Hello? You know what's just straight-up nuts?
Just (seemingly) a few years ago it cost a hundred thousand dollars to get a Fairlight CMI.
And now it's a freakin' app on iTunes. Yeah, it'll work on iPads and iPods. An App.
Even better is that for an additional seventy bucks you can get this keyboard from Akai -- the SynthStation25 -- and dock your iPod Touch in it. So a Fairlight. For less than a hundred bucks.
