Abstract: The disclosure provides a server, an electronic device, a server communication method, a device communication method, and a communication system. In loading of a communication system, in the case where an identifier of a timbre data and an instruction for loading the timbre data are transmitted from a mobile terminal to a server, the server acquires the timbre data corresponding to the identifier of the timbre data from a timbre DB, and transmits the timbre data together with the received instruction to a communication device (electronic musical instrument). In the electronic musical instrument, the received timbre data is stored to a work memory in response to the instruction received from the server.

Abstract: A flight speaker 1 firstly outputs an inspection sound while flying on a first route R1 in a linear shape connecting a position of a sound collecting microphone M disposed inside a concert hall P1, and identifies an optimal volume position where a volume of a received sound collected by the sound collecting microphone M becomes an expected volume. The flight speaker 1 outputs an inspection sound while flying on a second route R2 in an arc shape with a distance between the identified optimal volume position and a position of the sound collecting microphone M as a diameter, and identifies an output position where a sound waveform of the received sound from the sound collecting microphone M becomes an expected sound waveform.

Abstract: Provided is a transmitter for musical instrument and a mode switching method thereof. A transmitter for musical instrument which is mounted on an electric guitar determines the electric guitar is in a not-in-use state when a continuation time in which a square sum of accelerations output from a three-axis acceleration sensor is smaller than a power-saving threshold value is longer than a power-saving transition time, and the transmitter transitions from a normal mode to an energy-saving mode. On the other hand, when the accelerations in the energy-saving mode becomes equal to or greater than a release threshold value from a state of being smaller than the release threshold value or becomes equal to or smaller than the release threshold value from a state of being greater than the release threshold value, the electric guitar is returned from the energy-saving mode to the normal mode.

Abstract: A keyboard device and a key depression information detecting method are provided. The keyboard device includes: a coil generating a magnetic field; a displacement member having an outer surface and displaced at a position facing the coil during key depression; and a conductor provided on the displacement member. The conductor includes: a facing portion covering the outer surface of the displacement member to face the coil during key depression; and a front surface portion connected to the facing portion and covering an outer surface of the displacement member which is directed to a front side in a displacement direction of the displacement member.

Abstract: [Problem] To provide an arpeggiator enabling musically natural arpeggio playing to be achieved, and a program comprising a function therefor. [Solution] In the present invention, a synthesizer 1 resets the number of octaves in an octave counter memory 12d to zero at the beginning of each bar when an octave reset function is on. Due to this configuration, sounds generated at the beginning of each bar, that is, when the step count is 0, all have the same note number. Consequently, a sound generation timing-based cycle of an arpeggio pattern of each bar can be synchronized with a pitch variation-based cycle, making it possible to give a listener the impression that a consistent phrase is being played.

Abstract: An image processing device is provided. The image processing devices includes an input part configured to input an input image; a cutout part configured to cut out a plurality of image regions from the input image input by the input part; and a luminance change part configured to execute luminance change of each of the image regions cut out by the cutout part.

Abstract: An electronic musical instrument, method for a musical sound generation process and a non-transitory computer readable medium that stores an electronic musical instrument program are provided. The program causes a computer provided with a storage part to execute a musical sound generation process using sound data. The program causes the computer to execute: acquiring, from the storage part, first sound data and first user identification information indicating a user who has acquired the first sound data from a distribution server; acquiring second user identification information indicating a user who causes the musical sound generation process to be executed using the first sound data; determining whether or not the first user identification information matches the second user identification information; and inhibiting execution of the musical sound generation process using the first sound data in a case when the first user identification information does not match the second user identification information.
