[0044] Structure of automatic player piano

[0045] Referring to FIG. 1 of the accompanying drawings, an automatic player piano embodying the present invention mainly includes an upright piano 1 , an automatic playing system 10 and a recording system 80 . A human player plays a piece of music with his fingers on the upright piano 1 , and acoustic piano tones are produced in the upright piano 1 along the bars of the piece of music. The automatic playing system 10 and the recording system 80 are installed in the upright piano 1 . The original performance on the upright piano 1 is recorded by the recording system 80, and the automatic performance system 10 reproduces the performance on the upright piano on the basis of the musical piece data.

[0046] The upright piano 1 includes a keyboard 1 a having black keys 1 b and white keys 1 c , action units 2 , hammers 3 , strings 4 , dampers 39 and a piano cabinet 90 . An inner space is defined in the piano case 90 , and the action ...

[0155] The automatic player piano implementing the second embodiment is similar to the automatic player piano already described except for the job sequence of the subroutine S8' for determining the reference key trajectory group. The subroutine S8' forms a part of the computer program for realizing the automatic player piano of the second embodiment. The main routine and other subroutines are the same as those of the computer program installed in the automatic player piano realizing the first embodiment. For this reason, only subroutine S8' is described.

Abstract

An automatic player piano is a combination between an acoustic piano (1) and an automatic playing system (10), and a grand piano and an upright piano are used as the acoustic piano; the grand piano has action units prompter than action units of the upright piano so that a half-stroke recorded through the grand piano is not reproducible by the upright piano; the automatic playing system (10) causes the hammers (3) to rotate toward the strings (4) without any escape, thereby compensating the poor promptness with the short keystroke of the keys (1b, 1c) until the rotation of hammers (3).

Description

technical field [0001] The present invention relates to an automatic player musical instrument, and more particularly, to an automatic player musical instrument that reproduces tones along the bars of a musical piece on the basis of musical piece data codes. Background technique [0002] A piano is a typical example of a keyboard musical instrument, and an automatic player piano is a combination between a piano and an automatic playing system. Similar to a human pianist playing a tune on a standard acoustic piano, a human pianist plays a tune on an automatic player piano. The automatic playing system reproduces the performance on the piano without any fingering of a human player, and makes it possible to enjoy the tune. [0003] In the following description, the term "front" indicates a position closer to a human player who is ready to play a tune than a position modified with the term "rear". A line drawn between the front position and the corresponding rear position exte...
