Percussion devices are described employing sensor arrays based on piezoresistive materials.

A reproduction control method, which is executed by a computer, includes determining, based on an image showing an object, whether a type of the object is a first type or a second type that is different from the first type, and reproducing a sound, triggered by a striking of an operation surface by the object, based on a result of the determining.

A frame body fixed to a membrane 10 is divided into multiple long-side frame bodies 11 and a short-side frame body aligned in a peripheral direction of a frame 3. Tension is applied to the frame body 10 by pulling each frame body 11, 12. Accordingly, it is not necessary to make the shape of each frame body 11, 12 consistent with the frame 3 (support part 30) in a complicated polygonal shape, and the shape of each frame body 11, 12 can be formed as a linear shape. Therefore, the shape of each frame body 11, 12 hardly varies. In addition, even if the shape of each frame body 11, 12 varies, tension can be uniformly applied to the membrane 10, as it is configured that each frame body 11, 12 is pulled to apply tension to the membrane 10.

Various embodiments are provided generally relating to providing a strum pad on a user device. In some embodiments, a musical arrangement may be provided on a user device. A score of the musical arrangement may be tracked as it plays. In some embodiments, gestures may be detected on the user device while the user device plays the musical arrangement. In response to detecting the gesture, a component piece for the musical arrangement may be outputted. In some embodiments, the outputted component piece may correspond to the tracked score of the musical arrangement.

An electronic device according to an embodiment of the present disclosure includes at least one memory configured to store executable instructions, and a processor configured to execute the executable instructions stored in the at least one memory to cause the electronic device to acquire a first sound signal from an external source, generate a musical sound signal according to a performance operation, output the first sound signal and the musical sound signal to a first output destination, and output the musical sound signal to a second output destination different from the first output destination.

Methods, systems, and storage media for generating a beatbox transcript are disclosed. Some examples may include: receiving an audio signal having a plurality of beatbox sounds, generating a spectrogram of the audio signal, processing the spectrogram of the audio signal with a neural network model trained on training samples including beatbox sounds, generating, by the neural network model a beatbox sound activation map including a plurality of activation times for a plurality of beatbox sounds, decoding the beatbox sound activation map into a beatbox transcript and providing the beatbox transcript as an output.

A hit detection device that detects vibrations in an object includes a vibration transmission member and two vibration detection sensors. The vibration transmission member includes a contact portion in contact with the object, and deforms in response to the vibrations in the object. The sensors each detect deformation in each of two different portions of the vibration transmission member. The two portions of the vibration transmission member are arranged in a direction intersecting an alignment direction in which the object and the vibration transmission member are aligned.

This control device for an electronic percussion instrument inputs a musical sound signal corresponding to a hit on a struck surface to a first amplifier for amplifying a signal to be connected to a first speaker disposed on the back side of or around the struck surface, and inputs the musical sound signal to a second amplifier for amplifying a signal to be connected to a second speaker disposed on the back side of or around a first struck surface at a timing later than a timing at which the musical sound signal is inputted to the first amplifier.
