Yesterday Korg announced that Gadget will not be ready for their announced launch on February 28th. The new release date has been moved back to late March. Korg cite a need for additional testing, as the reason for the delay. At least they aren't shipping a broken app!
Korg aren't providing a lot of details on the delay, leaving plenty of room for rumors to spread. One such rumor is that they are delaying the release to coincide with Audiobus 3. I spoke with Audiobus developer Sebastian Dittmann this morning to find out if there was any truth to that. He thought the idea was laughable, since the Audiobus 3 SDK is fully backwards compatible. There is absolutely no need for updates to be delayed, as we have already seen in the recent updates for Elastic Drums and modstep.
