“iPolysix is an analog polyphonic synthesizer that’s been carefully designed to take full advantage of the 7.9-inch display of the new iPad mini as well as the iPad. Bringing together a sequencer, drum machine, and even a mixer, it transforms your iPad or iPad mini into the ultimate analog synth studio. Pack an amazing set of early-’80s analog equipment into your iPad, and time-travel back to the dawn of polyphonic synthesizers!” – Korg
