摘要：
Provided are a musical performance-related information output device and a musical performance system capable of superimposing musical performance-related information on an audio signal without damaging the general versatility of the audio signal. The musical performance-related information output device includes a musical performance-related information acquiring section that is adapted to acquire musical performance-related information related to a musical performance of a performer, a superimposing section that is adapted to superimpose the musical performance-related information on an analog audio signal such that a modulated component of the musical performance-related information is included in a band higher than the frequency component of the analog audio signal generated in accordance with the musical performance manipulation of the performer, and an output section that outputs the analog audio signal on which the superimposing section superimposes the musical performance-related information.
