US 5,198,603 A · Automatic data-prereading playing apparatus and sound generating unit in an automatic musical playing system

Abstract

An automatic musical playing playing system including an automatic playing apparatus and a sound generating unit incorporated in combination therewith, the apparatus comprising: a first memory for storing musical playing data arranged to be sequentially preread; a calculator for calculating an actual length of time required to play music based on the preread musical data and/or for calculating an actual quantity of playing information in said data; a comparator for deciding whether or not the actual length of time is less than a predetermined length, and/or whether or not the actual quantity is less than a predetermined quantity; a first reading device for sequentially prereading from the first memory the musical data prior to an actual timing for playing, in a case where the above decisions are affirmative; and an output for outputting the preread musical data wherein the above unit comprises: an input for receiving the preread musical data; a second memory for temporarily storing said data from the input; a second reading device for sequentially reading from the second memory means said data at a predetermined timing; and a musical tone-generator which generates and/or mutes musical tones for playing music according to said preread musical data.

Dependent claims

An automatic playing apparatus for a musical data-prereading playing system, the apparatus comprising:

(a) a first memory means for storing musical playing data representative of music to be played in a time sequence arrangement;
(b) output means;
(c) calculating means for calculating an actual quantity of playing information included in preread musical playing data;
(d) comparing means for determining whether or not the actual quantity of playing information is less than a predetermined quantity of information;
and
(e) a first reading means for sequentially prereading musical playing data from the first memory means prior to when the music is to be played, and for applying preread musical playing data to the output means only when the comparing means determines that the actual quantity of playing information is less than the predetermined quantity of information, the quantity of playing information included in the musical playing data increasing as the first reading means prereads musical data, and decreasing as music represented by the preread musical playing data is played.
