ABSTRACT:
An automatic musical playing system includes an automatic playing apparatus and a sound generating unit. The playing apparatus includes: 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 such data; a comparator for deciding whether or not the acutal length of time is less than a predetermined length of time, 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 time for playing when the comparator decision/decisions is/are affirmative; and an output for outputting the preread musical data. The sound generating unit includes: an input for receiving preread musical data; a second memory for temporarily storing data from the input; a second reading device for sequentially reading from the second memory, data according to a predetermined timing; and a musical tone-generator which generates and/or mutes musical tones for playing music according to the preread musical data.
