Making music with your iPad.     I’m Fred Fishkin with technology BootCamp,  a report on gadgets and gear.   If you play guitar or piano, there are lots of ways to connect to the digital world.   Solutions from a company called IK Multimedia have been winning over fans with their quality and simplicity.   There’s iRig KEYS, a small piano keyboard controller that works with iPads, some  iPhones and iPod Touches and even Macs and PCs.     It works with Apple’s Garage Band or with iRig apps like iGrand Piano.  While it sells for under a hundred dollars, it has features that will be appreciated by serious musicians as well as beginners.   Want to get kids to practice the piano?   Put them with iRig Keys and an iPad.  On the vocal side,  the iRig Pre  lets you easily use pro quality microphones with iOS or Android phones and tablets.   There’s more info at IKMultimedia.com.   You can find us at BootCamp.com.
