Pianoteq 4 Stage and iPad control app

Hello,

I use "Pianoteq 4 Stage" with the iPad app "TB MIDI Stuff" to control Pianoteq from my iPad (by wi-fi). It works great.

Is it possible to do the opposite ? For example, when I change de volume on Pianoteq, the slider on my iPad app change in real-time ?

The iPad app seems to be ok to receive midi controls changes messages.

Sorry for my poor english...
