For all the focus on clever little music apps on your phone, it’s the slate/tablet form factor that seems to hold the greatest promise for live performance. Thanks to a larger screen area, these devices look far more usable for control – equipped with multi-touch, they could be reasonable substitutes for hardware control surfaces, a la the Lemur.And with greater horsepower under the hood, you might not need to use them as a controller – you could run an entire live gig off them.

With this week’s Consumer Electronics Show (CES), many onlookers expected news on these devices, particularly as industry buzz anticipated a big announcement during Microsoft chairman Steve Ballmer’s keynote last night. And we got that news – sort of. Unfortunately, manufacturers teased “concepts” and prototypes, without much in the way of details – a repeat performance of 2009’s fuzzy glimpse at this device category.

That said, having been wrong about when it’ll happen, I’m still convinced we’re about to see a flood of new PC devices with interesting potential for music performance. Here’s what we’ve got so far:

Max for Live is a fantastic product that treads on genuinely new ground. Its level of integration with the user interface and operation of the host reaches a new high, it comes with a rich selection of instruments, effects, and tools to use as examples, and, in combination with Max 5’s re-vamped interface, makes a comfortable development environment. It does all of this inside a host that, true to its “Live” name, provides a unique workflow.

But Max for Live also comes with some significant strings attached, and it confirms some of the disadvantages to Max as a proprietary, vendor-specific development solution for music and performance. That means that it’ll be a superb choice for certain applications, but will fail to be a viable option for others.

Technology is about trade-offs; understanding those tradeoffs is essential to making informed decisions. There’s never a “right” choice; only a right choice for you. I think the music tech community will embrace Max for Live, but it’s also important to have alternatives. The DIY creative music community likely won’t – and certainly shouldn’t – simply make Max for Live and Ableton Live its tool for everything.

In summary:

1. Max for Live doesn’t have a free run-time, which means it’s not your best option if you want to reach a wide audience with your creations.

2. Max is no longer an option for people wanting to develop plug-ins for multiple hosts, a change that didn’t go over well with all developers partly because it was only revealed after Max 5 and Max for Live.

3. Jitter output while editing is crippled in Max for Live if you don’t also own Jitter.

4. Max isn’t an open source tool, which has practical implications, including -

5. You’ll want to choose something else if you’re interested in mobile music making.

You’ll want to weigh these options when considering Max for Live, even before considering the technical specifics of the tool. You may determine it’s still the perfect tool for the job, or you may not; it should simply be part of your equation.

These aren’t entirely black and white issues, so I’ll be specific:

Mint.com, the online financial management tool, has put its numbers together with market researchers NPD Group to analyze music spending. The results: when it comes to consuming recorded music, digital music continues to rise. At the same time, so does Apple’s grip on the music consumption market, a combination that includes proprietary control of a music store, a music player, and the leading mobile device.

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.

A young, aspiring musician walks into a consumer electronics store. (Let’s call it Big Buy, and imagine people wearing… red polo shirts.) They wander into the game aisle and muse at the latest music games in the video game section – $60-100 in price. But there’s an endcap with something else: a box of Pro Tools that’ll run on their computer, plus a ready-to-use audio interface, for $99-129. Instead of Guitar Hero, they leave with Pro Tools – a name they already knew.

See full details of the new lineup, with photos.

This idea is nothing new – for many years, it’s been possible to do great stuff with $100 on a computer. But the most powerful brand in music production (Pro Tools) has remained notably absent. Instead, that hypothetical consumer would find a smattering of consumer-only choices with names they likely wouldn’t recognize. Meanwhile, the name “Pro Tools,” and the software interface that made it popular, have been limited to more complex offerings sold through specialists.

Today changes all of that. Gone is the idea that “Pro Tools” is only for the high end. Gone is the iLok hardware dongle. (You still need either the Micro or Fast Track interface plugged in, but the target market for this product may not care.)

There are three offerings:

A vocal studio, bundled with a USB mic (similar to M-Audio’s Luna).

A “recording” studio, bundled with a simple USB bus-powered audio interface (the previously-available Fast Track.

The “KeyStudio”, bundled with a 49-key USB keyboard. The software comes with 60+ virtual instruments, says Avid, so you’ve got quite a lot to play.

The software included in each has some limitations – it has 32 tracks (16 audio, 8 instrument, and 8 MIDI), and more basic routing options (3 inserts per track, 2 audio inputs, and 2 outputs). The absence of multitrack recording is probably the biggest restriction. But you nonetheless get a range of virtual instrument sounds and effects, plus a full complement of editing and mixing features.

On the same day that people are rediscovering The Beatles through a video game, and video games are causing people to rediscover music making, you can buy a studio for about the same price.

Now, if you’re reading this site, that’s probably not news. But it could be news to quite a lot of people who haven’t discovered computer music making. And it represents a tectonic shift in how the titan of music making software treats its flagship.
