Abstract: An information processing system includes an image obtaining circuit and a display control circuit. The image obtaining circuit is configured to obtain observation images of a first keyboard of a first keyboard instrument. The display control circuit is configured to display, on a display device, the observation images and reference images. The reference images include moving images of at least one hand and one or more fingers of a reference performer who is playing a second keyboard of a second keyboard instrument. The at least one hand and the one or more fingers of the reference performer are displayed overlapping the first keyboard included in the observation images.

Abstract: A sound processing system includes an electronic musical instrument and a sound processing apparatus communicable with the instrument. The instrument includes an audio signal generator that generates an audio signal according to a user performance on the electronic musical instrument, a first signal processor that performs first effect processing on the audio signal to generate a first processed audio signal, a first sound emitter that emits a first performance sound component based on at least one of the first processed audio signal or a second processed audio signal, and a first audio signal output that outputs the audio signal. The apparatus includes a first audio signal receiver that receives the audio signal output from the first audio signal output, in a state where the instrument is communicating with the apparatus, a second signal processor that performs second effect processing on the received audio signal, including removing a direct sound component from the received audio signal, to generate the second processed audio signal, and a second sound emitter that emits a second performance sound component based on the second processed audio signal. In the state where the instrument is communicating with the apparatus, the first signal processor changes the amount of the first effect processing to the generated audio signal in generating the first processed audio signal that is emitted by the first sound emitter, in a state where the audio signal is not output to the apparatus, or the first sound emitter emits the second performance sound component based on the second processed audio signal.

Abstract: A control device in one embodiment includes a first transmission unit, a first receiving unit, and a first generation unit. The first transmission unit is configured to transmit first performance data including contents of playing a keyboard instrument at a first communication base to a second communication base. The first receiving unit is configured to receive second performance data from the second communication base. The first generation unit is configured to generate a drive signal to produce a sound in accordance with the second performance data and output the drive signal to a sound generation device at the first communication base. At least one of the first performance data and the second performance data includes a key position signal indicating a key press amount on the keyboard instrument.

Abstract: A method of controlling communication includes obtaining a result of comparison between a first feature value of first streaming data and a second feature value of second streaming data and transmitting a first switching signal to a first terminal and a second terminal in the case where the first feature value and the second feature value have a first relation according to the comparison result. The first feature value is of a first streaming data transmitted from the first terminal using the first communication method type. The second feature value is of a second streaming data transmitted from the second terminal using the first communication method type. The first switching signal causes the first terminal and the second terminal to switch from using the first communication method type to using a second communication method type to transmit streaming data between the first terminal and the second terminal.

Abstract: An audio processing system includes at least one memory storing a program and at least one processor. The processor implements the program to analyze an audio signal including sound from a first sound source; identify, based on the analysis of the audio signal, a series of sound indicators each representing a certainty that audio components of the first sound source are included in the audio signal; identify a series of pitches, each relating to the components of the first sound source; and cause a display device to display the series of the sound indicators and the identified series of the pitches along a common time axis.

Abstract: A computer-implemented reproduction control method includes reproducing sound from sound data representing a series of sounds including first sound and second sound that follows the first sound. The method includes starting reproducing the first sound, continuing the reproduction of a first sound until an end of the first sound in response to receiving a first instruction in a reproduction period of the first sound, stopping the reproduction of the first sound, and after the stopping of the reproduction of the first sound, starting reproducing the second sound in response to receiving a second instruction provided by a user.
