There’s nothing like the Wallander Wivi Orchestra instruments – they’re incredibly expressive yet they don’t take any hard drive space or hog system resources. Now our friends at Wallander have announced Wivi Band, which runs on the Apple iPhone. It’s available through the iPhone Apps Store for $10, but if you’re a Wivi Orchestra user and you need to be portable – and you’ve got an iPhone – then these 15 expressive instruments will let you be mobile until you can get back to your computer and the real-deal instruments. There’s a little keyboard, and the iPhone mic serves as a wind controller. Pretty slick.
