Ketron audya update

Ketron italy reply me an email that a new update will be soon released, the update is to allow user use .msp as a drum set (like turkish update for audya 5 5.3g beta version). I really need this on my audya 4 and i dont understand why ketron reply me by email that will be soon released in april, and two months later, there is nothing.
Any one have news about this update???

Soon it could be years according to the history of Ketron
they give only empty promises
