slicedbread, on behalf of The Covert Operators, has released a free Windows utility that generates “endless harmonic oscillators” for Ableton Live’s Simpler and Sampler instruments. (Since this was a released, a Mac build has been made available, as well; see link below.) Even if you don’t intend to use the utility directly, pay attention – The Covert Ops already have a sample pack up full of oscillators, and you can bet the presence of this utility means more will come. (Even Robert Henke was impressed on the forums.)

Live 6 introduced the file format for “Ableton Meta Sounds.” Bjorn Vayner is currently breaking down how the format works, but the short upshot is that you can make oscillator sources that won’t alias for sound design in Simpler and Sampler. The AMS File Utility does more, too – export tunings (even microtuned stuff), and make oscillator variations. It’s sampling for people who like synthesis. In fact, not only is it fun to make additive synthesis-style oscillators dragging individual harmonics, but it’s a total breeze to change the offset and make equal-tempered stuff, negative scales, and other tunings.

AMS File Utility for Microtonal/Traditional Tunings

Thanks for reminding us of this, Tony. I’m a bit behind on all this, but better late than never. Since I am lagging, has anyone made some AMS packs since this came out in September?

Don’t get too excited. Gibson Guitar is not, in fact, introducing a fully robotic guitar. Or a creepy robot doll that plays a guitar. Nor are they shipping you a handsome (male/female/your choice) robot assistant who will follow you around and tune your guitar for you. Too bad. But they are launching a robotic, self-tuning guitar on December 7. And most importantly, it comes in a limited-edition frost blue paint retro-robotic job, which even as a non-guitarist, I have to admit is super hot. So, what’s robotic about it? Its tuning system:

In addition to its automated tuning and alternate/open tuning functions, the Gibson Robot Guitar offers a unique Intonation function, which guides even the most tweak-phobic player through the simple steps of achieving perfect intonation on this revolutionary instrument. No tools or external tuners or other gadgets are needed other than a small screwdriver and the Robot Guitar’s own Master Control Knob (MCK). The guitar itself “talks you through” the entire process, resulting in a correctly intonated guitar in a fraction of the time it takes even a professional guitar tech to do the same job.

Ah, YouTubers. While the rest of us pontificate endlessly, the unfairly-maligned YouTube community painstakingly assembles evidence to prove their point. Lonely girls need outing? YouTube is there. Can’t tell what’s wildly out of tune in a botched Van Halen “Jump” performance? Let’s just listen, shall we? (Too bad, as I had just worked out a really great theory about sun spots, Greensboro’s atmospheric pressure and relative humidity, and a freak wormhole.)

Thanks, Wilfred Fumbly. (video’s gone now … more in a moment)

So, the original theory holds: most likely a sample rate issue. Well, unless Van Halen is really old school, run their backing tracks on reel-to-reels, and had that set to the wrong speed. Sample rates it is.

More importantly, we’ve definitively proven Eddie is a “great guitar player,” which I know is what was really bothering everybody about this clip. He demonstrates this greatness with true vigor, by playing as loudly as possible for five minutes completely out of tune with the backing track and the vocals (which were matching the backing track) as if he’s completely deaf. If you had any doubts about what a true Guitar Hero is, now you know. (And yeah, unfortunately, I do think that really was his only choice. Guess the techs couldn’t get the clock rate set back to normality.)

Speaking of Guitar Hero / Rock Band: Activision / Harmonix, if you’re listening, I think you know what my request for an Easter Egg in your game would be.

Updated: The video is gone. So now we can not only speculate about what happened to Van Halen, but what happened to the video. Perhaps WilfredFumbly noticed that, while the keyboard part in Greensboro was pitched higher than the original album recording, so were other gigs on the tour. That means the guitar is far from absolved. And it lends new credence to my “Wormhole Theory.” Maybe Eddie’s guitar was temporarily replaced with one from the past, in which the song was in a different key, or even an alternate universe where this is in tune.

Okay. I got nothing.

My God … it’s full of keys!

While the black-and-white piano-style keyboard layout remains the standard, designers still look for ways of reinventing pitch in music controllers. Sometimes the aim is to make it easier to play harmonies (top) … and sometimes it’s 211 keys-per-octave microtonal mayhem.
