Keyboardists of the world, step up to the front of the stage! The Alesis Vortex is said to the first “keytar” strap-on keyboard with USB capability with support for Mac, Windows, and even iOS (with the optional Camera Connection Kit). There are 37 keys, a touch strip, a volume slider, a pitch wheel, and an tilt-sensing accelerometer that can be assigned to various parameters. There are also eight trigger/drum pads for laying down rhythms. The Vortex can run on batteries or bus power over USB.
