Robotic drummers include voice coil actuators that are coupled to linear-to-rotary motion convertors to produce drumstick rotations so as to strike a drum head. Such rotations can be triggered via a microprocessor using stored performance data, by a user with a mouse, trackpad, joystick, or other user input device. Performances are enhanced by driving the VCA with drive signals have random variations associated with strike timing, amplitude, location, and speed. Multiple strikes are provided by reducing, eliminating, or reversing drumstick rotation with a corresponding drive signal upon detection of drumstick contact with the drum head.

A data generation device includes: an acquisition part configured to acquire measurement data that corresponds to measurement values, obtained in chronological order, corresponding to a behavior of a key or a member coordinating with the key for each of a plurality of keys; and a data generation part configured to generate display data for displaying a screen showing the measurement values corresponding to each of the plurality of keys along a time axis based on the acquired measurement data.

This present invention relates to a stringed musical instrument with an integrated touch video screen allowing a user to play the instrument while singing along with a variety of pre-recorded songs. The video screen displays the words and other information of a user selected song. More specifically, the stringed musical instrument has built in karaoke components and the strings of the instrument can be strummed by the user to play a melody, or the user may mimic playing the instrument strings, wherein the sounds emitted from the strings can be muted.

Various methods are presented that facilitate the connection of a speaker system to a separate functional system. In some embodiments, the connection is made through a male and female connector designed to twist into a locking position. In other embodiments, the connection is made by a guided connection with beveled edges to facilitate correct alignment of the speaker system. In still other embodiments, the connection includes mechanical locking mechanisms with a quick disconnect feature. In other embodiments, the connection also facilitates transmission of electrical signals through the connector.

A Bohemian Instrument may be a musical instrument, acoustic or electric, with a metallic semi-hollow or hollow body. The Bohemian Instrument may comprise a neck extending from the body. In various embodiments, the Bohemian Instrument may comprise, but not be limited to, for example, a through-body neck, extending from the head of the neck into the body of the instrument. Within the body, the Bohemian Instrument may comprise a frame reinforcing at least one inner-edge of the body. In various embodiments, the frame within the body may be comprised of wood and be connected to, or comprise a part of, the through-body neck. By reinforcing the body, the frame also serves to improve a resonation quality of the hollow or semi-hollow metallic body. In turn, the Bohemian Instrument's unique and distinct sound is further articulated.
