Here's what Korg tell us about the new plugKEY iOS music interface.

Melville, NY - - June 9, 2016 - - Always on the cutting-edge of innovation and aiming to satisfy the needs of music makers, Korg introduces plugKEY, which lets users connect any 5-pin MIDI-equipped instrument - - including their keyboard, home digital piano, workstation and more - - to their iOS device’s Lightning ™ connector to control MIDI-enabled apps. High quality stereo ¼” outputs- and audio out via the same Lightning ™ connection also allows users to connect their iOS device with their mixer, audio interface, or monitors with high-quality D/A conversion. Rounding out the feature set is a convenient volume knob and 1/8” headphone jack. Every plugKEY also includes LE versions of Korg’s acclaimed Module and Gadget apps.

“Korg’s new plugKEY is a tool that every music maker should have access to. There is nothing on the market with a 5-pin MIDI In, stereo ¼ audio out, and optional charging for iOS. It’s really an ingeniously simple and useful MIDI and Audio tool for anyone using an iOS device for music,” shared James Sajeva, Korg USA’s Director of Technology Brands. “It’s also perfect for Digital Home Piano owners, from student to pro level, and opens up a world of control for iOS beyond small USB-only controllers.”

Hi Rounik, I was about to purchase the plugKEY - compact and functional, very cool, but when I looked on the Korg website at the specifications I was very surprised to see that the iPad Pro is not listed under compatible devices http://www.korg.com/us/products/computergear/plugkey/specifications.php. I find this quite baffling, and wondered if it is a mistake, or if it actually does work even though it's not officially supported. Any insight you might know on this would be great to hear.

it doesn’t work with ipad pro 2017 ios 11.2 properly. it starts to crackle when using apps in the background mode, builtin mic or when you use more then one app the same time. neither korg nor apple seem to solve the issue. so for now its just useless.
Hi ReTracer, that's odd. I imagine that's an oversight. Can't imagine why the PlugKEY wouldn't work on iPad Pro but is fine on iPad Mini and other models. Must be a mistake. :)
Would the PlugKey be compatible with an early ipad with iOS 9.3.5., assuming a 31pin adapter for Apple Lightning exists?
