Abstract:
A data converter having certain converting characteristics from first music data representative of a performance to second music data for use a given automatic player piano, said converting characteristics being defined by:first data information common to automatic player pianos and containing a first parameter indicative of a relationship between a forward key velocity and an impact time and a second parameter indicative of a relationship between said forward key velocity and a final hammer velocity; andsecond data information unique to said given automatic player piano and containing results obtained through learning:a) a difference between a forward key trajectory produced from said first parameter and a virtual forward key trajectory targeted by said automatic player piano;b) a time difference between a starting timing of a depressed key moved along said virtual forward key trajectory and an actual key depressing timing in order to cause said forward key trajectory of said automatic player piano to converge to said virtual forward key trajectory;c) a difference between a backward key trajectory produced from said first parameter and a virtual backward key trajectory targeted by said automatic player piano; andd) a time difference between a virtual releasing timing of a released key moved along said virtual backward key trajectory and an actual key releasing timing in order to cause said backward key trajectory of said automatic player piano to converge to said virtual backward key trajectory.
