MOTU did not respond to CDM’s inquiry regarding Mac OS X 10.6 – but they have just posted the most interesting update I’ve seen yet. They have drivers ready for their hardware today, and (nearly) full compatibility for their entire product line. They also suggest that 64-bit support is in the works for their applications, which would make MOTU the first audio software developer I’ve heard even breathe a word of discussion of 64-bit. I couldn’t even get a solid commitment to 64-bit from Apple’s Pro Apps folks (though Apple tends not to talk about things until they’re done). The appeal would be clear – MOTU could give their sampling apps access to greater memory.

MOTU has a comprehensive update page, and I’ve added the news to the http://createdigitalmusic.com/snowleopard round-up page.

That said, while MOTU has the greatest level of out-of-the-gate support I’ve seen from any vendor for 10.6, even they have run into a showstopper issue. Their Ethno Instrument isn’t yet compatible; an update is expected. Sure, that’s just one instrument. But the lesson here? If you don’t mind the occasional wrinkle, you can live on the bleeding edge. But if you want to keep your software up and running, your best bet is to be patient and wait to upgrade. That’s not to discourage you from testing the latest-and-greatest, it just means you need to have the expectations to match.

The news remains, though: MOTU does have updated drivers for those of you with MOTU hardware or software who want to get a head start on setting up Snow Leopard.

That does not seem to be the case with other hardware vendors (Pro Tools, M-Audio, Tascam, and PreSonus all suggest waiting), and even some of the drivers that will initially become available should be considered “beta.” That is, they may even be designed to work with 10.6, but could use additional testing. I think that could probably generally be said of this update for musicians – just as with any significant operating system update on any platform.

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.

Volta and the Buchla 200e from Matthew Davidson on Vimeo.

Computers speak digital signal. Analog synths and modulars speak control voltage. (It’s sort of a “men are from Mars, women find these metaphors insulting” kind of situation.)

What if you could bridge the two elegantly and graphically, using a drag-and-drop, modular interface with calibration and control features? MOTU has developed a solution called Volta. It’s a plug-in that turns your audio interface into a control voltage device. It works with all MOTU audio interfaces that have quarter-inch outputs, and MOTU intends to make it work with any 3rd-party audio interface with DC-coupled quarter-inch outs.

In other words, one software plug-in does more than what a similar module would do, more easily, more elegantly, all from your Mac. It makes your computer a powerful tool for analog synths in a way that it hasn’t been before – arguably in a way that even digital synths can’t approximate.

I’m pleased to welcome Matthew Davidson of MOTU in a CDM exclusive on Volta’s launch. He describes in detail what Volta is about, and why MOTU developed it.

What is Volta?

Volta is software; a virtual instrument that turns your audio interface into a voltage control interface. Anything with a control voltage (CV) input can be automated from your DAW with Volta. This includes modulars, analog mono synths and even effects processors like the moogerfoogers.

Volta provides access to the automation system of your DAW through ramps. You can draw in whatever whacky timeline based automation you desire and use this high resolution data to control anything with a CV input. No stair-stepping or zipper noise. You can also route any MIDI controller to control voltages. Volta provides audio-rate rendered software LFOs, step and trigger sequencers.

Each instance of volta supports up to 24 slots of outputs, and you can have as many instances of Volta as your hardware allows. For example, a MOTU PCI-424 system with four 24io interfaces provides 96 channels of output.

Of course, you can also use Volta to send note information. MIDI information goes in, and control voltages go out. All control signals are running at audio rate, and MIDI note playback is pre-buffered. This provides sample accurate timing of your external hardware.

MOTU’s new drum machine is a new software sampler/synth workstation for drums, clearly influenced by beat production workstations like the legendary Akai MPC and EMU SP1200. With all today’s hardware/software talk, I initially thought this was hardware, too, but it’s not – meaning it’s got an uphill battle against integrated features in hosts like Live and new tools that integrate more closely with hardware, not to mention existing entries like FXpansion’s GURU. But don’t write it off just yet: an internal synth, a unique sampling plug-in, import workflows, and retro groove emulations could keep this in the game.

Oh, yeah – and, typical of MOTU, there’s always one feature that can make you forget every other complaint. For me, that’s the “Line templates” in the step sequencer that let you add your own Euclidian polyrhythms. Nice.

MOTU’s ad copy waxes poetic about the deeper meaning of all of this, as though pondering aloud:

“Sound libraries these days are awash with loops. And what is a loop, exactly? Someone else’s beat. Isn’t it time to take back creative ownership over your grooves?”

Yes, indeed, what is a loop? If you’re curious, you could check out the, um, loop content that ships with BPM in its 15 GB sound library.

The slightly self-contradictory philosophizing ad copy aside, though, I’m all about the creative possibilities of drum workstations, and there’s no question BPM has some potential. Look for a smackdown with NI’s own entry, which we get to talk about later today. Here’s a basic look at the BPM, which I’ll update once I can talk about Maschine oh, any software drum machine that might theoretically come out in the next two hours:

Let’s start with the important bit: the Traveler really is a mobile interface. It weighs under four pounds and fits into a backpack; it’s actually a little lighter and more compact than a typical 15” laptop. Now, if your input and output needs are limited (a mic in, headphone out, and stereo out do suit a lot of folks just fine), your options are obviously many. But the Traveler manages to be this small and pack an absurd amount of I/O and functionality into that small space.

Audio interfaces tend not to get a whole lot of updates, but MOTU has been steadily upgrading the Traveler. New in mk3:
