Foot-based controllers are a wonderful thing for music, because we usually greatly overburden our hands with tasks — play guitars and keyboards, twist knobs, run faders, etc. It’s not hard to imagine the Wii Fit board as an expression controller, in place of a pedal. And it shouldn’t be hard to get data out of it, either, since it looks like it also uses Bluetooth, just as the Wii controller does. (Musicians and DJs, among others, have happily employed the Wii remote in creative applications for Mac, Linux, and Windows.)

While we wait, though, I’d like to ask another question: does anyone know of creative uses of foot controllers for music over the years? Most of what the Wii remote does had been done previously in various forms by music researchers, composers, and inventors, up to a couple of decades before Nintendo shipped their remote. That’s not to say Nintendo was ripping off their efforts; on the contrary, it suggests the design of controllers is more than just fad and will continue to evolve.

So — fabulous foot inventions? We’d love to hear them.

Electronic duo The Crystal Method has produced a continuous album called Drive designed for use in a 45-minute workout, promoting Apple’s new partnership with Nike. The Nike + iPod combination is more than just marketing: a sensor in the shoe transmits data to the iPod Nano and gives you aural feedback on how you’re doing. You can upload the results to Nike’s website and view your progress in a nice, Flash-enabled viewer. The music itself isn’t interactive, so you could use it with any player. What The Crystal Method have done is to pace their music to encourage you through your workout, down to “power phrases” repeated in the vocals. (“It’s time to get moving,” “Here we go,” “Move your lazy ass,” “Thanks for moving your lazy ass; now you are truly an awesome demigod of fitness,” etc., I think is the general gist.) And, of course, there is something about electronic music that motivates motion.

The Crystal Method: Drive

This is all well and good, but it seems the technology may go a lot further in future. The iPod’s internal processor isn’t powerful enough to do much in the way of musical synthesis, but I sure would love to see generative music that adapts intelligently to your movement. The Crystal Method track may well be worth the $10 to get you motivated, but it’ll eventually get old. Imagine a composition that sounds different each time, and helps you out when your pace starts to sag. And, of course, I’d like to see us get beyond tired electronica cliches for moving your body. There have to be some new opportunities for inspiring movement.

But interactive fitness composing? Absolutely.

In the meantime, the technology I really need is something that lets me work out while I’m sitting at my computer working on all this stuff. Maybe I should just try to dance around more as I sit here. (Apologies for forthcoming spelling errors.)
