iRig Keys is the first ultra-slim and highly portable universal MIDI controller keyboard for iPhone, iPod touch, iPad and Mac/PC. iRig KEYS connects directly to the iOS device's 30-pin dock connector, Lightning connector (Lightning cable must be purchased separately), or the USB port on your Mac/PC. It features 37 velocity-sensitive mini-keys — a full 3-octave range plus one note. iRig Keys features an easy-to-use control panel that gives you 5 backlit soft-touch buttons and one volume/data knob. You will find Program and Octave up/down buttons plus a Set button that will allow you to store up to 4 different set ups for the complete iRig KEYS configuration. An Edit mode is also available to transpose the keyboard, send specific program change messages, customize touch sensitivity, change MIDI channel, reassign Vol/Data knob MIDI control change and access to other useful MIDI functions in a flash.
