It’s been one of the few constants in music technology. To use Pro Tools software, you need Pro Tools hardware – that means M-Audio interfaces for M-Powered (and now Essentials) and Digidesign interfaces for LE and HD. Without M-Audio or Digidesign hardware actively plugged in, the software refuses to run. And there’s no way for a third party to get their audio hardware working with the software.

Or so everyone thought. Without the cooperation of Avid, Mackie says they have managed to get their Onyx-i mixer line working with Pro Tools, and they’ll even “certify” compatibility. At the end of July, a number of audio sites (including Mix and Sonic State, but not CDM) received a package with one of Mackie’s new mixers, a video, and a copy of Pro Tools M-Powered. The message: a “secret” driver provided compatibility between Mackie’s mixer-audio interface package and Pro Tools. (See Sonic State’s writeup.)

So, what’s going on?

Onyx-i – What’s “i”mproved

Before I get into that, first, a word about Mackie’s new Onyx-i mixers. Viral videos aside, I already know many CDM readers don’t actually like Pro Tools, and the Onyx-i has plenty of other features to recommend it. The original Onyx was already an interesting solution, with the potential to combine a full-blown Mackie mixer with a FireWire audio interface. But the hardware was bulky, and adding FireWire support required buying and installing a separate add-in card.

“Studio” for many of us means packing musical production tools into a corner of our desk, then being able to fit the whole thing into a backpack and take it with us. It’s bringing along your entire production to a cramped rehearsal room and adjusting tracks in a hotel room. It’s putting together an assortment of unusual pieces of DIY hardware, mobile game systems and an iPod touch, and composing and performing a live PA set. So packing in functionality means a lot.

That makes it worth considering a hardware solution like Cakewalk’s V-Studio 100 in obsessive detail. Combining an interface with mixing, control, recording, and software functions makes the VS especially relevant to the computer musician.

I was one of the first people outside Cakewalk to lay eyes on the V-Studio 100. Part of the initial appeal to me was that it seemed to combine a lot of the tools I wanted into a single package.

Sure, its big brother, the V-Studio 700, is an impressive unit with loads of onboard options. But the V-Studio 100 was more my speed: it has that apartment studio, backpack-friendly attitude. And don’t let the “SONAR” in “SONAR V-Studio 100” fool you, either. While it’s great having a free copy of a special edition of SONAR on Windows you can use the VS hardware and even the plug-in bundle that comes with it on any host on either Windows or Mac. And — oh, yeah – you can also make use of all that audio I/O and mixing to do some crazy stuff with your plugged-in portable game  consoles and iPhones and homebrewed electronics.

The real test is whether this one unit can perform the tasks you need. The V-Studio 100 tries to be a number of different things:

• An audio interface (up to 24-bit/96 kHz)
• A mixer
• A control surface
• A wave recorder
• A software bundle

Correction: The street price of the whole package is US$699. (I had incorrectly put the street at $800 instead of $700!)

Anything that does that much will naturally have to make some compromises. Some of those compromises I think are rather well-conceived on the VS, while others I hope will evolve over time.

This will be partially a review, but partially a description of what it’s like using the VS, so if you do have one of these, I can hopefully give you a sense of how to begin using it.

Sometimes, audio products come in sexy, exciting packages. But sometimes, they simply solve a set of problems. And the products that fit into the latter category can be as beloved (dare I say sexy), if not more so.

Since I first saw a prototype in the fall, I’ve been eagerly awaiting trying out Cakewalk’s V-Studio 100. It immediately resonated with features I wanted to see in hardware. Rather than talk the specs, let’s talk about the kind of problems you might like to solve in your mobile rehearsal, production, and performance rig:

• You want to mix live, but don’t want to carry a mixer. You’ve got a laptop set, but you’re mixing it with other sources – and you want to be able to add live instruments / voices / Nintendo DS / circuit-bent creations to your main output without routing through the computer (which also saves your bacon when the machine crashes / you accidentally overload the CPU in Live)
• You want to record your live sessions. ‘Nuff said. Sure, you have a portable recorder, but then you have to patch it in…
• A lot of the time, you reach for the mouse because a control surface wasn’t convenient. And then there’s the fact that, while keyboards now often have mixer controls, the faders aren’t motorized.
• You want to carry less gear, but you really need an audio mixer and some live effects and some recording and a control surface for your software mix.

And, of course, yours truly has been sort of encouraging all of these problems with talk of Game Boys and iPhones and custom-built Theremins and actually playing live instruments and pushing your Live set to the envelope and … oh yeah, then you want to record the whole thing.

I can’t vouch for whether the V-Studio 100 fulfills all my wishes just yet, because I don’t have the thing here. But while there are inevitable compromises in multi-function designs, the V-Studio 100 is set up in a way that appears to come close to what I think a whole lot of us need as laptop musicians. And despite the Cakewalk name, it’s actually aimed at users of a variety of Mac and Windows tools:
