Abstract: A method for facilitating real-time interaction between a first and second player of a music-based video game via a network having unpredictable delivery latency, the first player located remotely from the second player, includes displaying to a first player target musical data associated with a musical composition, receiving music performance input from the first player via a controller resembling a first musical instrument, displaying to a second player, the second player located remotely from the first player, target musical data associated with the musical composition, and receiving music performance input from the second player.

Abstract: Systems and methods for a creating a music-based video game are described as is a portable music and video device housing a memory for storing executable instructions and a processor for executing the instructions. Creating video game content using musical content supplied from a source other than the game includes analyzing musical content to identify at least one musical event extant in the musical event; determining a salient musical property associated with the at least one identified event; and creating a video game event synchronized to the at least one identified musical event and reflective of the determined salient musical property associated with the at least one identified event.

Abstract: Optional accompaniment patterns are created on the basis of a plurality of parameters. Thus, by changing the values of the parameters to be supplied as necessary, accompaniment patterns can be created in an unconstrained manner. By time-varying at least one of the parameters, an optional accompaniment pattern can be created in such a manner that a desired accompaniment tone is sounded at a desired time point, and an accompaniment pattern can be changed freely. A performance state of an performance operator such as a keyboard may be detected, so as to change the parameters on the basis of performance states detected at least for a current time and a given past time. This permits parameter control reflecting a changing real-time performance state. Alternatively, a parameter may be prepared in accordance with input performance information so that an accompaniment pattern is created on the basis of the prepared parameter.

Abstract: A pattern memory stores plural accompaniment patterns for each of plural accompaniment components. Each of the accompaniment components is composed of one or more musical instrument parts for an accompaniment performance. There are provided operating members which are used for selectively designating a desired component and a touch sensor for detecting an operation touch applied to the operated operating member. Any of the plural accompaniment patterns corresponding to the designated component is selected in accordance with the detected operation touch, and the selected accompaniment pattern is read out from the memory. The entire accompaniment performance pattern is provided by a combination of the accompaniment patterns thus selected for the respective components. In order to allow the selected pattern to be changed freely, modifiers representing how to make the change may be utilized by the user.
