Today KORG updated their apps to support Virtual MIDI and Audiobus. So now we can use our favorite DAWs - Cubasis or BeatMaker (they both support midi out and audio tracks) with KORG apps. And thanks to the Audiobus we can record in audio what we play in iPolysix (you can do the same with iMS-20 or any other synths that support MIDI and Audiobus). I recorded video showing how it's all work together. Try it the same on your iPad!
