An electronic musical instrument includes: a performance controller; and at least one processor, configured to perform the following: instructing sound generation of a first musical tone in response to a first operation on the performance controller; in response to a second operation on the performance controller during the sound generation of the first musical tone, obtaining a first amplitude value of the first musical tone at a time of the second operation, and obtaining a second amplitude value at which a second musical tone is to be sound-produced in response to the second operation on the performance controller; acquiring a parameter value for determining at least one of pitch, timbre, and volume of the second musical tone based on a ratio of the first amplitude value to the second amplitude value; and instructing sound generation of the second musical tone in accordance with the acquired parameter value.

A method for generating a musical score based on user performance during playing a keyboard instrument may include detecting a status change of a plurality of execution devices of the keyboard instrument. The method may include generating a first signal according to the detected status change. The method may include generating a second signal indicating a plurality of timestamps. The method may include determining a tune of the musical score based on the first signal. The method may include determining a rhythm of the musical score based on the second signal. The method may further include generating the musical score based on the tune and the rhythm of the musical score.

An electronic musical instrument includes at least one function operator associated with at least one process, and at least one processor, wherein the at least one processor executes the followings, deciding that musical performance is being performed or not in response to an operation to the at least one function operator, in response to deciding that the musical performance is being performed, executing the at least one process associated with the at least one function operator, and in response to deciding that the musical performance is not being performed, not executing the process associated with the at least one function operator, despite being operated to the at least one function operator.

A switch device (4, 5) includes: a cap (7) including, on a top surface (711), a first region (71a) and a second region (71b) corresponding to a position where an internal light (133) is disposed and being thinner than the first region (71a); and a switch (61, 62) to which the cap (7) is mounted.

A micro flame effects unit (MFEU) includes a solenoid valve, an ignition coil, and a pair of electrodes. The ignition coil is to receive a voltage to create a spark between end portions of the electrodes. The solenoid valve is to receive a voltage to release gas, the spark and the gas to create a flame effect. An example flame thrower pipe organ (FTPO) includes a set of cylindrical members with a micro flame effects unit (MFEU) located within each cylindrical member. The FTPO further includes a set of keys that provide a sound when a key of the set of keys is played. A control device causes an MFEU to release a flame effect concurrent with the sound of a corresponding key being played. The FTPO may be automated with a self-playing system.

A keyboard sustain pedal stabilizer is for use with a keyboard sustain foot pedal. The keyboard sustain pedal stabilizer comprises a stabilizer base, and a pedal-retention area in cooperative engagement with the stabilizer base. The pedal-retention area includes a retaining structure, the retaining structure enabling secure retention of the keyboard sustain foot pedal within the pedal-retention area. The retention structure may be an end-wall in combination with a pair of opposing sidewalls, a recess in combination with a pair of opposing sidewalls, or a recess in combination with an end-wall. The keyboard sustain pedal stabilizer may also include an expanded position and a retracted position, the expanded position being for cooperative engagement with the keyboard sustain pedal, the retracted position being for transporting the keyboard sustain pedal stabilizer. The under surface of the stabilizer has non-slipping properties.

Different aspects of the invention implement a sensor module that can be configured as a keyboard module or as a pedal module, allowing to connect a plurality of keyboard and pedal modules to assemble a configuration to the user’s liking, such as, for example, the usual configuration of an 87-key piano together with two pedals. The sensor module transmits information about detected key or pedal strokes to a computer application for playback, either aural or visual. At the same time, the sensor module allows, both in the keyboard module and pedal module configuration, to transmit the feeling of playing a real piano.

A keyboard device for a keyboard instrument includes a keyboard chassis, a plurality of keys arranged side by side in an upper portion of the keyboard chassis, and a plurality of hammers provided in association with the plurality of keys, respectively. Each hammer is pivotally supported, below an associated key, via a hammer support shaft on the keyboard chassis, and is pivotally moves in a manner interlocked with depression of the associated key. For a predetermined first hammer, which is associated with a predetermined first key of the plurality of keys, and a predetermined second hammer, which is associated with a predetermined second key of the plurality of keys, respective angles of pivotal movement, caused by key depression, of the first hammer and the second hammer are set to be different from each other.

A keyboard device for a keyboard instrument includes a keyboard chassis having a plurality of partition walls, a plurality of keys, and a plurality of hammers pivotally moved along with key depression. Let-off members are removably mounted on one of each adjacent two of the partition walls and one of the hammers disposed between the adjacent two partition walls. Engagement portions are provided on the other of each adjacent two of the partition walls and the one of the hammers disposed between the adjacent two partition walls. The engagement portions are temporarily engaged with the let-off members during pivotal movement of the hammer along with depression of a key, to thereby add let-off feeling to touch feeling of the depressed key.

A key for a keyboard device includes a resin key body and one or a plurality of woody boards attached along at least part of a side surface of the key body. The key body includes an upper convex part which extends along an upper end of the side surface and is formed continuous with on upper surface of the key body such that it protrudes in a lateral direction of the key body, and a lower supporting protrusion which is disposed in the vicinity of a central portion or a lower end of the side surface such that it protrudes in a lateral direction of the key body and is opposed to the upper convex part. The woody board is sandwiched by the upper convex part and the lower supporting protrusion.
