A little classic

GEM was one of the first companies in developing physical modeling technology; their R&D worked together IRCAM (Paris), CSELT (Turin) and CSC (Padua), obtaining the powerful engine inside the RealPiano line. This expander isn't that advanced like the current production, but already has features like sympathetic resonance and pedal noise. The grand piano is pleasant, while the Rhodes shows some audible artifacts. There are even a tonewheel organ, strings ensemble and it can do split/layer. It does recognise sustain half-pedal.
