| 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. |
