missing functions

Hi,

I am a Cubase 6 user on PC and I recently bought Cubasis for iPad.
This program is fantastic and open a whole world with audiobus.
But there are some elements I would like to get to be able to work seriously as with Cubase 6:

  1. a markers track
  2. more flexibility with time signature (essential!) like 9/4 or 7/8
  3. a tempo/time signature track as in Cubase to be able to change tempo and time signatures within a song

Thanks!
