iPhone DJ apps destined for the iPad (photos)

For serious digital music nerds, TouchOSC ($4.99) offers a suite of detailed virtual faders and knobs that can be used to control software on a nearby laptop. The controls borrow heavily from the look pioneered by the JazzMutant Lemur controller, shrunk down to a fraction of the size (and price). If the app gets revamped for the iPad's larger screen, it has the potential to become a popular, flexible way to add touch-screen control to a variety of music software.
