Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

Korg Gadget for Windows - someone here who bought it?
It's out for a while now, but according to the Korg website there are still quite a few gadgets missing for the Windows version ( "...will be added sequentially in the next update" ):

Someone here who bought the Windows pack and who can confirm this?
I'd really like to buy but I'm afraid Korg somehow delays the updates to infinity and most of the plugins that are still missing are the ones I'm interested in
