The PowerMate from Griffin is an affordable, very compact USB knob with glowing blue LED feedback and push-and-turn functionality (so it’s a button, too). But using just one knob may not be all that useful for control. We’ve already seen Robert Hodgin VJing with four PowerMates, but our friends Bill Van Loo and Joshua Schnable have come up with a novel solution. Using Schnable’s custom software built in Pure Data (Pd), they’ve not only mapped the PowerMate to MIDI, but using switches and the push function allow you to control four or eight channels at once using just the one knob.

At the end of last week, they offered a first look at the solution, with a basic demo in Ableton Live (though any MIDI-capable software will work), and downloadable Pd patch and manual to get you started. The patch is open source-licensed.

announcing CTRL4 + CTRL8: MIDI Control for Griffin PowerMate + PureData

Of course, if you’d rather use OSC or create an instrument right in Pd, you can do that, too, with this as a template. But if you want to get up and running with your PowerMate – even if you’ve never used Pd – this should be quite accessible.

Check it out in action in the video below. More documentation is coming.

The manual itself is written from the Mac perspective, but with any MIDI loopback tool on Windows, it should work, too – and I believe some people are even using the PowerMate on Linux. If anyone wants to share how you’re using this on another platform or with another setup, that’d be great, in a noisepages post/blog or anywhere you like – just let us know. (Documentation, suffice to say, is a huge part of going open source.)

This might be worth trying with similar hardware like the (discontinued but still available) Logitech NuLOOQ Navigator, as well. (The NuLOOQ is more expensive list, but looks like prices are as low as $30, and it adds additional controls like a ring on the top.)

Some time ago, we ran a story on a boutique German synth called the Rozzbox. Laden with knobby goodness, the Rozzbox was available only in limited quantities, and only to those fortunate enough to be in Germany (or somehow miraculously got in touch with the creator and pried one from his hands).

Tweakers rejoice! The Rozzbox has finally made it to the US, with distribution being handled by Big City Music. Still only available in limited quantities, we suspect that the Rozzbox will go fast – even at nearly $1950USD. Its unique architecture sets its tone somewhere between a broken-DX7-run-through-a-Sherman-Filterbank and an old-school gaming system turned synth. Full specs available on the Big City Music site, and demos available on the Rozzbox site (in German).

Ed.: Looks like this one has tweaked the interest of Chris @ Audio Damage, too.

And here’s a video in action from the folks at Big City Music that gives you a sense of its range of timbre. (Sure you can make it more musical when you take it home and off the chaos of the show floor!)

I asked creator Gilles Moncaubeig for some advice about where to buy this. In Europe, you can buy from R-Digital, playback.fr, and Mix Experience. It’s even on an eBay.fr store for 389,00 EUR. In the US, opt for Mix Experience as they will ship from Europe to our shores.

Sure, these new-fangled touchscreens are fascinating, but I can still do a lot with physical faders for a fraction of the price (and with my eyes closed, something that can’t be said for the touchscreen). Got a control surface you love? Hit comments and let us know.

L.L. Electronics RozzBox [non-German readers, just click specs]

No plastic here: aluminum with maple sides. Inside, you’ll find a 4-operator FM synth with adjustable glide (looks like you could route it for virtual analog, too) and the usual filters, envelopes, LFO modulation, etc. The synth looks really flexible, and there are some especially nifty features: external audio input, integrated ring modulation (exterminate! — uh, cough, sorry), built-in sequencers that also function as modulation, and even a tube distortion / filter option. MIDI input / output, even envelope follower in, and, for you true analog junkies, an optional control voltage (CV) input.

Gorgeous, compact, flexibly-designed, and it’s not another cheap Moog clone. Now the only question is, where / when / how much? I’ll get back to you if I hear more.

For some of the most bizarre and unusual music-sound installation art, look no further than Burning Man. Burning, indeed: this desert-based event has in the past featured Eric Singer’s Max/MSP-controlled pyrophone, a propane-powered flaming sound organ. (And, incidentally, that installation is making a repeat appearance this year.)

And what better activity when in the middle of the desert than tweaking knobs and producing strange electronic grooves? That’s the idea behind improbable orchestra, an interactive table full o’ knobs for collaborative soundmaking. Build one yourself: check out the copious design notes. Basic specs: the free Pure Data graphical multimedia development environment is running sounds, gutted Pentium PC with custom power supply, custom circuit board connecting the knobs and fiddly bits thorough a Parallax basic stamp board. (Lots more specs on their site, missing only details of the Pd patch.)

“But,” says you, “I hate knobs. Give me lasers, man.” Sure! You obviously want the interactive Aeolian laser harp, which suspends a series of laser beams through which you can walk to trigger sound. It’s the creation of former NYU ITP faculty member Jen Lewin, now based in Colorado and doing interactive sculpture full-time. She has other fantastic projects like interactive butterflies.

Are you going to Burning Man — or have a project of your own you want to tell us about? Drop me a line!

Thought the hardware recording workstation went out with the 90s, along with the Spice Girls? Think again. Hot on the heels of new hardware workstations from Yamaha, Korg’s got a new workstation of its own:

Korg D3200 Digital Recording Studio

And I have to admit, this thing is actually pretty hot. (The D3200, not Ginger Spice.) 12 tracks of recording, 32 of playback. 40-input mixer. Up to 24-bit recording at 44.1/48 kHz. Like the Yamaha workstation, it’s built as a computer companion, with USB 2.0, drag-and-drop file sharing, and (if you do want it to be self contained) CD mastering and burning.

The Korg also has some twists of its own, focused on realtime control. There’s a 4×4 Knob Matrix for tweaking parameters, which can combined with the Session Drums feature for drum programming, with Tap Tempo and all. (Okay, drum programming with knobs is a little different, but I’ll go with it.) There’s also a 320×240 LCD display. I’m especially impressed with a friendly interface, both on-screen and in knob/fader/button placement. Many previous workstations looked cluttered; this one is perfectly clean.

US$1799 list, shipping in August. At that price, could be a good investment in place of a high-end audio interface and mixer, even for a computer user.

Oh, and in other news: the Spice Girls are getting back together.
