Apple’s “Snow Leopard” 10.6 ships Friday, which means it’s time to start compiling information about the new OS flavor. Just don’t upgrade too fast, as always.

Want to push an operating system to the breaking point? Ask a musician. Between the demands of real-time performance and the complex ecosystem of mix-and-match hardware, software, and plug-ins, odds are your local audio geek will break an OS faster than anyone else. Not every operating system upgrade is going to have a big impact on music software, but keep in mind that even subtle changes can cause issues that may interfere with your work.

Of course, all of this means music users should treat any OS update with caution. :

• If you’ve got a critical, primary production machine, your best bet is often simply to wait. Confirm that software works before you upgrade rather than after.
• If you’ve got some time to invest in an upgrade or have more than one machine, be sure to do a full backup and system image so you can revert to the previous, known working OS.
• Best solution: Boot off an external hard drive. Don’t commit to installing internally until you’re sure everything is working. Once you are, go enjoy. (as noted in comments, and yes, I should have said this initially… still, the latest 10.5 build is still the preferred OS for now.)

So, sit back. Enjoy life. Go for a walk on a beach. Recline in your favorite chair with your MacBook running Mac OS X 10.5 Leopard. Isn’t it great? Need to waste time? Plants vs. Zombies is out for Mac.

What? Still want to upgrade?

Fair enough. We’ll be tracking changes to Snow Leopard and which of them may impact audio.

The short version: Snow Leopard introduces only small changes, but if a developer hasn’t been on top of those changes, you could see issues. And as for the 64-bit mode that’s attracting most of the attention, the short answer is, you can’t use it for music yet.

Native Instruments and Plogue have each responded to CDM with information on their software.

Should sounds be part of a closed format that may not last? What happens if the format and platform that once were trusted by musicians and sound designers ceased to be? That’s the hard lesson learned by users of a popular sampling “standard” – but for once, the news is good.

GigaSampler has been a huge part of the sampling landscape since its introduction a decade ago, and users have massive investments in Giga sound libraries. As I noted over the summer, however, Tascam ceased development on the aging Giga platform, leaving users without an important tool – and some powerful technologies without a home.

Today, news has leaked out that Garritan, developer of some popular sample libraries and (with Plogue) the sophisticated, cross-platform ARIA Engine, has purchased all of the technology assets related to Giga from Tascam (TEAC). That includes GigaStudio, Gigasampler, GVI, Gigapulse, and everything that goes with it.

This is huge news for compatibility, interoperability, and the future evolution of sampling. I spoke with Garritan chief Gary Garritan himself to chat about some of the possibilities.

The most obvious potential benefit is native file compatibility with Giga sample libraries, so that that sound content isn’t stranded in an abandoned, closed format. Gary says native file reading and writing is high on the priority list – which should also be a big coup, I think, for his ARIA platform.

There are some technologies worth saving in Giga, too, though, not just the sample format. Some of the jewels in Giga include the DEF high-quality filtering algorithms, spectral morphing, and convolution capabilities.

“There’s a treasure trove of great technology and we want to make it available to as many musicians as possible,” says Garritan. “We just have our work cut out for us.”

The process of assimilating Giga’s technology is likely to take time, Garritan says:

Okay, so you’ve seen the painful demo video for Microsoft Research’s Songsmith software – it was intended to me tongue-in-cheek, I think, but the self-parody didn’t quite work. But the idea of auto-accompaniment software that interprets your recorded singing remains impressive. And I’ve gotten some tips that it is possible to make Songsmith sound good. Naturally, the biggest variable will be the quality of your own singing. But to make the software side of the equation more interesting, it is possible to extend the tool.

Garritan, maker of the samples in the tool, has two add-ons. There’s an orchestral pack with the usuals, and Garritan’s sampled orchestras do sound very, very good. Better yet, there are some analog synths to add, including some bass, J-60, Jupiter, and other action. These don’t come with styles, but they do give you some new sounds. Whether you use them for more evil and cheese is up to you. US$9.99 each.

Band-in-a-Box maker PG Music also has Style PAKs that are compatible with Songsmith, too. The key with these is adjusting variables in the accompaniment, and tweaking chord progressions.

I can’t say I’m entirely sold yet because I’ve never been a fan of auto-accompaniment – though, okay, I did pass some enjoyable hours messing around with electronic organ and Casio keyboard presets as a youngster, so I take that back.

Here’s my challenge to you, if you are a Windows user and give Songsmith a try. Go. Make something really great. Maybe it takes this in a new direction — sample Hatebeak’s heavy metal parrot screeches. Maybe you just happen to be a brilliant singer. Report back. The world’s ears thank you in advance.

Breaking News: If you were David Lee Roth, and you decided to use Songsmith, you would sound something like this. (Thanks, Neal Johnson! Actually, what’s a word that means not so much “thanks” but “please, never, ever send anything like this again, for the love of all that is good?”)

In a surprise announcement (well, surprising me, at least), the experimental MySong shown by Microsoft Research earlier this year will be available for sale. US$29.95 will buy you a downloadable auto-accompaniment tool. Windows-only, but it sounds as though a Mac release is in store (seriously). It’s a bit like Band-in-a-Box for singers: sing in a line, and the software will generate accompaniment to your singing with styles of your own choosing. There are thirty styles included, and apparently Microsoft focused on the content end in bringing this product to market: there’s a 1 GB space requirement and partnerships announced with PG Music and sample house Garritan.

I’m guessing PG Music, the makers of aforementioned Band in a Box, have helped smooth out the slightly unmusical arrangements generated by the first version. Now, okay, admittedly I was skeptical of the output I heard of the first version. Maybe I’m scarred because I had a high school jazz teacher who player trumpet, not piano, and therefore insisted on running Band-in-a-Box over top of me while I tried to comp on keys. But there are reasons this is cool:

• Garritan’s sample content sounds great.
• PG Music has made its auto-accompaniment a lot more musical over the years.
• The thing could be a decent sketchpad for people who find this helps them imagine musical ideas – realizing there’s no substitute for the real thing.
• Most importantly, bringing research to market is a great thing.

And let me emphasize that last point. I love that Microsoft has made this available. Too often, R&D achievements get one demo, a patent filing, and then languish in some dark closet, never to be seen again. Sure, some of them probably were never meant for the light of day, but very often people love the demo and want to give the thing a chance – and why not let you decide?

So a big congrats to the Microsoft R&D team. And here’s to more research seeing that light of day, whether through open source availability or commercial release (or, where appropriate, both).

So Songsmith will accompany your vocals, Apple will get Sting to teach you to play and explain how he wrote Roxanne – okay, as if this week, you really have no excuse not to graduate from Rock Band, ye casual musicians!

Updated: Oh, wait. (*&(*&$#&*. The promo video is … ?

(*&(*&$#&*. Can Microsoft just let Sparrow do all the promotion from now on, please?

Black Friday? Cyber Monday? Who need them? The entire month of December seems to be on sale when it comes to music tech.

Christmas (and Hanukkah, for that matter) are nearly here. Whether it’s economic pressure or just some aggressive holiday pricing, there are some big deals out there that could make excellent gifts – or might just give you a nice list for shopping for yourself before or after the holidays. (Yes, it’s true: most of what readers suggested in our “gift guide” for the CDM Winter 08 special wasn’t really all that practical. But it does make a nice list of things you love.)

Here’s some of what’s on our radar screen:
