Korg New microKEY AND microKEY AIR (video)
"Korg brings you even more compact controller options with the new microKEY and microKEY AIR Series:
microKEY can be completely powered by an iPad or iPhone and now offers a pedal input for sustain (micoKEY25 offers a sustain button). There’s also a new 49-key version for the two-handed player that still wants compact.
microKEY AIR – To accommodate simpler and quicker setups, or to simply unwire and unclutter your rig, the microKEY Air series features Apple’s Wireless Bluetooth LE (Low Energy) standard, which provides long battery life and extremely low latency! They also have standard USB connections.
Both come with a comprehensive software bundle to advance your plug in library, or serve as your starting point to making music using your computer or iOS device!"
