Fans of the Nintendo DS may have been immune to the siren song of Nintendo’s tweaked DSi model. Unfortunately, I have a feeling a bunch of you are about to upgrade your handheld game system. Why? Because the folks at AQ Interactive are doing an upgraded version of the DS-10 software synth for the game platform, now on the DSi. Palm Sounds gets the scoop.

New in this version:

• Twice the analog synths (4 of them, instead of 2)
• Twice the drum machines (8 instead of 4)
• Twice the tracks (12 instead of 6)
• Expanded song mode: programmable track mute, realtime editing (that is, edit parameters inside the song mode

They’re also announcing distribution through retailers. The new features appear to be platform-specific — that is, all this doubling business appears to be thanks to the greater horsepower of the DSi. My guess – though this is unconfirmed – is that if you can get this for the pre-DSi DS, you won’t be able to switch to the “Dual Mode.” The other slight disappointment is that it doesn’t sound as though online features or collaborative features have been enhanced. On the other hand, AQ is promising that they’ll be in brick-and-mortar retailers, not the online-only distribution they had on the original. I’m hopeful that may also mean distribution outside the US — either for an online DSi purchase, perhaps, or for the cartridge. (The DSi still supports physical carts – hence the mention of retailers.)

The best part of all of this, though, is watching Nobuyoshi Sano – the composer/arranger behind Namco games like Ridge Racer and Tekken – do a Steve Jobs keynote impression.

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.

It’s not lost on me, either, that I’ve complained about Apple’s App Store approval for iPhone and iPod touch as being vague and inconsistent with a few apps, while Nintendo and Sony and Microsoft’s Xbox only allow a few apps to ever see distribution. But now that the game makers have online distribution, I wonder if that could change. Movie multiplexes once promised that, amidst a few dozen screens, one would show Bollywood and experimental film. Perhaps these stores could have an “enter at your own risk” category for homebrew. Sony, after all, is desperate to recover sales lost on its PSP. And I have to admit, I think homebrew is, sadly, partly at fault. Homebrew developers and users painstakingly document hacking steps because it’s the only way to get their software on the device – only to have the same system abused by people who don’t want to pay for games.

Korg came out with its DS-10 app for the Nintendo handheld officially, and it was an enormous, runaway success, spawning YouTube virals and entire bands. Now, granted, the app had a major commercial publisher behind it (AQ Interactive), adding credibility – but distribution was limited by the physical cartridge, and the app itself didn’t shy away from Big Boy, niche soft synth controls.

8-bit musicians will likely never touch the DSi, preferring the vintage Game Boy. But a few hard-core gamers are also hard-core handheld musicians. Underground is great, and there’s a certain ethos around hacking. But access isn’t such a bad thing. If just one advocate at Sony or Nintendo would consider it, I think wonderful things could happen.

Now, if you’ll excuse me, I have to see if it’s possible to get a DS homebrew music app running in an emulator on my Android.
