Pianist is a piano simulator. th newest update has improve the sound produced by keys and give us the opportunity to raise and lower the volume, the developer has also changed the name of the application because the old name, was meaning something way different with some languages.  Pianist is available in the category “Toys” of adding the source ModMyiFone which is part of Community Sources. the older version allowed pressing more keys simultaneously, but I admit that the sound is much more beautiful now, and that is an exchange worth taking
