We've got MIDI FX plugins in Maschine with the new Modalics plugin - Plugin Buddy.
Really easy to use. Works with Ripchord or Scaler or any Midi FX. Plus it has a couple built-in (including transpose).
When using Ripchord, it doesn't show all the notes played in the piano roll - just the note pressed on the keyboard.
So if NI don't deliver this, we have it already.
