A device integrally joined with the ported opening of a musical bass drum resonant drumhead for regulating the amount of vibrating airflow passing through the inside of a bass drumshell and continuing through the ported opening for effectively controlling undesirable higher frequency drum sounds precipitated by the airflow produced upon the striking of the batter head.

An electronic-drum module for connection to one or more electronic-drum pads is provided. The module includes an electronic display; a first memory storing audio files for playback when the playback is triggered by a signal received from a pad; and one or more processors coupled to the display and the memory. The processors are configured receive an instruction to transfer a set of samples. The set of samples is associated with a priority-instruction and includes a first subset of samples and a second subset of samples. The processors are also configures to transfer the first subset of samples from a second memory to the first memory based on the priority-instruction before transferring the second subset of samples and to transfer the second subset of samples from the second memory to the first memory.

Provided are an electronic percussion instrument and a hit detection method. An overhang portion constituting the outer edge part of an edge frame is positioned further radially outward than the outer edge of a bow frame. Consequently, when the overhang portion is hit, the vibration resulting from the hit is detected by an edge sensor attached to the edge frame. In this way, it is possible to detect whether the overhang portion (the edge portion of an electronic cymbal has been hit by means of vibration detection by the edge sensor instead of by means of pressure detection by a sheet sensor.

An electronic percussion instrument capable of simulating a rendition of an acoustic percussion instrument is provided. The electronic percussion instrument includes a housing, a percussion surface attached to the housing, a pressure sensor disposed on a central section of the percussion surface on a side of the back surface and configured to detect pressing against the central section, a head vibration sensor disposed on a peripheral section of the percussion surface on the side of the back surface and configured to detect vibrations of the peripheral section, and a rim vibration sensor disposed at a position overlapping the head vibration sensor when seen in a plan view of the percussion surface and configured to detect vibrations of the housing.

An electronic percussion instrument, electronic musical instrument, information processing device, and information processing method are provided. The electronic musical instrument includes a control device that performs processing in which an envelope indicating a change in a reference value over time for determining whether vibration of the second playing operation element is self-induced vibration or excited vibration entailed by vibration of the first playing operation element is generated based on a waveform indicating vibration of the first playing operation element, and processing in which information on the basis of excited vibration of the second playing operation element is prevented from being included in information indicating operation of the second playing operation element using the reference value indicated by the envelope.

A drumhead includes a membrane with ferrous responsive material printed onto a surface or otherwise incorporated into it. The ferrous responsive material is detectable by an electromagnetic sensor such that striking the membrane causes vibration that is detected by the sensor, which may initiate an acoustic sound via a sound module. The drumhead may thus be used in an electronic drumming system without requiring fixation of a foreign object to a surface of the membrane.

A percussion instrument, in particular electronic percussion instrument, includes at least one main attack element having at least one main attack surface and with a position detecting unit which is at least provided to detect an attack position of the main attack surface. The position detecting unit comprises at least two position detecting elements which are arranged decentrally with respect to the main attack surface, at least when the main attack surface is viewed perpendicularly.

A percussion instrument is adapted with a foam arrangement directly or indirectly in communication with its percussion surface. The foam arrangement reduces acoustic impact sounds when the instrument is struck, helps isolate vibrations from nearby percussion surfaces, and reduces or removes sound generation when air is released from the damper. To achieve these results, directly or indirectly secured to the percussion surface is an open-cell foam layer that is configured with a closed-cell foam layer positioned in a lateral side-by-side arrangement to create a spring and damper system. The open-cell foam may have one or more holes that extend entirely through its body, and inside those, one or more holes are closed-cell foam to provide additional spring-like functionality. The side-by-side dual-layer arrangement enables the closed- and open-cell foam layers to operate in tandem—the closed-cell layer operates as a spring, and the open-cell layer operates as a damper.

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.
