MOTU is now shipping Volta, the software plug-in seen exclusively here on CDM at the beginning of the year. The Mac-only plug-in finally brings together two distant technologies: virtual software instruments and control voltage are together at last. (You can just forget all about that MIDI and digital business in the middle.) With it, everything from Moog guitar pedals to the Rolls of modern synths, the mind-bogglingly pricey Buchla 200e, can be easily controlled with a computer rig.

You know that cheezy Disney movie, with the astronaut in King Arthur’s Court? It’s sort of like that, as the 21st Century meets the 1960s.

Volta isn’t just about having more flexible control, either: calibration, routing, and automation all become possible.

For more details, it’s best to look back at our January interview with Matthew Davidson of MOTU, as he revealed this creation to the world:

Analog, Meet Digital: MOTU Volta Connects the Mac to CV Synths, Effects Graphically

Pricing is now final, as well, at US$249.

The key requirement: “An audio interface with DC-coupled outputs, such as any MOTU FireWire, USB2, or PCI audio interface with quarter-inch TRS outputs.” I believe that also includes the RME interfaces. Correction: at this point, I’m unsure which non-MOTU interfaces may work. But if you don’t own one of those interfaces, now’s an excellent excuse to buy a fantastic piece of gear. 

Sadly, Volta require an iLok for authorization. Okay, whoever is out there who would buy something like a 200e or a rack of Doepfers, then pirate this software, you and I need to have a little talk. (I’ve seen stranger things, however.)

I can look on at all of this with a sense of awe and mystery, because I’m staying in the digital realm these days. But you can check out extensive discussion on our previous story of how useful this is, and other ways of creating the effect (albeit less-elegant ones). Apparently Trash Audio already grabbed the domain createanalogmusic.com out of spite, though that means I’m safe from getting sucked into your addiction, analog lovers.

Vocoding Voices in Live 8 from Bjorn Vayner on Vimeo.

Continuing our growing collection of Live 8 video tutorials, our friend Bjorn of Covert Operators sends over a terrific tutorial on making use of the vocoder. Now, unlike the “misuse” tutorials we’ve been running, this is actually how this effect is designed to be used. On the other hand, if you’re still interested in misuse – and you’re not terribly interested in conventional effects – this can be a great way to wrap your head around the tool’s proper function, before you start warping it in another direction.

I think it’ll be fantastic having a vocoder ready to use, and if you haven’t played with a software vocoder, Live 8 should be a nice place to start. If any of you take this in another direction, do let us know.

Covert Operators has a whole bunch of downloads, tips, and tricks some available cheap, some free.

Well, fine, Jamie Lidell. Now you go and ruin it for the rest of us. See, none of us playing with a Nintendo DSi will possibly look as good as you do.

I jest, of course. Jamie Lidell, the wildly-talented vocalist, picks up the new, online-savvy take of the Nintendo DS and breathes cool into it. This is what Sony ads tried to do, but Jamie does masterfully. And, okay, don’t expect the built-in sound app on the DSi to do as much as it appears to be doing here – there’s quite a lot of non-real-time, non-DSi remixing going on, even though what he does do with the simple app is genius.

Thanks to Liz Revision for finding this one.

This does bring us to a burning question: Nintendo and Sony, I’m looking at you. When will we be able to run eccentric and niche music creation apps as official software on your machine? Imagine NitroTracker on the DSi download store or PSPSEQ and PSPRhythm on the Sony Store.

AR scratching from vanderlin on Vimeo.

“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.

Is your MacBook Pro a rightie?

Something’s going on with the one or two left-hand USB ports on all MacBook Pros. I’ve heard some issues with hard disks, and now some problems with audio. (Controllers are evidently just fine.) The solution: use the right-hand USB port for audio instead.

Updated: Reader Adam suggests that this is probably due to a difference in power delivered to the respective ports. USB audio requires more power, and so odds are you’re under-delivering on the left-hand ports. I’m inclined to think that this is exactly what’s going on – unless someone knows something else. (Easy way to test: try plugging in the power adapter. Note that this can be an issue with FireWire, too.)

In fact, even if for some reason M-Audio has found another reason behind this, Andy Ihnatko noted the issue with different USB ports and power variation way back in 2008. It affects non-Pro MacBooks, and I expect likely many PCs, too.

The MacBook. All USB Ports Are Not Equal [Wired Gadget Lab]

M-Audio (now Avid) has gone as far as to tell its customers officially to avoid the use of that port for audio entirely. Native Instruments forum users have evidently had similar discussions. Via matt_bot on Twitter:

The use of USB Audio Devices on the Left-Hand USB Port Is Not Recommended.  This applies to ALL MacBook Pro Models (Core Duo and Core 2 Duo).

•    The 15" MacBook Pro models have 1 USB port on the left side, and one USB port on the right side.
•    The 17" MacBook Pro models have 2 USB ports on the left side, and one USB port on the right side.
