This C7 virtual piano is an absolute joy to play, and meticulously sampled and programmed. A very high quality instrument. Having extensive playing experience with high end acoustic pianos, I'm very demanding of sampled pianos and the Acousticsamples C7 is rated in my top 3. Every time I load it up and play, I get lost in the music, not distracted with performance or playability problems like so many others. The best software instrument purchase in a long time.
