摘要:
The electronic musical instrument comprises a plurality of slide-type faders (1), an interval setup device (5, 6), and a sound synthesis device (20). The slide-type faders are provided correspondingly to a plurality of tones included an interval and allow slide operations to change output sound volume. The interval setup device means sets the interval to define a tone for each slide-type fader. The sound synthesis device synthesizes sounds according to a volume changing pattern with predefined sound quality and based on operations of the slide-type fader. The slide-type faders can be manipulated by fingertips or the like for musical performance to enjoy the DJ play without many practices or high proficiency.

This invention relates to a record player used for a disc jockey (DJ), and more particularly to a record player suitable for a so-called scratch performance operation by which a phonograph record is directly rotated in forward and reverse direction to output new artificial sound by fingering of an operator which is a kind of DJ performance pattern. In order to suppress the needle skip caused when forwardly/inversely rotating the phonograph record by the finger operation, the positional relationship between the record groove on the turntable and the supporting point P of the arm shaft is defined so as to suppress inward and outward component forces applied to the needlepoint of the cartridge as possible. Therefore, three points, i.e., a start point R and an end point S of the record groove on a straight line B extending from the rotating shaft core C of the turntable in a radial pattern and a rotation center of a tone arm, namely, the supporting point P may form an isosceles triangle with the point P as an apex in a most preferable mode.
