With full size keys, this universal mobile keyboard by IK Multimeda for iPhone, iPod touch, iPad and Mac/PC feels great. iRig KEYS PRO gives you the best of both worlds. It's a super-compact, bus-powered, “plug and play” MIDI controller that you can use anytime and anywhere. Yet despite it's small footprint, it offers full-size, velocity-sensitive keys, allowing for a realistic playing feel. With its 37-key (3-octave) keyboard, you can play legitimate two-handed parts. What's more, it has loads of pro performance features, and comes with cables and software for iOS devices - Lightning and 30-pin - and for Macs or PCs.
