Some of you will recall the original iO Dock, Alesis's first attempt at an iPad docking station and audio/MIDI interface for music makers.
The revised version looks similar, giving you a pair of combo XLR-1/4-inch inputs for hooking up guitars, instruments and mics, plus MIDI I/O on 5-pin jacks. The high-impedance guitar input is said to have been improved, but the bigger news is that, thanks to the interchangeable 30-pin and Lightning connectors, the iO Dock II is compatible with all the standard iPads up to and including the fourth generation model. The downside is that there's still no support for the iPad Air.
