Good Midi drum app

Can anyone recommend a good Drum app for iOS to integrate with Cubasis.

I like the interface on the apps that represent a real drum kit (a la GarageBand), and the ones I have tried do seem to have decent sounding kits.

I have so far been unable to find one that works exactly as I want.

What I want to do is using the DrumKit interface of an app, record MIDI into cubasis, and then have that Midi played back through the original App via either IAA or Audiobus.

Does one exist ?
