DJs, laptop musicians and anyone looking for a viable mobile solution can use it to trigger analog synthesizers, create beats on a smartphone or tablet, control a DAW and more. The iRig Keys 2 controller series, which also includes iRig Keys 2 with 37 mini velocity-sensitive keys and iRig Keys 2 Pro with 37 full-size velocity-sensitive keys, offer many ways to connect and control. The ultra-slim MFi (Made For iPhone) controllers not only offer compatibility with laptops and desktops, but can also connect directly to iPhones, iPads, and most Android models, and also have a dedicated audio output for connecting speakers or headphones - especially useful for newer iPhone/iPad models without headphone outputs. Each controller is also equipped to be used as a standalone MIDI controller or MIDI interface through the knobs provided, as well as MIDI IN/OUT. To get you started right away, each controller comes with a selection of music-making apps and all the necessary cables.
