Korg posted a new video to show off Gadget on Mac, along with some details on the three new gadgets!
Two new gadgets propel KORG Gadget to a new level as an audio-compatible all-in-one production environment. Newly added to the collection are the Zurich gadget for general-purpose recording and the Rosario gadget that's optimized for guitar recording. In addition to the audio gadgets, your sound-creating possibilities are further expanded by Recife, a new type of drum gadget with built-in high-quality samples.
Over on the Gadget Collection page they are pretty careful to note when some gadgets are incompatible with some devices. The new Zurich, Rosario, and Recife have no such limitations noted; so I expect to see them coming to iOS!
From iOS to Mac. Music production software to help your musical imagination become reality. More about KORG Gadget for Mac at: http://www.korg.com/korg_gadget/
