its possible that a company has bought waldorf,pay their debts and rebuilding it,manufacturing the old products or maybe working on a new machine.
remember that waldorf were on the top of their game 2 years ago and rather equal access and over stronger then clavia and alesis on the VA market,but that was 2 years ago and their former flagshop Q is alot weaker then the TI,Ion,Korg radiate and so..
