The StudioDock is the first device that enables anyone with an iPad to create, produce, and perform music with virtually any pro audio gear or instruments. The StudioDock is a universal docking station specifically designed for the iPad, and it gives musicians, recording engineers, and music producers the connectivity they need to create and perform with iPad. Connect all your pro audio gear to virtually any app in the App Store with the StudioDock.The device features two combination XLR and 1/4-inch inputs (each with its own gain control and switchable phantom power for condenser microphones), MIDI in, MIDI out, USB MIDI, 1/4-inch footswitch input, two 1/4-inch outs plus 1/4-inch headphone out, and video output. With this little dock, your iPad basically becomes a touch-screen recording studio, or touch-screen performance controller, or touch-screen instrument controller, or really whatever sort of touch-screen musical device you would like (assuming there is an app for that).
I can just see myself, up in the club, sippin' on some syzurp, jamming out some ReBirth through the PA, with my keyboard and guitar runnning through my iPad. Sounds like a good time to me. So far, there is no word on Alesis' site on pricing or release date, but I expect this right around the time the iPad 2 is released, so your guess is as good as mine!
