Apple begins approving CoreMIDI on 4.2 with the USB Camera Connection kit

I think we’re in for a micro-revolution in music and entertainment apps for the iPad.  MacRumors detailled DJay app last week which took advantage of a number of new features of 4.2:

• - Full access to iPod library
• - Multi-tasking: you can run djay in Automix mode and listen to a continuous, seamless mix running in the background while you surf the web, play games, etc.
• - AirPlay: you can wirelessly stream your mix to your Apple TV or AirPort Express station in real-time.
• - Fully leverages accelerated CPU extensions (SSE-like) for high-quality audio processing and analysis
• - Very low latency (< 3 msec)
• - Background audio playback (multi-tasking support)
• - Pre-Cueing (via mono/stereo adapter)

The first crop of apps that use CoreMIDI on 4.2 with the USB Camera Connection kit are hitting the App Store. Here’s Luminair:

Perhaps not as cool as DJay:
