Cease and desist letter[]

In a letter dated 26 March 2007, Activision requested that Piegdon "immediately cease any and all use of the "Piano Hero" name in connection with the distribution and promotion of [his] video game and agree not to use such in the future". Piegdon responded by hosting a contest for a new name for the project, resulting in the name, Synthesia, suggested by Daniel Lawrence
