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.)

Handheld eggs, ironing boards, machinedrums, phones … live setups can involve all sorts of oddities, especially among the rabid (in a good way) Ableton Live fanbase, and we’ll be showing them in NYC. Saturday night, we’ll chill out after Dubspot’s day-long workshop with a free, open party in Manhattan’s Meatpacking District at 675 Bar to explore some new musical interfaces, have a few drinks, meet each other, and hear some new sounds. [Facebook RSVP]

For more on the whole week’s events with Dubspot, see our previous post.

Confirmed lineup:

• Isomer Transition (aka RJ Valeo) doing some superb-quality techno with lots of knobs and a machinedrum + Ableton Live
• Ted Hayes’ EggBeater wireless shaker for rhythms, built in free software Pure Data and used (in this case) with Ableton Live
• Sound artist Ranjit Bhatnagar with a musical MIDI ironing board (pictured below) controlling Live, as seen at Handmade Music (at which it was covered by Wired.com)
• Track Team Audio’s Michael Hatsis showing some tweaked-out Live control in action – hopefully including his APC40 hacks and monome patches.
• Me, playing a set with control TBD – possibly Lemur and/or my Android phone

The “beater” application is really quite nice, and follows with a lot of handheld-style, gestural controllers we’re seeing lately. That could mean that soon we could have some sort of software layer that works with any of these controllers — substituting, say, a Wii or mobile phone. Here’s a great video from the ITP show (the bi-annual exposition of the work of interactive technology students at New York University):

Gestural Music Sequencer from Unearthed Music on Vimeo.

Something as simple as remapping a single knob can give you new musical ideas. So expand that to entire gestures and live video input, and you can help push your performance in new directions and out of old habits. That’s why it’s always great to see projects like the Gestural Music Sequencer.

Built entirely in free tools – tools fairly friendly even to non-coders – the GMS lets composer and musician John Keston explore new ideas through gestures captured in a video stream. It’s easier to see than to talk about, so check out the just-completed documentary short by Josh Klos, with the aid of Julie Kistler and Brian Smith. (And yes, documentation makes a huge difference; we’d love to see more of this stuff!)

The ingredients:

• Processing, the free, multiplatform coding environment [site | cdmu tag | cdmo tag]
• controlP5, a lovely, light, quick-and-dirty library for UI controls
• Ableton Live – though you could substitute other software via MIDI, Live makes a nice, familiar interactive music engine

There’s plenty of rightful skepticism about the use of mainstream displays for multitouch in general purpose computing. And why not? As a full-time replacement for other input, multitouch probably doesn’t make sense. But for music, the equation is changing. Multitouch capabilities are showing up on commodity-priced PC computers like the multi-touch enabled HP laptop models – the tx2z seen here starts, incredibly, at US$850. And because computer musicians are looking for more control, having a touch-enabled display (even single-touch) just makes sense.

The screen for a laptop musician is a huge piece of real estate. Finally, instead of sitting dumbly in front of you glowing, it can become an X/Y controller or give you shortcuts for controls or provide additional parameters. Yes, using a touchscreen exclusively can result in the dreaded “gorilla arm.” The ergonomics of using a vertically-oriented screen are extremely poor – if you use it exclusively for an extended period of time. But if you look at the way people are using these touchscreens, for incidental control in combination with other things – and the ability of convertible laptops to transform into a horizontal orientation – I think this is no longer the deal killer it once was.

At top, an HP laptop ($850) plus the free version of Sensomusic’s Usine is all you need to create a multitouch interface for Ableton Live. Correction: right now this is limited to single touch only, but multitouch is supported in the hardware, in drivers, soon in Windows 7, and support is promised for a future version of Usine. The point still stands — as does the ability to optimize controls for your fingers. Being able to use more than one at once will, of course, be that much better.

Fractal (see Myspace) uses the combination to play Ableton Live with some simple controls. If you get hooked on Usine, you can get the full “Pro” version for EUR70 with additional patches and objects.

The one major remaining obstacle to multitouch, at least, is cost. If you don’t especially fancy buying a new HP laptop, add-on kits still run in the range of US$800-900 (meaning, ironically, you might as well just buy the HP instead). Laptop vendors are still slow to adopt the technology, though that could change when Windows 7 ships later this year. (On the other hand, tablet PCs, even when they were shipping in relative quantity, often were constrained in available configurations and either skimped on specs or demanded a significant premium.)

But let’s not complain too much. The simple reality is you can add an HP laptop now to a live rig as a performance instrument for under a grand.

Moldover at the Maker Faire from The Amazing Rolo on Vimeo.

Yann Seznec aka The Amazing Rolo brings CDM his coverage of music tech at the Maker Faire in three episodes today.

Our friend Matt Moldover is a mad scientist of controllers. Stock Novation and M-Audio keyboards enter, and wind up coming out as live musical control monsters. You know that kid who mashes up toys in the first Toy Story movie? It’s like that, only musically productive.

Moldover has been steadily perfecting what was originally the Octamasher, a set of M-Audio keyboards connected to a central Ableton Live brain. The basic concept is a powerful one: instead of one person, one set of secret mappings even the performer (cough) sometimes forgets (yeah, that’s me), and one computer behind which he can hide, get a bunch of people jamming and remixing live – even if they’re new to computer music.

The Syncomasher is the latest iteration, and it’s looking utterly beautiful. It can be an installation toy or a serious performer instrument – or both at once. Check out the new custom body – which still retains that whimsical Moldoverism.

Check out this controller modification how-to, as well, from last year:
