new Solid-Tune™ Intonation system, an ATG-6 equipped guitar constantly monitors the precise pitch of each individual string and makes any corrections necessary to ensure that every note of every chord and riff is always in tune, regardless of variables like finger position or pressure or physical limitations of the instrument. As a result, listening to a guitar with Solid-Tune is a revelation, offering a purity of intonation that has simply never before been possible.

Of course, Solid-Tune is smart enough to know when you want to manipulate pitch, so you can play bends and vibrato exactly as you always do. In fact, Solid-Tune Intonation makes it even easier to bend to the right pitch every time.

Updated: Chris Randall chides me on Twitter (and I agree) for not mentioning Roland, specifically — that’s the reference above in Jesse’s from-the-hips comments to “hex” guitar. Roland has built a whole business around products that track notes played on a guitar, adding polyphonic pitch shifters, open tunings, note-by-note replacement, MIDI output, and even DSP effects processing. The difference in the Roland offering is that Roland has done all this work in a separate processing box you connect to their pick-up; Antares appears to be promising something that’s all-in-one in the guitar. And the analysis Antares is doing may well prove more sophisticated than what we’ve seen in the past in terms of distinguishing, say, a bend from different notes. That could open up additional and radically-new expressive possibilities, even if the underlying fundamental concept is more or less the same.

On the other hand, the other difference with the Roland offering relative to both Gibson’s past attempts and Antares’ upcoming ones: Roland successfully shipped and sold theirs. Until Antares does the same, advantage: Roland. We’ll be watching.
