Abstract
A music system including a musical instrument, such as a keyboard strummer, in which the musical notes produced by the playing of the instrument are controlled by musical assistance data mapped unto the instrument keys and strum vanes from tracks specially prepared and synchronized with a prior performance of the piece. Modified mass media, such as CD ROM, TV signals and video cassettes are provided including synchronized note assist data and additional media, such as ROM packs or tone encoded audio cassettes or CDs, are provided with synchronizable note assist data for use with unmodified mass media.

9. A method for assisting a musician to produce a musical rendition related to pre-recorded music, comprising the steps of:
-
recording one or more tracks of note assist data synchronized to a studio performance of the pre-recorded music, each track of note assist data representing a musical component of the original music; deriving a master sampling interval of samples of a beginning portion of the pre-recorded music; deriving performance samples of a beginning portion of a session performance of the pre-recorded music; forming a series of sequential performance sampling intervals from subsets of the performance samples; comparing each performance sampling interval to the master sampling interval to determine the correlation therebetween; synchronizing the note assist data with the session performance in accordance with the correlation; producing key signals in response to musical instrument actuation by the musician during the session performance of the pre-recorded music; and producing a rendition related to the pre-recorded music in response to the key signals modified by the note assist data provided at the time of the actuation that produced each such key signal. - View Dependent Claims (10, 11)
