Ah ha!
So it’s a work around to get midi into Cubasis to sit and work on with the iPad.
IT would be really nice if you expanaded this feature to make it more streamlined and well…official, support project exporting in Cubase.
Obvioulsy any audio tracks with VSTs would either have to be omitted or mixed down to individual audio files but being able to work on drum fills, grooves and string sections while in bed could complete the Cubase package.
