Audio gear maker Apogee has announced updates to three Mac-oriented USB interfaces. For the whole trio the company is introducing a new Maestro iOS app, giving the iPad the same hardware control options as the Mac; the app should also work on the iPhone and iPod touch. Apogee's upgraded One interface features two inputs, iOS device charging, optional internal battery use, and new mic preamps and AD/DA converters. An integrated mic and breakout cable can be used to connect a 1/4-inch cable or XLR. The new One is shipping in March at a cost of $349.
