Musical performance-related information output device, system including musical performance-related information output device, and electronic musical instrument
First Claim
1. An output device comprising:
- a first acquirer configured to acquire a signal including an audio component;
a second acquirer configured to acquire modulated data code string included in a frequency band higher than a frequency band of the audio component; and
an output interface configured to output the signal together with the modulated data code string sequentially to emit a first sound from a speaker,wherein the modulated data code string in the first sound output from the speaker contains instructions for controlling a second sound to be emitted from an external device, the second sound being different from the first sound.

Abstract
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.
