Abstract: For the segment class designation the temporal position of segments in two candidate segment classes is used for the stanza/refrain selection by means of a segment class designation means, wherein the highest-order segment class is designated as refrain segment class only when it has a segment following temporally later in the audio piece than the latest segment of the other candidate segment class. With this, segment class labeling with a low error rate is achieved, which can at the same time be implemented with easy effort and is further predestined for automated flow.

Abstract: A joystick control (20) mounted on the body (12) of an electric guitar (11) adjacent to the customarily picked section of the strings (16) provides convenient simultaneous independent gain control of two pickup signals. A pick may be held between the thumb and first finger of the picking hand while the joystick handle assembly (23) is manipulated by any free finger or fingers of that hand. This system allows smooth, quick, easy manual selection of two independent instrument voices, alternately or simultaneously in any proportion, with minimal disturbance to the player's picking. Picking strings while varying the signals' volume levels can produce desirable timbre changes, swells, and tremolo. A waveform polarity switch (19) optionally reverses the polarity of one pickup signal. When the signals are out of phase, the change in tone of their combined voice as the joystick travels is complex.

Abstract: A shock absorbing roller thumb wheel is disclosed. The shock absorbing thumb wheel includes a central hub that can be secured to an electro-mechanical switch, a rim encircling the central hub, and force dispersion spokes extending from the central hub and connected to the rim. The configuration of the force dispersion spokes and the resilient material of the force dispersion spokes and the rim allow for radial and lateral deflection of the rim in response to an applied impact force.

Hence, the probability of connection failures is reduced, and the lifetime of a device that uses the thumb wheel can be extended.
