iTunes Connect, the way that developers manage their apps on the App Store, is temporarily shutdown from Friday, December 21, 2012 to Friday, December 28, 2012. Which means the only changes we're seeing on iTunes are those that were previously scheduled. Today the only change in the entire Music category of the app store was a sale on some worthless app I don't even feel like mentioning.
So we've got this instead.
Sound Wand MIDI looks like a fine idea, using the iPhone accelerometer and gyros to generate MIDI data. Unfortunately this demo video is a cacophony that I would not ordinarily inflict upon you. Sound Wand MIDI will be available in January 2013.
