I was so impressed by the plyability of the Synchron Pianos that finally I decided to buy a hammer-action controller, and after a bit of research, the Kawai VPC-1 appeared to be the best quality-price choice for my purpose (just getting the keyboard reacting the closest possible to a real piano, and nothing else, since I've plenty of controllers already for other MIDI functionalities).
The product is amazing and the feeling is fantastic, but due to the precision of the keyboard, the velocity curve is a real key to get what you want: the instrument has default curves for several libraries and virtual pianos, but unfortunately not for VSL.
The default for instance is not working well for VSL, but the preset "Heavy" velocity curve works fine for my touch with Synchron Pianos, but I was wondering if anybody else is using this controller, and in case if we may share feedback and curves.
